Fitting six powerful modulation engines ranging from tremolo and vibrato to filter and phaser all commanded by a 32-bit microcontroller, the Alexander Pedals Wavelength High Bandwidth Digital Modulator shrinks a universe of modulation into a single stompbox. The MIDI-capable microcontroller allows easy recall of up to four presets, and expression control to do everything from control the "ramp" of an effect to morphing the chosen waveform in realtime.
