We are playing an amazing early 1970s Kustom K150-8 Tuck and Roll Amp. This amp produces so many classic instantly recognizable tones! And it's actually completely solid state!! It's a 4x10 combo using CTS Alnico speakers. Simon Karlsson is playing a 1969 Fender Stratocaster and I'm playing a Gibson Custom Shope 1974 Les Paul Custom Reissue.
