Model 33
Sinusoidal LFO pitch vibrato (slow warp to ultra-fast wobble) with phaser mode via dry blend—9V center-negative.
The Model 33 delivers authentic pitch vibrato using sinusoidal LFO modulation without delay circuits—pure pitch shifting achieved through analog means rather than the delay-line tricks most modern vibrato pedals employ. Speed range spans everything from slow warp similar to degraded VHS tapes or Leslie cabinet rotation, all the way to ultra-fast pulse wobble impossible with mechanical rotating speakers. The red jewel light pulses to visualize vibrato speed, providing tactile feedback during performance.
A switch mixes in dry signal to transform the vibrato into phaser tones, allowing the same circuit to serve dual purposes without requiring separate pedals. Slower speeds create hypnotic seasick pitch drift suitable for psychedelic textures, medium speeds evoke rotary speaker simulation, fast speeds produce tremolo-like rhythmic pulsing with pitch modulation adding movement beyond simple amplitude modulation. The analog LFO produces smooth, organic modulation rather than the stepped or digital artifacts of DSP-based vibrato circuits.
9VDC center-negative barrel plug power only. The Model 33 forms part of Templo Devices' Model series (including Model 66 stereo version), targeting players seeking authentic vintage vibrato character in compact format, suitable for psychedelic rock, shoegaze, and experimental music where pitch modulation creates movement and disorientation beyond standard tremolo or chorus effects.
