Metasonix Butt Probe TX-2

The Metasonix TX-2 is entirely made of vacuum tubes. To be specific, three type 4BN6 beam modulator devices. They were intended for use in crummy TV sets as FM detectors, and were NOT meant for audio applications. Only Metasonix knows how to apply these strange devices to audio processing. Instability is inherent in a circuit having this much gain, and the third tube provides an extra way of modulating the distortion. Basically, it is wired as a very bad bandpass filter. Filter center frequency is controlled with a "Vactrol" optical resistor, and swept continuously with an LFO built into the TX-2. The sweep may be disabled by turning down the SCREW knob or by plugging an unassigned 1/4" plug into the CV IN jack. If the latter is done, the SCREW knob will tune the filter manually, giving a vast range of NAUSEATING tonal effects not obtainable with any of the existing effect pedals on the market.

Manufacturer’s Suggested Retail Price: $549.00
