I can't get a clear download; got a better Pic? Or is it too soon?:unsure:

May be the viewing angle in the pic, but is the input jack "tip" lug touching the power jack nut? Would the "out" jack tip contact the power jack ground lug if a plug was inserted?

Yes, you can.

It's straight out of the datasheets. Can't remember which one, but it's not a proprietary thing..

The schematic suggests the order is: Ringer > Bender > Muff. A cursory glance at the circuit traces seems to agree.

College? Night school? Barring those 2, it just takes time, soak up everything you can!! Oh, and learn to love math!

Yes! Thank you! Can't wait for pt. 6! 💋🤌

Your diodes are probably fine. Leakage is part of the "mojo" of germanium diodes, and can mess with your measurements. As long as they conduct one direction and not in the other, they're (y)...

Are you using the same type LEDs in them all? Pull one leg of the LED and see if it changes the pop..

What drove the choice to use the LM358?

yes! That would lower the total available gain, R7 to 10k would be a great starting point!(y):geek:

Changing "drive" to 1M will not give less distortion. It will allow MORE total distortion. I would try changing D1 and D2 to LED's, or going with 2 x 4148 in series, both directions. If that's not enough, ditch the diodes completely. The caps you point out are part of the filtering, cutting out...

I was just making a dumb joke, changing contacts around shouldn't affect anything, I was really wondering more about the specific design choice!(y) I used v1.1 schematic BTW..

I built a few boards using this schematic, (after paneling I got 15 pcb's inside 100mm x 100mm.. 60 boards for 2 dollars and shipping at JLCPCB!) I changed the contacts on my schematic after noticing the on-at-power up design. I was wondering if there was a reason to do it that way... P.S. I...

This looks very interesting! Sooo crying out for some mods. U1A is begging for some filters, and maybe a muff tone stack after the diode, kick the gain up on U1B? 🤟

R5 and C2 form a low pass filter. R5, among other things, works with C2 to set a corner frequency and helps set AC current.

1. Yup, leave out c16. Jamie Stillman is the only one that can answer why he chose that. There is no tech reason, other than It does change the sound slightly. 2. Yes, on the schematic. Electrically, there is no "left" or "right". 3. Everybody else does it! Go for it!

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.
