Mesa/Boogie 55 Stereo Amplifier User Manual


 
Nomad amplifiers are available in many configurations in terms of power / speaker combinations, as well as “head only” formats. All
Nomad amplifiers share basically the same pre-amp and since most Mesa/Boogies are available in many choices as to power and
speakers, for all practical purposes, Nomad refers to this pre-amp.
Pre-Amp:
The Nomad pre-amp is comprised of three discreet Channels which may be footswitched between. Each of these channels
offers two manually selectable Modes of operation. In basic terms, each of these modes offer a choice between a lower gain, slightly tamer
voice and a wilder, gainier personality. This is an extreme simplification of their individual character however, as they all move easily across
a wide range of sounds, prompting us not to limit them with the usual Rhythm and Lead nomenclature. Thus you will find them named and
referred to as Channels 1, 2 and 3.
The Modes have been named in each Channel for ease of comprehension and identification - especially for the first time pilot - with their
most common application labeled “Normal”. (Found with the mini-toggle in the “up” position.) When all three channels are “normalled” the
player is presented with one low-gain clean (Channel 1), one medium-gain, turbo vintage (Channel 2) and one high-gain modern channel
(Channel 3). In this way a great slice of the amplifiers many flavors can be sampled quickly and instantly from the Footcontroller.
For the more adventurous, the Channels may be switched out of their NORMAL Modes and three entirely new channels may be explored.
