Sub-Octave and Envelope Controls for Dynamic Tones
The MXR Bass Synth is designed to help you dial up the funk and dig into your signature sound with a full suite of intuitive controls that deliver everything from thunderous low-end growls to elastic retro sweeps. The Sub Mix blends the sub-octave with the main synth signal, letting you dial in a fat, room-shaking foundation. The Envelope knob adjusts the filter response, offering everything from snappy, percussive textures to smooth, sweeping transitions. These controls allow players to create distinct and dynamic tones that are ideal for both rhythmic grooves and melodic lines. Together, they provide a versatile tonal palette tailored for bassists looking to add new dimensions to their sound.
Selectable Waveforms and Oscillators for Custom Sound Design
At the heart of this pedal's synth power are its waveform and oscillator options. The Shape button lets you toggle between triangle, sawtooth and square waves, each offering a unique tonal character—smooth and subtle, rich and aggressive or fat and punchy. Paired with the Voice button, which adds harmonically tuned oscillators, these features give you the ability to create layered, complex synth textures. The result is a full-spectrum synth sound with a playing response that feels tight and expressive. Whether you're conjuring vintage analog-inspired sounds or blasting off into futuristic funk tones, the Bass Synth is all about expanding your sonic possibilities.
