Hi all. I am having some issues with my Wolfgang 61 build. I posted on Reddit and I'm trying to repost here for help. There's a video posted over there that clearly shows the issue:

TLDR:
L channel seems fine, R channel seems ok until input gets too hot and then sounds blown out. Overall both channels have a noticeable volume drop from clean.

Hi guys,

I'm corrently working on the Chopper Party Device:

I was wandering what are the 6 lugs connection points (A-0; B-0; C-0) on the PCB next to the Rate Pot of the Phaser and A-T; B-T; C-T) on the Tremolo side. Is this for a normal stereo jack socket to change the rate via expression pedal?

How do I connect the stereo jack? Where is sleeve/ground, ring abd tip?

Thanks in advance

Hi guys,

it's me again. Does anybody of you build the Fuzz Phase pedal:

I was wandering if there are Ge-Transistors (T1 - T8) in addition to Q1-Q4. There are no further informations in the instructions but the circuit and pcb says you will need 8 soviet Ge-trannies (7x MP37, 1x MP42).

Do I need specific hFE for this build so I have to select them?

Maybe sobody can help me because he / she already build this pedal.

The Death by Fuzz IV ( requires specific zener diode 1N5277B which is nearly impossible to find.
Does anybody has a european source or equivalent for this diode? Datasheet says voltage should be 160V with 500mW.

Thanks in advance

Hi all,

Newbie alarm, first post :)

I searched the web for some information but didn't find any build reports for the Vandal from Hell yet.

I ordered a kit of the Vandal from Hell kit from Musikding. The build document is here:

PCBGuitarMan posted a picture of the PCB here on FSB in '21:

In the above thread people wrote that they used their circuit with 12V or 18V power supplies, because the Randall circuit used 24V. But in the build doc of the Vandal from Hell it says 9V.

Also,...

I'm planing to build the Cornic Fuzz which actually is a clone of Pete Cornish NG-2:

Instructions and different sides say it's an si-ge-hybrid fuzz and you should use npn-ge tranis for q4 and q5.

Does anybody has an idea which one should be better than the bc549 / bc550 shown in the schematic?

Hi,

I got a kit for this pedal and started building. My PCB version is 1v1.
I noticed that there are two 1v1 version of the building docs, and they use different resistor values:
Glory Drive DLX 1v1 – Building Docs (16th February 2023)
Glory Drive DLX 1v1 – Building Docs (11th October 2022)

I would assume the most recent one to be correct, but just wanted to check, since my kit came with the resistors for the october 2022 version.

Thanks in advance.

Hi guys.

I'm planing to build the Shoeman Pedal from pcbguitarmania:

Before start building I've some questions concerning specific parts and wiring:

1. Do I need 4 normal 3PDT foot switches or should the Momentary Option fit better witch a non latching Momentary 3PDT?

2. Can I take a MBB 1P12T switch or a normal 1P12T fir Multiplyer and Devider Option?

3. What doeses the 2 Lugs on the PCB Clean and CV stand for? Are there extra inputs / outputs for this options? How is the wiring of CV...

Hey guys,

I need some help with biasing the transistors in this Build the Wolfgang 61. I adjusted the drain voltage to around 4,4-4,5V expect for Q11 because I only have a range of 9-6,5V? I’ve got some sound out of it but the volume was so low I had to crank the volume of my 120w stereo combo to like 7-8 to be able to hear it very quietly when I wanted to increase like postgain r for example it started to make weird sounds and would get loud as fuck also there wasn’t any real fx applied to...

Hi,

I build this pedal from PCB Guitar Mania and if I use it with a dirt pedal in the loop of the Terminator itself all works well.
However, when I try to use it in the Serial Effects send / return of my Amp the signal of the guitar is sent straight to the effects return, instead of the guitar out of the Noise Terminator.

Anyone experienced this problem?

Thanks, Ron

Hi all.

After some trouble with my build i found a small piece of wire (with help of a magnifying glass and some patience) which was connecting the leads of two resistors. I also found a lead where the isolation was defective and one could see the bare wire. But i'm pretty sure the wire was not touching anything.
So far so good.
It is still not working. The Problem i Have now is that as soon there is a plug in the output Jack, the tip connection goes to ground. Tested with the beeper from the...

Hi guys I bought the Appetite for Distortion pedal from PCB Guitar Mania but it's barely making any sound.

I put the red LED backwards (facing up instead of down) so i removed it and i struggle to put it back the right way. I dont think this affects the sound though.

When the pedal is off, the signal is passed through cleanly. When it's on, i can hear the distortion, but it's super low output signal, i can barely hear it. I don't know where i went wrong.

Your help would be appreciated....

Hello everybody.

Please excuse my english. It is not my motherlanguage. :-)

I already build a few pedals from pcbguitarmania and other sites. The only time i had to adjust something was when i build a phaser. In that case it was done by ear.

I`m not sure what to do with the three trimpots on the calvin vai.
How should that sound? Are there some voltages i should measure somewhere? Nothing about the pots in the building docs for that pedal.

Would someone be so kind and can advise on this?...

A and t working but when u engage b it buzzes loudly and very faint signal and cuts signal to output t I’ve already changed the jack to a new one any help appreciated

Have some spill over on channel b and boost not working on one side and led light stays on on boost

Hey all,

I ordered the PCB for the Dr Trebor this afternoon. Was going over the build sheet while getting parts together and noticed this lone pad7 (top right). I can't figure out what it's for - doesn't seem to be anything mentioned in the doc. Any ideas? I normally build on vero so this is a new experience for me. Thanks so much!

Hi, I'm a little bit stumped - I grabbed a Ghost Device PCB recently ( and built it the other day - however, there seems to be an issue where the output is drastically lower when engaged than when not engaged. Aside from that, I can hear the reverb, it seems to be working as expected (though I don't truly know, I've never heard one)

Swapped out the TL072s, PT2399, and the diode hoping it was something simple, but none had an effect. Doesn't seem to be any unnecessary grounds, bridges, or cold...

Hello everyone,

I‘m completely new to the pedal building game and I‘m having some start problems. I build the Sinner Bass Drive from PCB and it doesn‘t do ANYTHING. I was pretty confident that I soldered all the parts in their rightful places but maybe there‘s something I‘ve forgotten. How do I best go about finding the problem with such a project?
I‘ve attached some pictures, I would be very grateful for any help here.

Hello Pedal Builders,

I have build a Knight of Tone from PCB Guitar Mania which plays very well. Now the building docs recommend to try it without the Charge Pump if using it with a lot of overdrive.
The doc says there is a graphic which shows howto bypass the charge pump.
Unfortunately I‘m not able to find the required information or graphic.

Looking at the schematic, I’m wondering if I simply need to remove IC3 and that‘s it. Can somebody confirm that?

If I want to have it switchable how...

Hey everyone!

I built the Electric Lover project from Guitar PCB Mania. Its a modernized Electric Mistress clone. It is passing signal, but I cannot get it to bias up correctly. There is only a small range of the BIAS trimpot near max-clockwise position that allows signal to pass, regardless of the settings for the CLOCK, T1 (max feedback), and VOLUME trimpots. Here are the directions for the setup:

Set Clock and Bias in the middle, at 12 o’clock.
Set T1 and the Rate knob fully...

Is it possible to run the cloned centaur on 12V or 18V ?

When opening up the case of my MXR carbon copy the stomp switch fell apart. I replaced it but now the pedal does not pass signal. Well, actually you still can hear the pop being delayed when either the battery or input is plugged in with the pedal turned ON. There is no signal with switch in both positions otherwise.

I have soldering experience working on tube amps but little on pedals and PCB's. I wonder if I damaged the board or something? The original switch was a major pain to get out and...

Hello everyone! I recently purchased the Sun Beta Lead kit through Das Musikding. I've just finished assembling the pedal and I've noticed that I wired the DC Jack reverse. So I corrected the issue and the LED turns on but the pedal emits a continuous, very high pitched whistle and if tapped on the enclosure it makes a very loud pop through my amp. I don't know if some component failed or something else...I don't know what to do!

Hi all,

I recently purchased a Sunn beta lead kit (schematic pcb guitar mania here After soldering everything, I just have a huge hissing sound, sometimes with kind of distortion, but nothing else, the sound is pretty unstable and reacts really bad to any note I can play.

The circuit is built around a charge pump that is supposed to deliver -15/+15 from a LT1054, and this component is really overheating as soon as I plug the pedal.

I checked the current delivered after the charge pump and...

Hello! Longtime lurker, first time poster.

I recently built this pedal. All seems well but when I turn it on, I get a rhythmic clicking and the LED pulses at the same right. No signal is passed (though it passes freely when in bypass) and adjusting the rate knob does not alter the rate of the click/led. This seems like a very specific issue so I'm hoping there's *a* cause that somebody can direct me to?
