Sansamp Bass Driver DI preamp pedal. Traded another TB'er a Sadoswky outboard for this a while back and haven't been using it. Fantastic rich tube sound, though. This pedal is in perfect mechanical condition--works just like it should. Cosmetically, it has a little normal wear and one knob is not original. Also, I special ordered the AC adapter from Gard--a $15 value. $130 shipped to your lower 48 door.
