Is your headphone amplifier making a noticeable background **hiss** or **white noise**? Don’t worry—your unit is likely working perfectly. **Headphone amps _for pedalboards_** are often designed to be loud and powerful, which can sometimes reveal background noise you might not hear through a regular guitar cabinet. In many cases, the “hiss” isn’t a fault in the pedal—it’s just a setup issue. Here’s a **2-minute checklist**  to get your practice rig actually silent. Also make sure to check our headphone amps **1. Check Your Volume Balance **_(Gain Staging)_ This is the #1 cause of hiss. If you send a very quiet signal into the headphone amp and then crank the amp’s volume to hear it, you’re amplifying the background noise along with your guitar. **-- >** _The Fix:_ Turn the volume UP on the pedal or preamp before the headphone amp. If you headphones amp has an INPUT knob, make sure to also turn it all the way up, or until the point that distortion might occur. Then, turn the headphone amp’s volume DOWN. You’ll get the same loudness but a much cleaner sound. **2. Watch Out for Sensitive In-Ears** Not all headphones are the same. Modern in-ear monitors (IEMs) can be very sensitive. They can pick up the “noise floor” of analog gear more than larger studio headphones. **-- >** _The Fix:_ If the hiss is annoying with earbuds, try plugging in a pair of over-ear headphones. The background noise usually disappears immediately. **3. Check the impedance of your headphones** Most headphone amp manufacturers list the recommended headphone impedance in their specs, and they should provide this information if you need it. Using headphones outside this range—either too low or too high—can affect sound quality and increase background noise. **-- >** _The Fix:_  If your headphones don’t match the amp’s recommended impedance, try using a pair that falls within the suggested range (or slightly higher) for optimal performance. **4. Isolate Your Power** Headphone amps are usually at the very end of your signal chain. If they share a power source with other digital pedals (like reverbs or delays), digital clock noise or other noises can leak in and cause whining or hiss. **-- >** _The Fix:_ Give your headphone amp its own isolated output on your power supply. Avoid daisy-chain cables if possible. **5. “Garbage In, Garbage Out”** A headphone amp acts like a magnifying glass—it amplifies everything fed into it. Noisy pedals or guitar pickups will sound louder through the amp. **-- >** _The Test:_ Turn your guitar volume to zero. If the hiss disappears, the noise is coming from your guitar or earlier pedals, not the headphone amp. **6. The “Phone Charger” Buzz** If you use the AUX input on the headphones amp to play along with backing tracks from your phone or laptop, you might hear a hum or digital whine. This is usually a small ground loop caused by your device’s charger. **-- >** _The Fix:_ Unplug your phone or laptop from its charger and run it on battery power while you play. The hum should vanish instantly. _ _ **_Summary_** Analog headphone amps naturally, even the smaller and simpler ones have a tiny bit of “character” or warmth that digital interfaces don’t, but they shouldn’t be overly noisy. The amount of hiss usually depends on the type of IC used at the amp’s core and other aspects of the circuit design. Follow these steps, and your headphone amp will deliver clean, powerful sound with minimal hiss. _**Important Note:**_ _The tips in this guide are starting points, typical suggestions, not absolutes. Every headphone amp, pedalboard setup, and pair of headphones is a little different, and every musician’s ears and preferences are unique. Use these steps as a framework to troubleshoot and improve your sound, but trust what you actually hear over any rule or recommendation._

Why **_"Active"_** is the only way to route signals without compromising integrity. >> Check our active matrix mixers here << _**Introduction:**_  More Than Just a Splitter__ If you are diving into the world of parallel processing, feedback loops, or complex signal routing, you have likely encountered the concept of a **Matrix Mixer**. Either we are talking about mono or stereo matrix mixer, it is the ultimate tool for sound design—allowing you to send any input to any output, create feedback loops, and blend multiple effects in parallel. But not all matrices are created equal. One of the most common questions I get at dpFX Pedals is about the difference between **passive** and **active**  matrix mixers. While **passive** units are significantly cheaper and require no power, they **suffer** from **inherent physical limitations** that can mess with your tone and the fidelity of the resulting sound. Here is why we strictly design and build Active Matrix Mixers, and why your pedalboard depends on them in case you choose to include them in your setup. **_The Problem with Passive Mixers_** Passive mixers are essentially a network of resistors and potentiometers . They work by attenuating signal through resistive division rather than managing it. When you use a passive matrix, you run into three **unavoidable issues** : **1.   The Cross-talk "Nightmare"** In a matrix mixer, you have multiple inputs and outputs connected together. In a passive design, these connections are never truly isolated. Adjusting a knob on "Channel A" changes the electrical resistance seen by "Channel B." _The Result:_ You turn down one volume knob, and suddenly another volume changes too. It creates a **"leaky" system where signals bleed into paths they shouldn't be in. 2. Impedance Loading **_(Tone Suck)_ Guitar signals are, in most cases, relatively high-impedance. Passive mixers place a h**eavy load** on your signal chain, acting like a _blanket_ over your sound unless preceded by a **buffer**. _The Result:_ You lose high-end sparkle, volume, dynamic range, and overall clarity—the notorious "**tone suck." ** **3. Insertion Loss** A passive mixer cannot maintain unity gain. Just by plugging in, you lose volume that you can never get back without adding a booster pedal later in the chain. Insertion loss is topology-dependent and increases as more signals are summed or split. _**The Active Advantage:** _Why We Use Buffers__ An Active Matrix Mixer uses **operational amplifiers** (Op-Amps) to manage the signal. It requires power, but the **benefits** are non-negotiable for professional audio: - **Effectively isolated through buffering:** We design our mixers with buffered **inputs** and **outputs**. This means every channel is effectively isolated through buffering. You can turn Knob A to 100% and Knob B to 0% without them ever interacting or bleeding into each other. - **Impedance Preservation:** High-impedance inputs ensure your guitar pickups see the load they were designed for, preserving every detail of your treble and attack. - **Unity Gain & Boost:** Active circuits allow us to set the "Unity" volume exactly where it needs to be, or even provide gain to boost a weak signal, if required - **Phase Correction:** Active circuitry allows for **phase inversion**. This is critical in parallel mixing, where blending an effect with your dry signal can sometimes cause phase cancellation (a thin, hollow sound). Active mixers can flip the phase to fix this instantly. Phase inversion is practically unavailable in passive resistor-based matrix mixers, while trivial in active designs. _**Conclusion:**_Don't Compromise Your Routing__ A matrix mixer can be the brain of your pedalboard's routing. Using a passive version is like putting bicycle tires your new car—it might roll, but you'll never get the performance you paid for. Whether you are looking for a standard router or a custom solution for a specific rig, an **active buffering** architecture ensures that the complex sounds you create are exactly the sounds your audience hears. **__** > _**_Quick Note_** > This article is written for musicians, not as a full technical deep dive for engineers. Some concepts are simplified to explain how passive and active matrix mixers behave in real-world pedalboard setups, rather than covering every possible theoretical design or edge case. The focus is on practical use and musical results. _

While there are various types of switch terminals, one of the most common forms used in pedal-building is the **solder-lug** terminal found on panel-mount **electromechanical switches**. **But how do you solder them?** When a switch has solder lugs, they are typically located on its underside, where wire is soldered to the lugs to create a solid, conductive connection. This method forms a permanent bond between the switch and the wire, making solder-lug terminals one of the most **reliable** solutions, even for high-current loads. In these switches, the solder lugs are surrounded by **plastic** , which is prone to **melting** if overheated—especially in cheaper switches. If the plastic melts, it can shorten the switch’s **lifespan** or even render the switch **unusable**. **Tips for soldering without damaging them:** * Use a soldering iron that can be set to the desired temperature.** ** * Tin the wires before attaching them to the switch’s lugs.** ** * Use a no-clean flux if necessary.** ** * **ALWAYS** check the switch’s datasheet provided by the manufacturer for information on the soldering heat resistance of the plastic. A typical specification for small toggle switches is often listed as follows: _- Maximum soldering temperature: 250 °C - Immersion time: 3 seconds - Maximum soldering frequency: 2 times_ * While the above specs is just an example, it applies to a lot of switches out there. If you can't find the datasheet of the switch you have on your hands, use the above specs as a starting point. * Soldering times and temperatures should not exceed the recommended ranges specified for each switch. **Do not operate the switch** during or immediately after soldering—wait at least **2 minutes.** * ** ** If you messed up a soldering, don’t try to fix it right away—wait at least **5 minutes** for the switch to cool. **> **While the next tip is usually unnecessary for pedals, I’m including it for anyone who might find it useful elsewhere, especially when high voltages are involved: * You can’t always add shrink tubing, but covering the solder joint with it helps protect against debris that could cause corrosion and also reduces strain. Adding an epoxy seal to the bottom of the switch is another way to provide extra protection. - DIY Tips -_ _

 **Piezo pickups** are extremely sensitive, and often that’s both their biggest strength and their biggest problem. They can capture the natural attack and character of an acoustic instrument — but only if they’re connected to the right kind of input. Most amps, pedals, and mixers simply don’t have the  high-impedance input a piezo really needs, which often results in a **thin** , **nasal** , “quacky” sound, or even **boomy** if the amp is set in loud volume, which often causes annoying feedback. _That’s where a**piezo buffer** comes in._ A proper buffer presents the pickup with a very high input impedance (in this case around **10MΩ**), allowing the pickup to respond the way it was designed to. The result is a **fuller** , more **natural** tone with better **dynamics** and less noise. Subtle details — like the **wood** resonance of a double-bass or the body warmth of an **acoustic instrument** — come through clearly instead of being lost. For players using Realist or similar upright-bass pickups, this makes a big difference, especially on stage. The custom unit shown here combines a **10MΩ** piezo buffer with a **variable high-pass filter** (**20–200 Hz**). The buffer keeps the tone **natural** and open, while the HPF lets you control low-end boom and stage rumble — a common challenge with double-bass. This allows you to keep the fundamental notes strong while tightening the low end and **avoiding feedback**. Whether you’re going straight into an amp, DI, or pedalboard, a good piezo buffer is one of the easiest ways to improve **clarity** , **consistency** , and playability with any **acoustic** or upright-bass pickup.

If you play **double bass** , **cello** , **acoustic guitar**  or any other instrument with a **piezo pickup** , you know the struggle: sometimes you plug in, and the sound is thin, "quacky," or brittle. Other times, the low end is so boomy it causes feedback instantly. Often, musicians that use such instruments, especially bass players come to me with this exact issue using various pickups _(such as Realist, K &K, Underwood, JourneyTek, Vic's pickups, etc). _While they loved the natural character of the pickup they also felt they were losing the deep, warm body of the instrument when plugging into standard amps. **[The Solution: The 10M Buffer]** The culprit is usually Impedance Mismatch. Most guitar/bass amps and mixers have an input impedance that is too low for a piezo sensor (usually around 1MΩ). This "chokes" the signal, killing various frequencies. For such cases, I usually design a custom **High-Impedance Buffer** (**10MΩ**) that may include additional features, depending on the instrument, the pickup type and the musicians needs. Think of this as opening a wide gate for your signal. By raising the impedance to 10 Mega-Ohms, the pickup can "breathe," restoring the full, rich tone that the instrument actually produces acoustically. **[A 'secret' Weapon: The Variable HPF]** Restoring the bass is great, but on a big instrument like a double bass, it can sometimes be too much, especially on a hollow stage or in a boomy room. That’s why, when needed I pair the buffer with a Variable High-Pass Filter (HPF), adjustable from 20Hz to 200Hz. It lets you choose a cutoff frequency anywhere between 200Hz and 20Hz through a single control knob, making it ideal for removing unwanted low-end frequencies that can cause feedback, boominess, or excessive sub-bass. **[Conclusion]** The result? A signal chain that keeps the "wood" in the tone without the "mud" in the mix. If you are struggling with your acoustic tone, you might not need a new pickup—you might just need the right buffer. **Feel free to reach out via thecontact form if you need a custom solution for your acoustic rig!**

--- _Photo byKen Barton on Unsplash _ **A Practical Approach to Vocal EQ in 10 steps** Because every voice is different, there are no universal EQ presets that guarantee great results. The most reliable method is to start neutral, listen critically, and make adjustments based on what you hear. The steps below outline a solid workflow for shaping vocal tone effectively. **_Steps:_** **1.** Start with a flat EQ curve. Do not rely on any EQ preset or curve you found online. Always remember that sometimes a non-flat response may already exist due to mic characteristics and its inherent tonal coloration. **2.**  **[Low Cut <60Hz]** Roll off the low end as it typically doesn't hold any useful vocal content. Instead, it can contain unwanted rumble, mic stand noise etc. In some cases, you might find it useful to rise the cut-off frequency up to 90Hz. **3.** **[120Hz]**  Boosting around 120Hz reinforces low-mid energy, may ad warmth but may cause boominess if boosted too much. Cutting it reduces low-mid body and can make the voice sound thin, even too thin if overdone. **4.  [300-600Hz]** Boosting this area may cause boxiness**(*)** , especially in booth recordings. A subtle cut in this region usually mitigates the issue. **(*)  **_Audio engineers often use the term “boxy” to describe a vocal or instrument tone that has an exaggerated midrange resonance, typically in the 300–600 Hz region. It sounds as if the audio is coming from inside a small wooden box—(sometimes dull, hollow, congested, and lacking clarity.)_ _ _ **5.  [1-2kHz]** Usually a slight cut here is helpful, since boosting can make vocals sound nasal. Depending on the nature of the singer's voice and the mic choice you'll have to fine tune this area accordingly. Boosting too much can make vocals harsh rather than just nasal. **6.**  **[4kHz]**  This area is more commonly associated with **presence** and aggressiveness. While nasal overtones in this region are less universal, subtly cutting 4kHz may reduce harshness or glare, not just nasality. If, after cutting slightly the 1-2kHz range, you still notice nasal overtones, try a subtle cut on the 4kHz area as well. **7.**  **[5kHz]** Boosting around 5kHz enhances vocal presence and brings the voice forward in the mix, especially if the recording is already dull; however, _be cautious_ as it can amplify sibilance _(**"S"** and **"T"** sounds)_ and make everything more _"hissy"_. A subtle cut in this region can reduce harshness while maintaining clarity, particularly useful if the vocal sounds too bright or fatiguing to the ear. **8. [6–8 kHz]** This range adds clarity, definition, and intelligibility to the vocal, helping consonants and articulation "cut through" the mix. Boosting can make the vocal more present and detailed, but excessive boosts may accentuate sibilance and create a harsh, edgy, or fatiguing tone. A subtle cut can tame harshness without dulling overall brightness. If sibilance persists after adjusting 5 kHz, use gentle EQ adjustments in this band instead. **9.****[8–12kHz]** Boosting this range enhances brightness, clarity, and the perception of detail. Over-boosting can lead to exaggerated brittleness, or a hyper-detailed sound. Cutting this range reduces high-end sharpness but may dull the vocal if overdone.** ** ** ** **10. [12–16kHz] **Often called “air” range. Boosting this range adds airiness, openness, and a sense of space. Too much boost can create an unnatural, hyped top end or introduce hiss from the recording environment. Cutting this area is rarely necessary unless correcting harsh, overly bright recordings. **_General advice:_** Always EQ while listening in context with the mix, not soloed, for best results. This avoids the common trap of over-EQing isolated vocals. _**_Important Note:_** The frequency ranges and suggestions outlined in this guide are starting points, not absolutes. Every microphone has its own tonal character, and every voice is unique—shaped by gender, age, tone, and technique. Use these steps as a framework to train your ear, then adapt based on what you actually hear. Trust your listening judgment over any preset frequency. _

**2-mono inputs, mixed down to a single output.** This **compact mixer** combines **two mono** (TS) input signals into a single mono (TS) output.

There are countless **expression pedals** in the market and if you take the time to check the specifications that each manufacturer gives for their own model you will see that there a differencies. One of the most important **specifications** you must check before buying (or building) an expression pedal is what many manufacturers call the **"polarity"**. The term in our case is obviously not referring to a voltage but to the way the output of the expression pedal is**wired** to the internal potentiometer. On the left we've marked the **3 ways** an expression pedal is usually wired. You will often see those three "polarities" marked as **TRS** , **RTS** and **TS**. - DIY Tips -

**2N5458** is a quite common JFET transistor for audio applications, pedals, pre-amps etc.  (datasheet by on-semi)  On the image you can find two simple applications: **i)** a buffer _(e.g. before a tone-stack)_ **ii)** a pre-amp/boost The component values are real and both circuits can be used as is. The boost circuit can be stacked with another similar stage to increase the gain, just make sure you use the correct type of output capacitors for both stages. Adding a 100μF capacitor in parallel with the source resistor of the 1st stage will also give you increased gain and might overdrive the 2nd stage producing some smooth clipping, but it definitely depends on the level of the input signal. - DIY Tips -

**Active, DC Coupled Matrix Mixer 12x12,  **for mixing Control Voltages & Audio **** The device’s inputs & outputs are **DC-coupled** and can be used for **Audio** and **Control Voltage** mixing. The circuit is designed in a such a way so that it actively **rejects** the **crosstalk** among all inputs & outputs. It is suitable for**instruments** _(guitar, bass, etc)_ , **synths** , **eurorack** signals and any kind of **line level** signals. All **volume pots** behave in a regular fashion, that is when the knob is fully counter-clockwise, no signal from the associated input passes into the mix. As the knob is advanced clockwise, a greater portion of the signal passes into the mix. (At max position there is unity gain.) The mixer works with standard **9V** pedal power supply which internally is converted to **dual rail supply** (**-15** V,**0** ,**+15** V) in order to achieve greater stability and maximum headroom for the ICs inside. _IMPORTANT NOTE:_ _When mixing multiple audio or CV signals you have to take into consideration the level of each signal you route to the inputs and set each knob to the appropriate level in order to keep everything inside the headroom span and avoid distortion. The device can easily handle signals that are at line level or much higher but since all inputs are DC coupled extra attention is required when summing multiple signals from different sources._ _Specifications:_ ▹ TS 6,35mm inputs & outputs ▹ Input impedance: 1MΩ ▹ Output impedance: 330Ω ▹ Required power supply: 9Volt DC, Polarity: center negative ▹ Current draw: 500mA ▹ Weight: 2.28 kg ▹ Enclosure Dimensions: 275x173x65mm (10.82'' x 6.81'' x 2,56'') ▻ AC Coupled Matrix Mixer 4x4 ▻ KRAMA-3 Triple Loop parallel blender ▻ Stereo Pedal Mixer ***/* I don't keep stock of this mixer.
