In the late 70's, B.K. Butler designed a pedal that had the warmth and smooth overdrive characteristics of a tube amp. Naturally, the only way to capture a true tube tone was with tubes, and thus the 911 Classic Tube Driver was created.
If you are looking for a smoother, blusier overdrive, check out the 903 Blue Tube. The Blue Tube has about half the gain of the Real Tube, with similar controls and EQ. The 903 is perfect for Blues or Classic Rock guitarists, as well as Bass and Keyboard players who want to warm up their tone.
