Sansamp Tri - AC - 3 channel amp sim pedal featuring California (mesa boogie) Blonde (Fender) and British (marshall) voicing. I swapped the knobs for better aesthetics. I also replaced the LED bulbs from stock red to bright white. I always had trouble seeing the red light during gigs since they were so faded. Much better now. No original box, no power cable. I used a walrus canvas power supply and it was just fine. It has some signs of play being probably 12-15 years old, but it is built like a tank. Very sturdy pedal, switches and knobs function perfectly no static. Has 9v battery compartment that also works.
