Description

The Dr Wub is a stereo harmonic tremolo designed to transform simple amplitude modulation into a swirling, panoramic tone engine. This pedal features independent per-channel tremolo modes, eight selectable waveforms (plus a hidden second bank), expanded harmonic depth, and tap tempo — all through a fully analog signal path running at 20 volts for increased headroom. This version of the Dr Wub features dual input and output jacks for alternative routing options and true bypass vs the buffered bypass of the dual TRS Jack Dr Wub.

Drive Control (+17 dB Clean Boost):
Push your amp, lift your signal, or compensate for depth-heavy modulation. Up to +17 dB of boost. Can be used as a preamp at minimum depth settings to push proceeding devices into overdrive. Great for compensating for perceived volume loss.

Dual-Mode Tremolo Per Channel:
Each side of Dr Wub can independently run in standard tremolo (amplitude modulation) or harmonic tremolo (split high/low modulation). Left and right operate separately — mix and match modes for layered movement. Pan between channels with both trems set to standard mode. Dial in classic bias-like throbs, smooth optical pulses, or swirling harmonic warmth.

8 Main LFO Waveforms:
Choose from eight shapes to sculpt your modulation: Sawtooth, Reverse Sawtooth, Square, Triangle, Sine, Sweep, Lumps, Random.

Alt Bank LFO Patterns: Ramp +Oct, Quad Ramp, Quad Pulse, Tri Step, Sine +Oct, Sine +3rd, Sine +4th, Random Slopes.

Enhanced Harmonic Depth:
Dr Wub’s harmonic tremolo mode goes deeper than vintage circuits. The increased depth of its high and low pass filters impart an almost phaser-like aspect to the sound. Warm vintage wobble or intensely submerged psychedelic warping.

Stereo Harmonic Split Output:
When both Tremolo channels are set to Harmonic mode and you select Split output: Trem 1 (Left Channel) = high-pass tremol; Trem 2 (Right Channel) = low-pass tremolo

This creates a unique stereo image where frequencies dance across the soundfield — a rotating sensation that feels alive and immersive, like standing between two mismatched vintage amps being alternately modulated.

Optional Right-Channel Phase Flip:
Flip the audio phase of the right channel to create additional phase interaction between the two sides. Enhances stereo width and spatial movement, Produces deeply hypnotic patterns when paired with the complex LFO shapes, Increases the three dimensional sense of modulation, especially in harmonic mode. This simple switch dramatically expands the dimensionality and psychoacoustic behavior of the effect.
