Resistors in opamps and noise design

12dB is nice!

+1 agree with Merlin. Guitars hum.

When you plug an electric guitar into a pedal, which has six strings-worth of large antenna-surface connected to a magnetic pick-up with very sensitive coils designed to detect every vibration of the strings but which also pick up any other stray electrical fields flying about just as effectively, the amount of background noise *in the actual input signal* is probably the most significant thing. After all, it's not like a guitar into an amp is absolutely silent until you touch a note. Mostly you have to keep a hand on the strings to ground the damn thing.
Guitars are noisy. In both a good way and a bad way. So I'm not going to sweat *too* much about a little bit of noise in a pedal.
