Selling my Supro Thunderbolt MKII, one of the most iconic “happy accidents” in amp history. Originally designed as a bass amp, it quickly became legendary among guitarists for its massive, raw, overdriven tube tone. Players discovered that when you crank it up, it delivers some of the most glorious vintage distortion ever heard — the kind that inspired countless rock tones of the ’60s and beyond. Even Jimi Hendrix was spotted using one early in his career.
This MKII version keeps everything magical about the original while offering modern reliability and a switchable power section for more versatility. It’s the perfect grab-and-go tube combo for vintage rock, blues, or anyone who loves rich, harmonically complex breakup.
Features:

Cathode-biased 6L6 output section for classic vintage feel

Switchable power: 35 watts Class A or 65 watts Class A/B

1×15" Supro TB15 custom speaker – huge punch and warm mids

Simple Volume + Tone controls for fast, musical dialing

Excellent pedal platform

Thick, expressive natural overdrive that gets better the louder you push it

Looking to trade? I’m open to trade offers. Let me know what you have – I would be interested in other guitars, amps, or gear. I may also be open to high end woodworking hand tools (Lie Nielsen, Veritas, Bridge City, etc), high quality Swiss, Japanese, or German made watches, or potentially hunting items.
