Supro Thunderbolt S6420 Combo Amplifier

The following description was carefully written by a skilled technician. Please contact us for more details if needed! Each amp is sold in as-is vintage condition as pieces of this age often need maintenance work for their aging components.

Thunderbolt is an appropriate name for this Supro amp. It has solid cleans at low volumes but this amplifier has a confident fuzzy growl when cranked. The amp has been serviced and has a 3 prong cable.
