Okay, bumping this back up. I can hear flanging, but it’s distorted (hasn’t been calibrated). If I short out r22 (22k which feeds into the gate), I get sound and passes through. Voltages seem to hover at all pins of the FET (J113) about 6.5-7.0V. The 1M that connects the drain and source...

I don’t have a picture currently, but I smashed a red llama and a tubescreamer with a 6 way rotary diode selector + series/parallel switch (works-ish) in a 1590DD. The tubescreamer boosting the red llama sounds really good. PS you don’t want sound clips from me. I don’t just stink at playing: I...

From what I’ve read, yes. That site you download the “patches” and then you’ll need a way to put them on an EEPROM via a programmer. I think I got it right, based on what I’ve read.

I usually get hung up on builds because I’m a dingus and forget a part. (looking at you TL071 I forgot to order).

Well, if you don’t want it, I’ll take it off your hands. :) But yeah, Hydra/Arachnid. Link to a major library of fv-1 patches: Patches

Darn you two, now I want to find a way to build a guitar with Zcoils. (Mumbles incoherently while getting back to the ginormous backlog of pedals)

Usually I can troubleshoot okay-ish, and have a Flange with No Name board working, but this one is stumping me. I’ve ran an audio probe through the circuit: step 1, passes through with bypass off. step 2, I lose audio in the circuit. My goal was to make sure the audio portion worked before...

Thanks. I’ll see what I can dig up

I can usually ID where PCBs come from, but this one has me stumped. Any directions where to look? Thanks (I did try the number but nope)

Mmm, aged carbon film. Because you need the extra white noise when plugging in.

If you ignore the bad wiring, it works based on a series/parallel switch from a Marshall JTM clone I built a while back. Only issue is that it will oscillate when it’s in parallel and I think the tube screamer is turned on. So that may be a flaw of my wiring.

I built this at home withal a series/parallel switch I borrowed from an amp. But I don’t have it now: I’ll put it up when I get home

I missed the asterisk on the schematic! D’oh

I’m stumped, but vested in helping. That Q3 negative voltage is making me question what’s going on. Maybe try a new cap that lead to the 100k resistor. [edit: try the cap from your board in the breadboard first - it will change the voltages if it’s bad in your working verision]Also, did you pull...

do you have an audio probe?

Those enclosures are awesome

Weird question: is your power supply good? I’ve had a couple pedals act weird with a sketchy power supply. (Really, I’m just spitballing some ideas)

R9 biases Q2, at least based on my fuzz face knowledge. Just throwing ideas

Do you have the right resistors for biasing the transistors? Ie Are they the correct value? It really sounds like a bias issue on the transistor(s). Give the voltages a check and see - it will definitely help solve the puzzle.
