Maybe I am blind, but how are IC1 and IC2 biased? IIRC the original schem has them at bipolar 15V, but on the build docs they seem to be at 24V-gnd. I cannot see any Vref connection. Will it work as intended without a midpoint bias?
Thx in advance!

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...

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,...

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,

I have a reissue Fender Blender (corrected wiring and removed resistor to match the original per standard mods) and a PedalPCB Blender kit that both have the same issue: a constant loud hum that is masked when you hit a chord/note but which doesn't seem to actually ever go away. I just spoke to someone else with a reissue, and they said theirs also has the constant hum. But when I watch videos of the reissue online, they are seem to be silent.

I thought for sure the kit would not have the...

Hi all,
I am in need of some help here. I have built a Benzin VH4 from PCB Guitar Mania. The pedal is passing audio signal however it has no distortion (maybe a light overdrive). I have probed the pedal and it seems that audio is nice and full coming from IC1 (Pin 7) but is being cut before it enters IC2 because it is very weak coming out of IC2 Pin7. I also had a hunch that it could be a bad cap in that gain stage so I have swapped out C6,C7,C8 and C10. Is there something I'm missing???????...

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,

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 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.
