1966 Harmony 420 Amp Demo

Wonderful old amp here, basically the same as the famous Supro Thunderbolt!

I have this amp chasis in a two 10’ cab I play harmonica and it sounds wonderful!! I also play harp through an all original Thunderbolt- 15’ if you play harp you need to try these amps
But get the real ones not the re-issues if you can- cheers
