This is a hand-wired, custom amp made from a vintage Supro Calypso Blue cabinet and a Hammond AO-29 chassis. The circuit has an almost exact clone of a Marshall JCM800 in the preamp with an 18-Watt Marshall style EL-84 power section. The rectifier is a tube GZ34. The speakers are 2x10" Eminence Legends. Cab is finger jointed solid pine. It is believed to be an original Valco cab from the 60s. The baffle, grill cloth, and Supro logo were added later.
The tone is OUTSTANDING! If you like the tone of the JCM800 or late 70s JMP 2203 and 2204 series amps with the Master Volume, but don't need 50 or 100 watt beasts, this is your ticket! The 18-Watt style output is more than enough for most gig situations. The tone is clear and punchy with good headroom, yet gritty when pushed into overdrive. Not that it needs them really, but if you are the type who likes to get your dirt with pedals, it takes pedals very well. Any tube screamer type pedal will send this into lead heaven.
To my knowledge, there isn't an amp like this on the market. Marshall's EL84 amps made currently are all made with wave soldered PCB boards and aren't anything like this in terms of the circuit or the tone. This thing will eat the little DSL401 combos for breakfast. Like Mike Tyson, it feasts on the children of DSL401s.
