I am troubleshooting this frost drive build and its confusing me. It has sound coming through but its weak and splutery (if thats a word). Then if I touch it with my finger on the back of the pcb in the area that I have pointed to in the photo it works as it should for 30 seconds or so. I think...

So I have a few pedals to trouble shoot... I'm new to audio probing, but I'm learning. If anyone can give me some tips that would be awesome, any knowledge and experience is welcome. Just wondering, sometimes the signal is weaker on one side of a resistor to another, is that just due to the...

Does anyone know what the potentiometer labels are for the Souldrive PCB, there aren't any build Docs?

Just finished a lone king, arrogantly thought I'd be sweet, it's such a basic circuit! However, when on output is lower than it should be, even when all the way up. It does sound like it should though, just a lot quieter. Pulled it out of the box and tried the audio probe and I pretty much...

Just finished another build and I have plugged it in to see how it goes and it's not good! Chauffeur passes sound when not on but high pitched squeal when on. I've never experienced this before. I love some input on how to trouble shoot this one.

I have just finished a duo phase, picture attached. The rate seems pretty fast, maybe slightly faster on one side than the other. Do the trimpots affect this? Or is there a mod that can be done to get a bit more range in the rate? It's wired stereo at the moment and seems to be just two...

Just finished this pedal but there is no phasing. Definitely sound, and there is a sound difference when the switches are flicked but no phase. I just read another post with the same problem but I'd love some eyes on it in case I missed something else. Here's what I've tried: Started with...

Hi all, Just building a duo phase and I have LDRs with the specs - 10-20k and 0.5M and 540nm. Firstly will these do, they are same specs as the ke 10720 that people seem to have used? Also the main question is that the build docs say to use a yellow led which has a wavelength of 575-595nm...

This is my first stereo effect, and I'm just curious to know if i need to isolate the two groups of LED's and LDR's from each other with something dark? Usually I can find a build report of one done by someone a lot smarter than me but I can't seem to find one.

I am reasonably new to this and for my latest builds I have started testing components more stringently. Most of my components have come from Tayda and I am finding that a lot of the components are not within tolerances. Metal film resistors are not within 1% but seem close enough I think...

Hi Everybody, Just ordering some parts for some new builds, and I was wondering if the LDR's and LED's are the same for the pendulum as for the double? Also If anyone has a wiring diagram for the double pendulum mother/daughter board and stereo jacks that would be awesome. It's my first stereo...

Hi all, Probably a stupid question as the title thread, but I would love some suggestions. I have a friend who has asked me to build him a drive pedal. He has only been playing for a year or so, and I let him use a slightly modified (switch for bright and bass response) TS9 based pedal. Anyway...

Hi all, Just finished those pro-10, blue side works great, green side however has really low output and no gain really to speak of. There is some sound coming though but not much. When green and blue on together it drops everything down to green output. I'm baffled! I noticed someone else has...

I'm just about to build a pro-10 and noticed there is no docs, shouldnt bother me too much, I'm just not 100% sure what to do with the input output connections and which side of which 3PDT gets connected to the other if that makes sense. Can anyone direct me to another pedal build that is...

Hi all, I finished an Abyss yesterday and everything works and the pedal sounds great apart from this digital kind of twitching sound, almost in the background of the effect. It doesnt overpower the effect at all but it is definitely there. Also, probably not coincidentally I built another...

Hi Everyone, I am about to do my first board with SMD components. I have never done them before, they are OPA1678 which are SOIC 8 I think. I have these little adaptor boards that will convert them to DIP8. However, not super sure on how to solder the op amps. Is it just a case of be really...

Hi all, Just working on a duocast, I have sourced a transistor for the OC-71 position, accept I've never used on of these before and I don't know which way around it goes. There is a red dot on the side of it that looks like it's been drawn on. Photos attached, please help me! Also I'm having...

Just finished an M800 build, photos attached. I have sound pass through when the effect is not on, however when I turn the effect on I have no sound. Maybe a switch problem, I thought I had continuity in the right places? Also I can bias transistors 1, 2, 3 and 4 to within of 4.5V, however, not...

I've built a few drive pedals now, and I'm not brilliant with the theory side of things but I've noticed that some circuits have loads of electrolytic caps and some may only have 1 or 2. I know in a tube amp they filter the ripple out of the power supply, are they doing the same here and why the...

Hi everyone, I've just finished building a lead solder pedal. It was a pretty tight fit. The pedal works but the LED doesn't. I noticed the same issue with a thermionic I built, which is kinda same PCB pot layout. I have my LEDs in metal bezels, please correct me if I'm going down the wrong...
