First build - Clock of tone 50 :noise help

[gdog]

Hey, I"m new to pedal building, and I just built this circuit. I love it. Only thing is it's got a higher noise floor than I would like. It's a hiss, that is constant, and doesn't change with turing the knobs. It's only when effect is engaged. Is there anything that would cause this, being that it's my "novice" work, or is this the nature of the circuit? Input/advice appreciated!


Thanks!

Just saw a video on hiss a couple of threads down. The same sound on those pedals is what I am hearing. So I guess it's a trannie thing.
