A long search on the forums did not allow me to understand why the 10u electrolytic capacitors that connect to the bases of Q3 and Q4 have different polarities in schemes and layouts (Pedalpcb, Fuzzcentral, GuitarFXLayouts, Sabrotone, GGG, etc.). Madbean uses 1uf film and it confuses me even...

The bass version of the EHX Small Clone (EHX Bass Clone) has treble and bass controls. I can't find a schematic available for this pedal. Any ideas on how to implement these controls in Small Clone?

Electric Mistress is a project that is on my radar, but I would like to have a mix control. If I put a B50K potentiometer in series with the resistor R18 (10K), would I be able to control the amount of effect and dry?

Could anyone answer if it is possible to build just the Uni Vibe preamp section? I notice that there are outputs from this part of the circuit that could be disconnected, but I don't know how to do it, or even if I would need to change the value of some component.

This is a pedal that seems very interesting to me. I wanted to know if I use an A100K potentiometer for the volume, could I have some kind of problem with the operation of this circuit?

I built a Small Clone clone according to the tagboardeffects model and I did the mix modification, replacing the 20K and 22K resistors with a B50K potentiometer and it works. The only problem: there is a volume increase in the extreme dry/wet positions. Any suggestion? Replaced resistors are...

I have an 18V Echoplex preamp built by the Tagboardeffects layout and tried to tune it to the Clandestine Preamp settings. I made the following modifications: 1 - 20K trimpot instead of 22K resistor; 2 - On-off-on switch with 22n and 10n capacitors instead of 22n capacitor; 3 - 100K resistor...

There is a guide for building this pedal. Based on Orange Squeeze with many more controls. I don't know if there is a later version of the circuit. Details at: https://www.diystompboxes.com/smfforum/index.php?topic=102861.msg932503#msg932503

Would it be possible on a 125B?

Any possibility of having this circuit with PCB Mount Potentiometers and the octave switch on / off?

Hi, I know it's not a pedalpcb project, but I need help identifying the switch model that turns on / off the MXR Classic 108 fuzz pedal buffer. I'm adding some pictures, in case anyone can help.

I built an Omni cab sim and a Rog Tonemender with veroboard and I would like to build with Pedalpcb. I would very much like to have a Tonemender PCB to build as in the attached photo. The two pedals work very well together for playing in line. Would it be possible to produce this pcb? Note: I...

Zero information about this circuit. There is a blend (it could be derived from COB). I don't know if there's a transformer. Sounds good with wah or vibe. has anyone seen it internally? The only image I found.

Hi folks! I ask for help with the following question: I bought a vactrol on ebay to build a Compulator pedal, but the description on the component is VTL (it is not clear if it is the VTL5C10 or VTL5C1). Is there any way to know which component it is? Some way to measure? When I connect to a...

I built a Tonemender in veroboard, but I have a lot of noise. I would like to rebuild on a PCB and put it in the same box with Unicab.

I don't have a schematic, but I believe he needs the trimpots for J201.

I ask for help with my Compulator project: I bought some Chinese VTL5C10, but the only markup is VTL. How can I measure to know if I received C10 and not some other one?

no schematic found

I built the Deralier Overdrive and I think it has more noise than expected. It's more than a fuzz face or a zendrive, even with the pedal turned on alone directly on the amp. All Tayda components. Any suggestion?

I don't have a correct schematic to post here.
