Quick Overview:

True Bypass Modulation Pedal


Like its ground-breaking predecessor BIAS Distortion Pro and BIAS Delay Pro, BIAS Modulation Pro lets you easily design thousands of custom modulation pedals and expand your BIAS Pedal arsenal for a seamlessly integrated ecosystem of distortion, delay and modulation effects. Wrapped in the same expandable BIAS Pedal shell, BIAS Modulation Pro is available both as a cross-platform plug-in and iPad app, which travels effortlessly between stage and studio. And of course, it’s ToneCloud-ready. Upload and share your unique modulation pedals on the ToneCloud and download thousands of modulation presets from fellow musicians around the world. BIAS Modulation Pro covers every ground – and beyond.


BIAS Modulation Pro allows you to mix and match from two groups of modulation effects which includes time and filter-based effects (Chorus, Vibrato, Flanger, Rotary, Phaser) and amplitude modulations (Tremolo, Pan, RingMod and Autoswell). In the studio, sync BIAS Modulation Pro to your DAW’s global BPM for modulation rate ranging from a 32nd-note to a whole note, including dotted notes and triplets.


Craft your own soundscape from a comprehensive collection of modulation effects, from subtle, analog-sounding vintage chorus to over-the-top tornado and anything in-between. Experiment with different LFO waveforms and two 8-band graphic equalizers always at your fingertips. BIAS Modulation Pro gives you infinite tonal possibilities in a fast, intuitive interface.


BIAS Modulation Pro seamlessly integrates with your BIAS FX mobile and desktop effects arsenals. It automatically imports your custom modulation pedals into the BIAS FX pedalboards’ dual signal chains with dual BIAS amps. It also includes all of BIAS Pedal’s stock goodies, including Amp Room: six guitar amps from the rockin’ BIAS Amp to jam through.
