Tech 21 TRI-O.D. Manual

PRODUCT OVERVIEW

INPUT

This triple channel switching overdrive stomp box offers true channel switching

between three completely different tube amp characters, "Tweed," "California," and

"British." For greater flexibility and usefulness, each channel is independent with its

own Drive and Level controls.Tech 21's custom footswitch actuator provides a

smooth transition between channels for instantaneous switching.

The TRI-O.D. can be used for live performances with an amp/combo, or to drive a

power amp and guitar speaker cabinets.Turning off all 3 channels enables you to

use the Speaker Simulator and Master Output Section only.This feature is useful

when you want to record direct with a pre-amp, fuzz box, or any other stomp

boxes in your collection.

Manufacturer of the highly-acclaimed SansAmp

line of Tube Amplifier Emulators,

Tech 21's proprietary circuitry is engineered in the true tradition of tube ampli-

fiers in their totality --with a pre-amp stage and an output stage. It incorporates

the harmonics and sweet overdrive characteristics uniquely inherent to tube

amplifiers.This is largely caused by what is referred to as "push-pull" symmetrical

clipping, which a single tube is physically incapable of accomplishing.

The TRI-O.D. employs aspects of this technology to deliver the same dynamics,

responsiveness, and sound quality of the top pro stage rigs in a conveniently

portable, switchable, pedal format.
