So I was building a vero Orange Squeezer to bass specs, fired it up, worked like a charm, started noodling away when I get that all too familiar burning component smell.  Touched the IC and the transistor, nothing, figure I'm imagining it or having a stroke, keep playing, only to see the sustain pot (wired up externally) starting to glow red hot and smoke.  Needless to say, it got a quick bath in the toilet, and a new build will be started off a different layout, as I suspect it was missing a ground on the layout I was working off of.  Made for a fun New Years Eve.

Wow, now that is something I've never seen! A glowing red pot.

Or, maybe I have...in my college years.

Exploded a cap (they let go with a BANG), but never made anything glow (that wasn't meant to). Impressive!

It has happened to me too!! I was testing a Standard Fuzz build last year (I mean 2011!  ;D) and the pot was sorting with the 9V supply. Not only glowing red, but smoking too!  :D

Did it produce nice warm tones?

Oddly enough, it did produce nice warm tones.  If I could control the burn, I'd market it as "One Smokin' Hot Compressor".  Terrible joke, I know.  Funny thing was, it didn't start smoking until 80% rotation, so theoretically I could control it with a resistor in series....

Chances are your FET was in backwards. I've burned up at least one trimpot by putting Q1 in the wrong way.

The pedal might actually be fine; I'd at least try fixing it first.

You wouldn't have to mount an indicator LED!  ;)

Market it as a stoner rock pedal.

Aren't they all??? 8)
Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.
