I build guitars and like to do weird mods. This is just really a thought cloud. Could I use the Box and All EQ with external pots as an onboard eq/volume? Basically pickups go to switch hot and ground to pcb and then out to the jack. There would then be 3 active eq tone knobs and a...

So this was a somewhat challenging build. It’s a very tight fit. There is no room to play with the stomp switches. I had to fill and De drill enclosure to get them in the correct spot. I also had to grind down the lip of the enclosure to get it to close around the jacks. I had...

Well hopefully my last question. I got the bias trim adjusted to a tad above 4v, but what is the function of the input trim? Does it just work tweek the gain? Is this just a bias by ear kind of thing? Does tweaking this affect the bias? Thanks!

No sound except if I turn it to bypass. I have The two LED switch lights are running. 9v at the power but zero volts at C1 R1 or R8. Makes me think I did something wrong with the stomp switches but not sure what it cloud be. Did I do something backwards or upside down? Shouldn’t I get...

Just looking to get smarter here. What is the purpose of the red diode in combo with the. BS170? Is this some sort of clipping before the opamp?

What is the orientation of the SMD adapter? The adapter is labeled but not the pcb, and shape is not a guide. Picture attached (It’s a 50/50 shot of being correct) Pic is of the acetylene overdrive. For future reference does this orientation hold true for all the other j201s boards from...

I just ordered this. Is there a particular voltage I am trying to bias to and if so is that on Q5? if so what pin? I see on the schematic 4.2-5v labled, 4v measured. Is 4v the goal? thanks

I am having trouble getting the solder out of the neg (-). Is the through hole above it also a negative and I can just use that?

This was my first test of the platform on new circuit. Circuit is not working, but neither is the bypass so it could also be the test platform. It’s not a pedalpcb circuit so there is no ground at the top of the board. I jumped the ground by connecting the ground at the bottom of the...

I have had dead circuits before but this one is a fist for me. I engage switch I do get LED. Sound does come through the circuit pretty much clean (nearly the same as bypass) but no delay or echo. When I crank level up all the way I can hear a faint hiss in the signal, but no delay. I almost...

1. Curious on rough ETA on next batch. (Ie is it safe to order components for it) 2. Is this batch updated for the Sea Machine: Remove C19. Connect a 10nF cap between pins 1 and 2 on IC4. A small MLCC on the back side is a clean way to do it mod I’m reading about on the forum? Thanks, Mike

Just wanted to check wiring on combining the breakout boards. (IO and 3PDT) From what I can gather from the forum and the documents it should look like this? No grounding for the jacks and power and ground to the board matching the + and - Thanks!

Sorry if this is a silly question, but what side are the jacks mounted on? The one that says battery or there one the one with a logo? Or does it make any difference? The jacks fit easily in both sides.
