CGS Metasonix TS-21 Hellfire Modulator

Hellfire Modulator The Metasonix TS-21 Hellfire Modulator is another of Eric Barbour's tube designs. It is essentially a custom built TS-21 Hellfire Modulator. These are available pre-built, in a 2U rack-mounting cabinet from Metasonix. Fairly obviously, this one has had one of my panel designs inflicted on it.

It could be considered as two effects in one, a pulse width modulator and a beam modulator. It is possible to get a wide variety of effects from this, from simple tremolo, to fairly serious wave mangling. The PWM section can be used to get some pretty aggressive sounds, which can then be modified further by the beam modulator (wave folding, tremolo etc.). A rather versatile module.
