Vacuum-Tube Waveshaper and Ring Modulator
The R-53 is directly derived from Metasonix’s legendary TM-1 device. It uses a 12AF6/BD6 remote-cutoff pentode and a 12AV7 dual triode.
Waveshaping is provided by a vacuum-tube “pulser” circuit that spits irregular pulses onto the input waveform. They synchronize erratically with the input pitch (if a waveform with sharp transitions is used). Combined with true vacuum-tube circuit distortion, this can provide a vast range of complex, aggressive distortion effects, utterly unique in the world.
A basic ring-modulation function is also available in the unit-applying a carrier pitch from an external oscillator to the screen grid of the pentode, this allows making inharmonic sum-and-difference pitch sound effects, with a unique vacuum tube pentode sound.
