It sounds nice - pretty subtle distortion. Not much boost, though, which is a little disappointing since I was hoping to use it in front of my little "tonemonster" frankenstein amp or maybe the little Magnatone.
While I was working on his amp, I lent him this little combo, which is made from an old record player amp and a weird speaker cabinet I found:
I added a nice vintage Alnico 8 inch speaker and a piece of burgundy-and-gold grill cloth in the hole. It's got a nice tone, not very much volume, though. I like the shape of this speaker, and might try to build an amp from the ground up using this design.
I also have been playing through a Bogen CHA-20 PA head using the mic input, and it sounds very nice.
I started assembling my "Tweak-O" fuzz pedal kit last night. Excellent instructions and no glitches so far.
