I have the Wet Bar (Ibanez MF-5) on my board now and really love it. I was contemplating designing a three band EQ version. I’m not sure how best to proceed, so, I thought I’d put it out there to some of you with more understanding than I have. My idea was to add a third gyrator for highs and...

Usually when an effect gives no sound engaged, it's the switch or a wiring problem. If that checks out: Use an audio probe and trace the signal through the clean path. You should get something even if the delay isn't working.

Just reiterating some of the earlier posts. Setting the BBD bias trimmer precisely will give you the maximum headroom at the 9V. If that doesnt get you enough then 18V should solve the problem. Would recommend using an 18V power supply and not try to add a charge pump. Those are tricky with...

After the pedal stopped working, were you able to use it (i.e., working again) in isolation? Asking because sometimes stacked PCBs come apart with use. I put foam to prevent this on pedals I sell or will be giging with. If not, maybe your power supply can't handle the current draw of all the...

I've mistakenly mixed up the input and output jacks when testing a pedal out of the box before. Could that have happened? This circuit has a clean trace all the way to the blend knob, so, you should here something unless there's a problem with that trace. You should make an audio probe and...

I like the Timmy for low gain

I have used about the same process you are discribing. I used a sander with 150 then 400, then hand sand with 1000 and 2000. I've also used buffing wheels in my drill press with polish compound to get a mirror finish. I think for etching just a quick hand sand with 400->1000>2000 would be...

GOTA build report is a great way to start the day :cool: Just ordered this one.

Man, that sounds sweet! Congrats.

I'd recommend hoarding these JFETs. They are needed in lots of circuits and will take effort to get replacements. If you have the building bug, you are definitely going to use them down the road.

What ICs do you have in IC1 and IC2?

I just bought a Voodoo Lab PP2 on CL. I wanted to verify that I understand the current draw limits correctly with a few questions: 1. If a pedal needs 400mA and the max output of the supply is 250mA, does the pedal just not work? If it does work, is there any danger to the pedal or will only...

The list is in this post: https://forum.pedalpcb.com/threads/bass-klon.24042/ I just used these for a Kliche Mini. The schematics/parts numbers matched up.

That looks great! Did you use regular waterslide or the no-film?

I was wondering I could sub the 10k volume pot with a higher value, like a 50k or 100k? It's a voltage divider with ground but I'm not sure what's going on with the resisters on the switch??

I'm building up a bass Klon using Chuck's mods: https://forum.pedalpcb.com/threads/bass-klon.24042/ I have a stash of Ge diodes to choose from. Came from a PIF I received last year. I'll probably sample a few in the circuit before committing, but wondered if there were any guidelines or...

Best way is to download the illustrator template from Tayda, it has the layers. You also need to install the Roland color swatch. Then copy your art from your AI file and paste it into the layers. For the white and gloss layer you need to change the colors in your art to the white/gloss...

Whoa, that's above and beyond. Thanks!

Was wondering if any particular Hfe for the 5088s was preferable in Q1-Q4? Any input appreciated 🤘

Very cool! What do the switches do?
