The input of the op amp acts as a buffer (high input impedance), so there’s not interaction with the pickups.

I haven’t broken anything yet… despite some awful loud howling sounds coming out of pedals during testing. I guess the main thing might be speakers, so I guess make sure you don’t have the amp up too loud while testing until you know it’s working normally? Reading some articles about buffers...

Having built both, the sweet honey sounds quite a bit different to me. But I think that’s mostly due to circuit. Should be able to do the main part of the circuit just like the honey bee, then make the last op amp a simple booster. I don’t know if there’s a similar sounding dual chip, might...

You can also do the Pythagorus (same pcb as D3lay and Daydream). And get a custom eeprom with digital, tape, and kaleidescope patches.

The daydream is really cool. But it is a different sound from standard delay. I think if you want a more standard delay sound, the DMD2 looks like a great option because you can go from digital delay sound to tape (with the modulation and filter knobs) Another option would be to build the...

I used a pair of Buck Boost DC converters recommended by cybercow. It’s not exactly true restoration, but it’s an option. https://forum.pedalpcb.com/threads/6v-power-check-my-circuit.16499/#post-193832

awesome! i love the offset 2 knobs look. Show the finished product too

by closer to Vcc do you mean closer to -9v on the collector? I found closer to -4.5v to have more headroom. On a trip so I won’t be able to mess with it for a few days

Hmm idk how that board works since there’s no docs. But since there’s no resistor on the stomp/led board, I guess you still need the resistor in R6 of the RangeFinder. But other than that I don’t know how it’s configured, you could put up pictures if you want me to try to trace the patterns to...

I would guess the main things is that R3 and C3 make a bass cut filter at 723hz. Increase C3 will lower that to allow more bass through.

Ah.. yeah that’s typically the resistor for the LED. My initial plan was to use a relay bypass pcb with a nice soft switch. My own pcb design that functions the same as the PPCB one, but fits 1590B a little better, and I wrote my own code for. But my relay pcb doesn’t have a protection diode...

The volume pot performs this same function already at the output. Basically, caps block DC voltage, but they aren’t perfect at it. So a little DC leaks through and can accumulate at the input pin. Then, when you switch the effect on/off, there is a jump in DC voltage. The bleed resistor from...

Nice. Couple of things stand out to me Transistors come in difference pinouts, and I don’t see a note about which transistor you’re using to be able to check those pins are connected right. You should be able to modify the pin spacing of the transistors in the software to line up with the...

Here's my Range Finder build. I love the 8-way switch to tune the filter. The stock RM cap (position 2 on this switch) is quite thin, and I haven't enjoyed it into dirt pedals, but I've like 3-4 more. 5-6 sound cool clean, not full range transparent but a warm mid-focused sound. Initially I...

I build 1590B with side jacks any time I can. I get the popularity of 125B with top but it’s just personal preference. The 1590B size looks “right” to me. The side jacks feel less crowded with the power. I even buy PPCB boards and use wire to attach the pots so I can shift the pcb up for 1590B...

Yep your threads were one of the inspirations I listed, good stuff. I like the idea of testing out how close to the sound of original analog bbd effects this type of method can achieve.

Sweet. Does R1A affect the EQ? Seems like it would just add some gain, and you could still have the fat sw just by switching C1. I also don’t find the BM to be my favorite, so maybe your take would hit the spot.

Sounds like other people have had volume increase so maybe it’s common within part tolerance. I don’t personally measure resistors when building either. Couldn’t hurt. I do usually look at the stripe code though I guess, it’s good practice learning the color code

All above are good ideas, I'd personally adjust R5 first. Although I am a little surprised, I've built this circuit a few times and never had a volume level increase. And mathmatically, it seems lik it should be very near unity. Did you make any value subs in your build?

I like to add soft clipping diodes on a switch (red or blue LED) to prevent op amp clipping. This has a way of tightening up or focusing the sound (op amp clipping sounds muddy to me). This is messing with a beloved circuit so put it on a switch h so you can compare to classic rat tones.
