The legendary beast of a bass amp. I've had it for a decade and can trace its lineage back to the early 2000's. I've used it lovingly and kept it serviced and in 100% working order. Both channels work. All the faceplate silk-screen is worn away, which I adore, but this amp needs to go to someone who knows what all the knobs and switches do. Road case included in the price, but I could knock off $100 if you don't need the case. Dates to 1973-75, based on three-pronged plug, and interior fan.
