    DEMO I had no idea what I wanted to do and it sounds like a sick, horny cat.

    Im calling the cops on that enclosure, lmao

    De-soldered Parentheses Fuzz PCB - Is this OK to redo?

    Yeah that's what I mean!

    De-soldered Parentheses Fuzz PCB - Is this OK to redo?

    Correct me if I'm wrong but doesn't it seem like everyone who posts about it says they put the rotary on backwards at first :LOL: I know I sure did.

    Parentheses Fuzz

    How did you do the enclosure graphics? Looks amazing - I should really add an expression control to mine...

    TPA3118 60W Power Amp Module

    Been following this thread for a while so I thought I would post my test results as well! I decided to go full-bore and make a little amp in the box with the PedalPCB Valhalla Distortion (based off the Diezel VH4 preamp pedal). Took a few days and a lot of planning - I added a switchable FX...

    SOLVED Isosceles Boost Issues: tiny/no signal when engaged?

    Thanks for replying Giovanni! In fact, I figured out the problem this morning and the exact same thinking lead me to the issue. In my original post I said the signal at max volume was tiny but sounded "a lot like a gated fuzz / spitty / etc." and I'm pretty sure it's because of exactly what you...

    SOLVED Isosceles Boost Issues: tiny/no signal when engaged?

    I am able to measure the IC pins on a working Isosceles: The main difference is pin 2 (IN-) and 6(OUT) of the TL072. On the working pedal, pin 2 is 29.2v and pin 6 is 20v. On the non-working one pin 2 is 6.92v and pin 6 is 32v! It's a similar story on the transistor: working is C: 29v B: 26v...

    SOLVED Isosceles Boost Issues: tiny/no signal when engaged?

    Not sure if it will help, doesn't seem to be much interest in this thread but I'm hoping it helps someone. Here are some measurements between a working and not-working circuit... I'm currently trying to think of a scenario that would cause the voltage to be so low on the other side of the...

    SOLVED Isosceles Boost Issues: tiny/no signal when engaged?

    TAKE MY ARM!!! WE SUFFER.....AS ONE! ... I haven't fixed it, but I built an audio probe and damn I wish I made this a day ago. Let me get you a link. It absolutely changed the game when it came to diagnosing the issue and would've saved me so much time if I had made it a few days ago. I just...

    SOLVED Isosceles Boost Issues: tiny/no signal when engaged?

    Interesting find: if I suspend SW1 in the in-between state, aka, I get it right in the middle where only the center lug is active, I get signal + working level knob. If I switch it up or down per normal, I get nothing. I think I've traced this whole circuit for continuity and everything is right...

    Hey thanks for the reply. Sorry I'm just getting to it. For the TC1044SCPA: http://ww1.microchip.com/downloads/en/devicedoc/21348a.pdf (left side, top to bottom) 1. 9.50v 2. 4.86v 3. 0v 4. 0.13v (right side, bottom to top) 5. 0v 6. 4.72v 7. 6.08v 8. 9.50 For the TL071...

    SOLVED Isosceles Boost Issues: tiny/no signal when engaged?

    Hey all! I am having some trouble with an Isosceles Boost build. This isn't my first pedal or even my first Isosceles. Pedal "works", but output is very quiet unless you play really hard, in which case the little bit of sound that comes out sounds a lot like a gated fuzz / spitty / etc. Things...
