The Aion has a 15k in series with each 50k trimmer, so the range of adjustment is more limited.

I pulled the transistor, will swap it out. Need to order some more though. Thanks.

I measure them all with a multimeter while I'm populating but I'll check.

Yeah the Draco calls for 50k trim pots.

Built an Aion Draco Dr Boogie clone. Only issue I ran into was biasing the 4th J201. I could only get it to 5.8v with the trimmer turned all the way up. The others all could easily get 4.5v. Any ideas on why this might be? My guess is a bad J201, possibly damaged by me during install? I...

I actually went back and added some resistors to make it mono and drop the headphone level to line level like I found in this circuit: https://electronics.stackexchange.com/questions/426624/converting-a-headphone-output-to-line-level Would be cool to build one with some switches to go from...

I built a quick and dirty docking station for my Fender Mustang Micro headphone amp from parts I had lying around. Basically turns it into a pedal. This lets me hook it up to a big powered speaker. Could probably hook it up to my amp as well but haven't tried that. A little worried about...

Hmm. Did you add an on/off LED as well? I believe that can cause popping. You can use some resistors and a capacitor to fix it: https://www.muzique.com/lab/led.htm

Is it possible to (easily) change the LED behavior on the Phase II? It seems like when the depth knob is all the way to the left the LED is half bright and increasing it makes it go up and down from there. Could it be set to start totally dimmed and then the Depth control changes the max...

Putting an LED in my 535Q wah was the first project I attempted. I followed this example, and did a pretty crappy job. https://www.thegearpage.net/board/index.php?threads/dunlop-535q-wah-led-mod.1168208/ As I got better I decided to clean it up and at the same time use the C-Buffer PCB to...

Finished up my Crunch Captain Deluxe. Couldn't think of a name I liked with Crunch in it, but the Crunchbox is based on the Guv'nor, so I thought The Cap'n would be fitting. I designed the graphics to look like that. I didn't change anything from the build doc except moving the LED location...

Built a Madbean Rough Cut compressor which is a copy of the Diamond Compressor. Only tricky thing is that it has some weird resistor values that are harder to find. It also uses a center detent pot for the tilt eq which is kind of cool. Other than that, pretty straightforward. Never really...

Let me know how it goes I'm currently building one of these.

The optocoupler is also providing variable resistance in that loop so you could play with that? But seems like a high resistance pot is a good place to start.

I I'd gladly sell it for $5000! Although you can just have the UV print template as well if you want.
