The FuzzBubble-45 is one of the most authentic pedals I have used. You can really get those old 60s and 70s 'tube amp breaking up' sounds even at low levels. I put this piece together today (just riffed away) with some Townsend stuff at the beginning and end with some Jimi stuff in the middle. Nothing else was used except an Egnater amp (clean channel) and a Schecter tele style guitar. And any feedback sounds are courtesy of the Vibesware Guitar Resonator (GR-1). I didn't even play around with the knobs that much, which allows quite a variety of tones, distortion and fuzz.
