I'm hunting for the R2 schematic or a reasonably priced used R2 I can trace myself... Thanks.

I screwed up the thread title. Meant to say "... at PCBWay.com" In order to embed reverb into a combo pedal, I've made a PCB in small format. My intent is to install an always-on reverb into a combo pedal and use trim pots to "set it and forget it." Here's one with alpha pots used for testing...

I've gotten my FV1-Dev board working. But the software suggested by the wiki will not display correctly. It looks like this for me and I've tried all the compatibility mode crap to get it to display and it just won't. It works (after I found the right drivers online) but this bothers me too...

I just saw a post over on the gear page about folks blowing up their KTR by applying 18V accidentally. IMO, pedal makers should expect such a thing to happen and handle it gracefully. The common voltage doubler chips have a max operating voltage of 10V. Pedals that use them usually have a zener...

Since I already typed this out for someone asking how to use my soft-touch code, figured I could post it public. This is for Arduino and ATtiny (or Digispark, Olimexino, etc...). Download and install Arduino from here: https://www.arduino.cc/en/software Run Arduino IDE. Go to File |...

I've spent an inordinate amount of time creating a combo build with 3 footswitches in a 1590DD case. The picture tells most of the story. I'm happy to share info about it if anyone is interested... I'm wondering if anyone else has any interest in such a thing.... To make this all fit, I had to...

Not sure if this is already known or not but internal to the 2n7000 mosfet is a zener diode from source to drain to protect against over-voltage spikes or ESD events. I see the ADHD (and OCD) are trying to use the mosfets in a diode connection as if the clipping voltage is set by the mosfet...

Any interest here in a mini-pedal DIY platform? I found an existing mini-pedal that is already a decent DIY platform, using two PCBs. It has a bottom board with I/O jacks, true-bypass footswitch, 9V and Vref supply, LED support, and an emitter-follower buffer on the input signal prior to sending...
