Jimi Hendrix’s Supro S6420 Thunderbolt

The Supro S6420 Thunderbolt amp is often claimed to have been used by Jimi Hendrix during his early days with Curtis Knight, around 1966. However, while some argue that an amp resembling a Supro Thunderbolt appears on stage behind Jimi in at least one photo, the credibility of this claim is highly questionable. The theory seems to have originated from someone’s statement, which led others to retrospectively search for evidence in photos of Jimi.

The primary issue with this theory lies in the physical details of the amp in question. The amp on the left edge of the photo below, which some claim is a Supro Thunderbolt and appears to be the one Jimi’s guitar was plugged into, has metal corner guards and controls on the front. By contrast, the Supro Thunderbolt is a much simpler-looking amp with no metal guards and controls located at the top. This makes it far more likely that the amp in the photo is a Fender combo rather than a Supro.

A Supro similar to this was given away in the nineties, by one of the major guitar mags. Said to be Jimi’s. Years later my friend said he acquired it, and later sold it to Pete Townshend.
