Why not try the Source Audio OFD? Some great tube drives, low gain drive, distortion, and an epic fuzz section. I have a B3K and an OFD and as much as I love the B3K, the OFD has a loooot to offer. I can cop a Vintage Micro tube sound fairly easily on it, and the Octave Fuzz is worth the price of the pedal alone.
