The JT/PLX hybrid is a 30w KT66 output section driven by a modified (EVH) "plexi" preamp section. With output tube overdrive via Power scaling, by London Power at any volume, the Unique master volume can be used (or not) to achieve the maximum sustain and dynamics that pushed tube amps are famous for. Hyboer PT, Marstran OT and a Mercury Magnetics choke that meet vintage specs and an industry standard no loss effects loop bring a classic back that is as usable at the gig as it is at home. Standard two-year transferable warranty covers parts and labor (excluding tubes).
