SUPRO S6420 THUNDERBOLT GUITAR AMPLIFIER
The S6420 Thunderbolt may only have 2 knobs, but don’t underestimate this very capable and versatile amplifier. Based on the original 1964 design, it outputs 35 watts of class A power from a pair 6L6 output tubes and features a 5U4 rectifier tube. A 15” speaker completes the setup providing a big bold sound with beautiful lows, great for everything from jazz to rock. All Supro models feature USA-made speakers designed in collaboration with Eminence that provide vintage tone with increased power handling capabilities.
