Derek Trucks’ Supro Thunderbolt S6420

Derek used a Supro Thunderbolt amp on the 2022 record I Am the Moon, although it’s unknown to which extent. In the Guitar Player interview quoted below, he calls the amp an old “lighting-bolt” Supro, but he was obviously referring to the Thunderbolt.

The Supro Thunderbolt S6420 is a small 35-watt combo tube power with a single 15″ Jensen speaker, introduced in 1964 as a bass amp, but was quickly adopted by guitar players. As far as famous users, Jimi Hendrix was seen using one, and it was believed for a long time that Jimmy Page used one on Led Zeppelin I record, but that turned out the be a Supro Coronado

The main tracking amp (on the I Am the Moon album) for me was a ’64 Fender Deluxe Reverb, which has an incredible sound. I also used a Vibrolux occasionally and a little tweed Deluxe that I used here and there, plus a real old lightning-bolt Supro.
