The Plex is Dave Friedman's reading of his own 1968 JMP Super Lead, the amp that set him off building. It is 50 watts from two EL34s and three 12AX7s, with a Lead channel and a Normal channel that each get a volume control and run without a master, the way the '68 did. Push them harder and they give back more saturation.
Friedman added two things the original never had. The channels are jumpered inside the chassis, so blending Lead and Normal is a turn of a knob instead of the outside patch players used on vintage Plexis. A post-phase master volume then brings a cranked amp down to a usable level. Each channel has a 3-way Bright switch, there are Hi and Low inputs, and Bass, Middle, Treble and a global Presence finish the tone stack.
It is the first amp in Friedman's Vintage Collection. The Smallbox Head shares the 50 watts and the pair of EL34s but puts a plexi-style channel beside Friedman's modern high-gain channel, each with its own gain and master. The Plex is the one to choose when the Plexi is the whole point.
