I'd leave them the same.

Here's the thread on DIYSB for reference.

You're correct.

Dead Astronaut on DIYSB did a bass preamp that's the same thing with scaled down Tonestack.

Nicely done! The layout looks great too.

However I would go with some metal pots, but that's only my opinion.

Metal...pot? Knob, maybe?  ???
Yep, knob, sorry.  :-[

I thought maybe there was some kind of unobtainium metal pot you were supposed to use with that diode.  ;D

You'd think you'd be happy with something fused to the fuser roller?

Just kidding, I know nothing about printers, but it sound terrible and my condolences. Surely there has to be some kind of warranty, it's only been 5 days.

Those 47u (IIRC) are DC blocking caps, so phantom power goes to your mic and not to the input of the INA217 (or anything else). Check out the datasheet for the INA217. The input voltage is something like +/-3 or 4V. If phantom power was getting to it, I wouldn't be happy. Same with almost any type of music equipment. Line level is typically 1V. Nothing would be happy with 47V! That's why you apply phantom power before the preamp and not after. I'm sure there a better way to say it, ah well.

^^^ in what scenarios would using two series resistors or two parallel caps (or their counterparts) not result in the desired resitance or capacitance?

Where is the quoted "burn it" coming from?

If you want to do phantom powered, you are going to have to provide the phantom supply prior to the effect. If this is what you want, it would almost (definitely) be easier (and more versatile) to build a mic preamp with the phantom power, then feed that to the delay. You cannot go mic -> delay -> preamp/phantom power as that will either not let power get to your mic or "burn it".

The INA217 data sheet circuit does allow for phantom power if that was what you're asking?

I think you will get best results building a small mic preamp into the pedal, then you can just bypass it when you want guitar. The INA217 makes a SUPER simple mic preamp and takes your balanced input to unbalanced (what you need). You'll have to mess with the gain to make it similar to a guitar input. If you don't want to fuss with power requirements, there are a number of simple opamp based mic preamps.

According the AMZ it is! I imagine a lot of people got their part of their start from AMZ's teat, so probably. I think warp would be an overarching term, in this case, referring to any kind of harmonic mixing. The OP's idea is just one way to achieve it.

That looks like an Osh board. How do you solder that? Flux and oven? Tiny minions?

Do yourself a favor and check out all his other works. Also wear a chin guard for all the jaw drops. Goes by cloudscapes on a lot of forums or Sonic Crayon.

I don't see any reason to connect the center and normally empty outer lugs together since you're getting the same exact function.  :o
