I have just got a second hand Joe Bonamassa wah, and noticed a small capacitor across lugs 1 and 3 of the wah pot. I’ve never seen this before, either in images or schematic for this wah or any other wah, and it looks like a modification, not from the factory. The sweep had some crackle so I...

I’ve recently got a Quecoo T12-956 soldering station to replace the most basic of basic soldering irons I’ve been using, an Antex C15. The Antex has served me well but ever since watching a video by Marcus Reeves on tools for pedal building, in which he said he was using a Quecoo in preference...

Has anyone else bought a Hammond 1590N only to discover it wasn’t what you were expecting? The damn thing has ribs! I ordered three of them, the one I wanted, and had obviously bought before, was a 1590N1. I had no idea there was this other version! Thankfully I can just slide a piece of paper...

I have “insufficient privileges to reply” to post on the original Sola Sound Yellow Hybrid Tone Bender thread where the circuit was traced, but I noticed that the tone pot on that version was a W20K, It looks like they have also used a B22K, well on a later version at any rate. I notice that...

I’m getting myself in a mess because I don’t know how to do the calculations! This circuit is Spaceman Effects Charon, traced by Deadend FX. I’ve bread boarded it and think the fuzz is quite appealing, but I feel the tone control does nothing, it is supposed to cut bass as you turn it clockwise...

I got these ’smart’ tweezers just before Christmas and I wish I’d got them a lot sooner. I predominantly use them to check component values before stuffing them in to a PCB or bread board, and they save a lot of time when resorting all the components once I’ve pulled the bread board apart...

I had the opportunity to play my mate’s Rattler V2, and thought the boost was a very nice addition, once we’d taken it down from it’s default maximum. As far as I know it’s not been traced and I thought it might be a bit of fun to bread board a circuit that might give a close approximation of...

I’ve become a bit fixated on the idea of a tube OD/preamp pedal build, the ‘Son of Ben’ is my current OD of choice and having built and tweaked my own SE valve (sorry I’m British) amp, I’d like to tinker again! What I’d like to find is a schematic or PCB for a universal power supply to do the...

I'm trying to track down a v1.7 and or v1.4 OCD schematic. I'd like to breadboard it over the weekend to see if it's something I need! Did Pedal PCB do an older version of the ADHD? Funny I should be looking for this today, but it has nothing to do with the news from Fulltone, It was watching...

Having breadboarded the Golden Fleece over a year ago I eventually made my own board, it ended up as a test bed for a new etching rocker system!
 
 The original thread for the Golden Fleece is here: https://forum.pedalpcb.com/threads/mythos-golden-fleece-fuzz.4202/ I've used a 100pf for C6...

My pedal building has slowed down somewhat, a consequence of lack of parts, costs going up and playing more guitar! But a new Epiphone Les Paul was a good excuse for a treble booster in the form of ROG Omega, which is a FET based, so not traditional at all. I’m still finding my way with it, but...

I've just got 20 1T308B and they all display the diode symbol between the collector and emitter with a forward voltage around 4v on my component tester. I'm new to Ge transistors so it could well be normal for them, but if anyone can shed some light on what it means I would be grateful. My plan...

I have two bags of GL5516 LDRs bought from two different suppliers on ebay, using my multimeter and shoving the LDR in a dark drawer I'm getting a reading of about 4M ohms from one lot and 6M ohms from the other. KE-10720 LDRs seem to be beyond the measuring capability of my multimeter. Using...

I know it's not been released yet, but can this be easily modded to have a level control like the CE2B? I think it's just a variable resister between the effect and the input of the output half of the opamp. https://www.pedalpcb.com/product/pcb416/

I know there is some info in another thread, but it would be helpful if this and the other 'Boneyard' editions had a bit of info to help make the decision as to which version to build. First, are there any tonal differences? I can see the the output section is been fed off the opamp not the...

The Southern Belle is a variant of the the Mach 1 and as such they are very similar, and if my understanding is correct, compared to the Mach 1 the Southern Belle has a gain boost in the feedback loop of the first half opamp, hard clipping diodes and more gain in the feedback loop of the second...

Are there any harmonic tremolos plans in the pipeline? Preferable switchable between normal and harmonic modes and analogue in nature.

I’m looking at the various blues breaker inspired circuits, and I’m confused, the inverting I/P (pin 2) on the IC is sometimes, via a resistor and capacitor, referencing ground and other times Vref. Referenced to ground on: Parthenon Paragon Overdrive And the Vref on Blue Breaker Glory...

Hello, I'm beginning to get the itch to play some bass guitar and was wondering if anyone could recommend any pedal builds, I've only discovered the Obsidius Preamp so far. It would be great if there were a bass category on the left hand side.

Hello, has anyone built both the MOSFET Driver and the Cattle Driver and compared the two? Also, is the MOSFET Driver PedalPCB's own development of the Tube Driver? Not that I'm going through a Pink Floyd phase at the moment ;)
