MTX8 Guitar is the same as the standard MTX8, except Input 1 features an input stage based on a Tube Screamer-type distortion pedal. It can be used to add gain and distortion to a guitar or microphone signal. It features a very high gain amplifier with clipping circuitry. The clipping circuit can be switched in and out as desired. The clipping characteristic is asymmetric, emulating the clipping behaviour of thermionic valves.
This input also features a high impedance JFET front end, an aggressive tone control, and has a first order high-pass characteristic with a -3dB point of around 200Hz which prevents low-frequencies from affecting the clipping behaviour adversely. A guitar could be connected to any of the MTX8’s inputs if a flat, parity gain, clean signal is desired.
