    Help identifying this schematic symbol/part?

    Thank you. Yeah, I’m not gonna mess with those unless I have at least grounds for suspicion that they are the problem. Interestingly, about a year before I started on this pedal building journey, I did some preliminary investigation to see what might be up with this pedal. At the time, I was...

    Help identifying this schematic symbol/part?

    Working on trying to revive an old Digitech pedal (to the extent I can within my abilities). While it is 90% SMD (definitely beyond my abilities) the caps and certain other components are through hole. I suspect that the problem is that someone plugged the pedal into the wrong power supply so...

    PCBGM Electric Lover not passing signal

    Have you seen this thread from a couple weeks ago?

    Kewpie Fuzz

    Definitely do that. On some of my early builds, my daughter either did or helped me out with the artwork (and, once in a blue moon from time to time now, she still does). The upshot is, even if I don’t end up liking the sound of the ultimate pedal or eventually build something else to replace...

    Wow, you are just knocking it out of the park with your graphic designs. That looks amazing! Mike

    Schu-Tone Boss DS-2

    I was very lucky to acquire a DS-2 board offered by @dan.schumaker in the trading forum. While I had used some Boss pedals in the past long ago (SD-1, OD-2 and CE-2), I’ve never played around with a DS-2, and the Nirvana connection intrigued me so I went for it. The build: it was a pretty...

    VHS -- aka Primary Colors

    That looks fantastic, and I really appreciate hearing the backstory and thought process that went into the whole thing. Mike

    ICL7660SCPAZ vs TC1044SCPA

    I generally try to use a 7660S whenever a schematic calls for a 1044 now because of prior times when using the 7660S cured charge pump whine that I was getting with a 1044.

    Angry Frog (Mean Green Metal Machine)

    That looks terrific! I'm glad people posting in this thread resurfaced it, as I hadn't seen it when it was originally posted. I use a lighted magnifying lens/ring as well. Interestingly, the issue it creates for me isn't one of depth perception - instead, it's that the light reflects so much...

    A few Tearjerker Mod questions

    I'm not so sure it doesn't have a gain control (this is frankly why I find this build so confusing to calibrate - the "names" of the trimpots don't seem to necessarily follow their function). So I snipped the following from a post Robert made a while back and keep it on my phone so I have a...

    A few Tearjerker Mod questions

    Thanks! That face plate actually came with the enclosure. The enclosure was originally a Mission expression pedal, which I gutted to use for my wah build.

    Tearjerker - post your settings

    The Tearjerker was the second or third pedal I ever built about a year ago, and I built it mainly because I had never owned or played a wah before. Given that the Tearjerker is uber-customizable and contains four trim pots in addition to a set of DIP switches, and given my complete lack of...

    A few Tearjerker Mod questions

    Hi – when I built my Tearjerker, I put all the trim pots on the outside as well. The advice I received at the time was that trim pots are generally linear, and so a linear pot would be the usual replacement – but that you could always experiment with a different taper. I just went with linear...

    What's on the workbench?

    This is nice and all, but I fear that all of these side projects are getting in the way of you completing the work on the EQD Swiss Things, I'd kindly ask that you reexamine your priorities and, if necessary, any related life choices that brought you to this crossroads.

    This is on-point for a thread about an echo pedal. Well-played. :ROFLMAO:

    Cataclysm Delay

    This will probably be my last build for a little while. I find the process of building incredibly interesting and relaxing – but I’ve pretty much built everything I want or need right now (in fact, multiples of several of them). So I’m waiting until some of the upcoming projects Robert has...

    Tearjerker making oscillating sound

    Been there, done that. I built a Rangefinder (Rangemaster clone) that worked fine for seven or eight months and then developed a pronounced whine. I posted a troubleshooting thread here and did all kinds of stuff – replaced the wiring, replaced the filter cap, pulled the charge pump – nothing...

    Pumbaa Distortion issues (Thorpy Warthog)

    1. People are going to want to see a clear shot of the back of the board (to look for soldering issues, etc.). 2. I see the build document calls for red LEDs - that usually means diffused red LEDs. The ones you have look clear, which makes me think they may be more like those red waterclear...
