Positive Grid Bias Modulation Twin

9 modulation effects types with infinite customization options

To begin creating your custom modulation effects, BIAS Modulation Twin offers nine distinct effect types: Chorus, Vibrato, Flanger, Rotary, Phaser, Tremolo, Pan, RingMod, and AutoSwell. The LFO section lets you choose from sine, saw, and square waveforms for creative flexibility. There's a Tap Tempo footswitch to control the LFO speed, and you can control any parameter in real time by connecting an expression pedal (not included).

Mix and match two simultaneous modulation effects
The modulation effects in BIAS Modulation Twin are arranged in two groups, and you can combine effects from both groups for even more sonic complexity. You can combine any of the time- and filter-based effects (Chorus, Vibrato, Flanger, Rotary, Phaser) with any of the amplitude-based effects (Tremolo, Pan, RingMod, AutoSwell).
