I bought this at the NAMM show when they first showed them...this was their demo unit and it sounded great, so I got Mike Matthews to sell it to me. I've used it sparingly in my home studio, but once I got the MIG 60, I used it for bass on occasion, sounds great for bass too. All original as purchased directly from New Sensor Corporation. Spare fuses in plastic bag still attached to handle. Sounds very much like an old Bassman or 50W Plexi (especially if you run both channels together). Runs off of three 12AX7 preamp tubes and two 6L6 power tubes .Dual voltage 117V/220V. Please no trades.
