Aleph, what do you mean by 'relatively clean octave up'? Do you mean the Escebo, or a digital octave up? I've played with the FV-1 octave up (absolute value) which should be as clear of the rectify as it gets, and I found it pretty similar to the green ringer circuit. I haven't tried the...

An analog octave just rectifies the sound wave. As in, all the negative parts of the wave are reflected to be positive. So if you visualize a sine wave, it becomes a bouncing shape. This is a crude wave, but it’s double the frequency. The closer the input is to a simple sine wave (neck pickup...

nice thanks for the info. I think that tool would have saved me some debugging in the past.

A lot of guitar dirt circuits accentuate the mids. I think reasons include -Some guitar amps such as Fender black panel era have a midscoop in the Bass-Mid-Treble tone stack, so a TS or Klon can fill that back in -Mids are the frequency range that guitars most prominently fill in a mix, so...

Of course, just have the footswitch connect Attack2 with Attack 1. There will still be some delay from the 1k resistor, but it’ll be very small, probably unnoticable. It’s not good to ground pin6 of the pt2399 without some other countermeasures. If you really wanted No predelay, you could...

Belton designs are nice for light to medium reverb, I have a one built inside my valve jr amp head (1776 Effects rub-a-dub deluxe, now out of business). Might try the Gravitation at some point for the extra tone knobs. Specifically, I've preferred BTDR-3 over BTDR-2. Some people complain they...

Nice build. I've been using a combination of stainless steel pins and braid for clearing out holes, but then I never mastered the solder sucker. https://stompboxparts.com/tools-supplies/stainless-steel-desoldering-needles/ For what it's worth, I recently built this PCB and compared it to my...

This will probably only interest a small cross-section of people who are interested in FV-1 coding the FV-1 line by line, and who like making waveform signals in Microsoft excel. Let me know if I'm not alone in that cross-section... When I want to understand how a block of FV-1 code works...

Well that TS and SD-1 info checks out, here's a quick and dirty Spice I did worked off some other similar circuits I had already modeled. At Tone=50%, TS is indeed ~720 peak and SD1 is ~1k peak. I know tyou already posted graphs of both, but I wanted to see them side-by-side in the same...

Klon circuit is indeed good. You mentioned the SD-1 has a 1kHz mid hump, vs the 700 (or 720) on the TS. Is there some analysis that shows that? The thought the SD-1 was pretty similar. Same HPF on the clipping stage (720) and just a bit higher LPF before the tone stage (884 vs 723)...

The spacing on the tweakit looks like about 0.1”, not the 0.2” of the pot pins on the pcbs. So you’d have to bend the connector legs. Still very doable. If the spacing was wider you could use pin headers

Maybe that’d be a nice idea for a new pedalpcb utility board (pot->trimmer)

Oops my bad yeah the trimmit wouldn’t work for this exactly

Pedalpcb has a Trimmit board for this exact purpose ($0.50). I’ve also made similar board out of stripboard.

For reference, from any of the pedalpcb build docs

I think your 9V jack red (+) and black (-) are swapped. That is, assuming you're using center-negative 9V plug like all pedals. There's no protection diode so it's possible that the reverse voltage hook-up damaged the transistors or electrolytic caps. (I'm guessing not, but it's possible that...

I would go 1u MLCC also, I’ve found that sometimes E-caps can let a little DC voltage leak through. If this happens at this point in the circuit, then a little dc voltage builds up on the output and causes a pop when switching. Film works too, as mentioned. I haven’t had any issues I’ve...

don't know. You could export the SpinASM code and analyze it. It should have text commands for: WRAX DACL, 0 (which means write some signal to the Left Output (Digital->Analog Converter Left) (pin 28) WRAX DACR, 0 (which means write some signal to the Right Output (Digital->Analog Converter...

The dev board doesn’t tie L and R outputs together. R output is unconnected. Anyway, cool project, thanks for sharing

your diagram was not correct, it showed diodes connected in parallel, not series. Also, if it helps, pretend the A & K holes aren't there. they're just for convenience so the LED fits nicer. They function just like the outer holes.
