"One used Metasonix TX-1 SE, that's for special edition. With Power Supply and manual (which tells you all about it and yourself!) This is unit 43 of a limited run of only 100 ever made. If you are looking at this you know what it does, but until you own it, you haven't experienced it. It's the shizzle for distortion. You've also been warned that this unit will blow out your speakers if you aren't careful, no kidding! Very low hours on the tubes, hardly used.

The TX-1 is an analog synth module that incorporates a pair of obscure tubes to create a waveshaper supreme. According to the manual, the harshness of the TX-1 is due to the nonlinear quality of the tubes , and the misuse of the tube's beam modulator in particular.

The Strangle knob does what the name implies: at the highest setting, it chokes off the sound — particularly the hum and original tone as if it is fully shortening the duty cycle of a square wave.

The Grind knob controls a feedback loop that creates instability in the beam modulator.

The CV input can be used to control the Pound circuit, which adds further complexity to the distortion. A typical CV with a 10V range can be sent to this jack, and the most interesting results using the signal from an envelope generator

TX-1 can obliterate any sound going though it. The resulting distortion isn't the light, sweet kind you get from a typical fuzz box. Rather, it's thick and intense and threatens to explode.

The TX-1 can be used in a guitar effects chain but works best with line-level source material that is harmonically rich to begin with (electronic percussion and nasty synth tones being the best). By design, its overall behavior is unpredictable. For example, the controls don't change the sound in a linear way: as you turn a knob, the sound may begin to break up nicely, then clear up a bit, then break up in a different way. But if you think having Level, Pound, Strangle, and Grind at their maximum settings will give you the noisiest, most intense sound, guess again.

TX-1 Special Edition has a switchable highpass filter in the circuit, referred to as Suckbass.

There's nothing polite about the sound of the TX-1. If you think you've heard it all, guess again. For truly rough and messed up sounds, the TX-1 SE Agonizer moves to the front of the line..."
