The EC Twinolux is a 2011 Fender Eric Clapton signature 2×12 combo in the spirit of the late-1950s tweed Twin and Tremolux. Two inputs feed a paralleled 12AX7 stage, then a single Volume, Treble, Bass and Presence, and a 12AX7 tremolo oscillator with Speed and Intensity. A 12AX7 long-tail phase inverter drives two 6L6GCs on a pair of 5U4 rectifier valves, rated 30 watts RMS, with an output switch for full or reduced power.
