The Nomad 55 is the 55-watt, three-channel member of Mesa/Boogie's Nomad series. Channel 1 is a clean channel with its own gain, tone stack, presence, reverb and master; channels 2 and 3 share a cascaded high-gain preamp with JFET-switched stages but have separate gain, EQ, presence, reverb and master. An op-amp-driven spring reverb, an effects loop with mix control, a solo level and a record output feed two 6L6s, bias-switchable for EL34s.
