hurm. i don't really get any hiss with my Rusty. i use it as a pre for a power amp, not as a distortion pedal, and i get a big bump in lows if i turn up the low knob. i keep mine pretty much 50% across the eq knobs, gain at 40%-50%, volume all the way up.
i get staticky hiss if i mess with the gain knob while it's going into an amp, but that's inherent in the design.
Yeah the gain knob static freaked me out until Tronographic told me it was normal.. fiddling with the knobs while plugged in made it hard to ignore.. I really miss my Rusty Box.
I didn't experience any hiss while using it as a preamp OR distortion pedal. Then again, I wasn't running any of the knobs full-on, I spent most of what little time I had with the thing trying to tame it, reel it in.. 'twas a quite loud little beast!
NOW I WANT ANOTHER ONE! Thanks, guys, really.

( I go there like every week! I need to stop. )
