Overview:
The Ethos Overdrive was inspired by one of the most
sought after boutique guitar amplifiers ever made.
Extensive time and attention to detail were required to
emulate the tone and responsiveness of this amplifier.
The key to Ethos tone, is its ability to transition from
clean to overdriven tones just by the articulation of the
guitar pick or guitar volume control. The Ethos not
only offers great tone and touch sensitivity, but also
provides a high degree of flexibility in one compact
package. The Ethos provides two independent
channels with an integral boost function resulting in 3
different footswitch selectable sounds. The Ethos can
operate in many working situations as well. It can be
used as a guitar amp pedal, a DI interface for broad
band systems (e.g. PA, studio, or PC ) and a preamp
that can feed a power amp/speaker combination .
