John at Tomaszewicz Amps had a pair of pedal on display at the Austin Amp Show this past weekend – the T-Drive and an unnamed, black-box prototype overdrive. The T-Drive is loosely based around the tone stack of the original BK Butler Tube Driver. The pedal sports five knobs – Drive, Level, Treble, Middle and Bass. The second pedal was a prototype aimed at supplying Dumble-style tones. John was kind enough to give us a quick demo of the pair. While the T-Drive offered up a more biting, cutting tone, the D-style pedal created a more ‘expansive’ sound. Check out the pedal pics after the jump!
