The circuit has a low cut filter (R8&C5) at 1.5kHz, which is pretty high. This might contribute to the harsh high mids people are describing. You could try increasing C5 (or running another cap in parallel) and see if that helps balance it out.

That 0ohm resistor on the stomp… cool idea to avoid stripping a tiny wire

I bet you could mod the Magnetron project to have the exact same voicing as the seabed? I haven’t studied the schematics in detail enough to say for sure

yep that’s right!

If you remove the charge pump from socket, you can jumper pin5-3, and then you should be able to test the whole circuit (bypass and effect), all working at around 9V. It’ll sound fine, maybe get into a little op amp clipping with gain and/or treble cranked, but should still sound Klon-ish

Big Monk is killing it. I was about to say something similar, but with 47k/100k pot/47k. That would be more range, but big monks method of more fine tuning might work better. So play around with it. You could also try 75k/50k pot/75k. The idea is that at the center of the pot, it comes out to...

V=i*R (fundamental electronics formula, which here I=current. We know how much voltage drops across the led (forward voltage, so the remainder of the voltage will drop through the resistor (when current is flowing, as Robert said). So to find out the current, we do i=(Vin - Vled) / R Let’s...

It would be my preference if the clr was labeled as such o the pcb. Every pedalpcb board first thing I do is look through the build docs to figure out which 4k7 is the CLR so I don’t fill that in without noticing, since I also usually use a different value. But it’s probably a tradeoff for ease...

Hi, just to make sure, the Basic Relay Bypass (Latching) build docs say to use 78L09. But, I thought 78L09 was supposed to have a minimum 11V input. Is it the case that it still functions fine, just with an output slightly below 9V if we input 9V?

The pt2399 is a single repeat device. The feedback is achieved by sending some of the PT2399 output through the feedback pot, then ties in with the input. Somehow you’re losing that signal between the output and input, either it’s grounding accidentally or the connection is broken. That’s what I...

Several years ago I used the Tone God taptation kit (available on diy stomp boxes, or at least it was). I used the tagboard effects layout for it. The tap worked well, as far as I can remember. The modulation was a nice tonal addition to my deep blue delay build. I actually built the taptation...

Idk if I’d call the pantheon a PoT ripoff… more changes from PoT to Pantheon than from BB to PoT, (the way the high-gain switch works, type of diodes, the bass control circuit, the op amp boost at the end). They had a blog post when it came out explaining where it fit among different BB types...

I’ll push back on that just a bit, plenty of boutique-turned-big companies like Wampler, EQD, Walrus, do a number of original circuits, and I think are more above board about where there ‘inspired’ circuits come from. I’ll agree it’s not isolated to JHS, but I think it’s a fair critique with...

All those points have a resistance path to ground that should read when the pedal is un-powered. (0~100kohm, depending on pot position). Maybe you have a bad pot? Or damaged solder pads? I'd use the continuity (beep) setting on the multi-meter to make sure pot pins are connecting to the...

Ah series resistance, not rectangle! Just measure resistance from pin2 to C3(-), should be around 11k. The resistance to ground at those points you measure would depend on feedback pot position (the resistance between pin2 and gnd). You measured 38M? It should never be more than 100k (pot all...

The photo that shows clearance with the pcb avtuallylooks like there’s something out of focus bridging (could be the angle of the phot though), and I know you already tested with plastic barrier. It seems like somewhere in the feedback path is shorting to gnd. (That would also help explain the...

I don’t know from the picture which row is which (maybe I could tell if I look real close). I’d suggest follows the connection traces from the pot pins to surrounding components, and match it up the the schematic. You can do this visually just by looking at the pcb traces, or use a multimeter...

I didn’t remove anything from the rockman boards, I fired it up a few times with a simple one-spot wall watt without issue, and now it’s in the mail… so I hope it continues to work, but thanks for the heads up, I’ll let them know to reach out to me if they have any issues.

Got the boards from Amazon, and it worked perfectly according to the diagram @Cybercow shared (thanks!). I used a little jb weld to fix the boards in the housing and tied the wires into the connections in the battery spring board. I also sprayed a little contact cleaner in the switches, which...

Boneyard Delegate (improved eqd warden) would probably be a great choice for bass comp. Ovnilab blog rates the warden highly for bass.
