You will need to jumper the unused LED pad. You will still need a CLR, No matter which LED pad you choose. The CLR and the LED are both between +9v and the "SW" pad, so LED current cannot get to the footswitch if they are not populated or jumped.(y)

Voltage is normal. It has a charge pump making a bi -polar power supply, +17vdc and -17vdc, If you measure from ground. Between pins 4 and 8 on the op amp should be ~34vdc.

You'll have to jump the unused LED pad, as both are in circuit.

What are your pin voltages?

Trebuchet?

Wow! I'll bet you can find some HORRIBLE sounds in that..(y)

? At full CCW, the mosfet is set for unity gain. Am I missing something? It should be very close to unity as drawn..

VCC = Voltage of Common Collector

Yeah, it's a limiter. You can leave it out with no ill effects. Thorpy (among others) uses it in a few of his designs, as well.

It's hard to know exactly without the rest of the circuit, but in this configuration they form an over-voltage limiter.

I think it's a decent pedal! I'm the guy that just built a vero to try it, and it really solved a lot of little noises and signal issues live. Mind you, that's with a regular old bipolar power supply and not the "whatever" type..

You can also use solid wire, or cutoff lead ends..

That's how I'd do it.

Just lift one end of the resistor and run a switch..

Oh man if that gets ya, I know places on the web you can get the schematics AND a PCB, for like, less than 10 bucks! MOST have schematics, anyway.. 🤪

Have you continuity checked your toggle switches? Honestly, if your chip is coming on and affects the circuit, it's probably fine. IME, Cmos fails to silence. That said, I hope it is that easy to fix. The circuit is basically a 2 transistor "fuzz" into a blend circuit. The fuzzed signal is...

The vero "Underminer" I built sounds massive, and will never leave my board. It's a simple circuit, so I'd bet it's a soldering issue. Blend knob never cleans up completely, there's always a bit of octave, and the tone knob at center is "flat". CCW is darker, CW is brighter. Unity volume is a...

Is the "box" you have it in grounded? Unshielded wire will pick up any EMF in the area..

Opaque Amplifiers are MOJO🤌

In the case or the Brown Betty, the trimmers are for total gain. So there's no "recommended" setting. You put it where YOU like it, somewhere between "helluva lot of gain" and "way the hell too much" gain..
