Item may be on display!
(Incl. Taxes & Shipping Cost)
Designed with low-end professor and tone connoisseur Ian Martin Allison, the MXR Bass Synth is a powerhouse of a pedal offers thunderous sub-octave, expressive envelope, and lush modulation effects with killer tracking and sustain—plus all the features you need to shape every detail of your tone.
This pedal requires a 9-volt (330 mA) center-negative power supply and can be powered by the Dunlop ECB003 9-volt adapter or the MXR Iso-Brick, the Iso-Brick Pro, and the Iso-Brick Mini Power Supplies. This pedal cannot be powered by a battery.
Features:
- VOICE button adds additional oscillators harmonically tuned for more complex tones
- CUTOFF knob sets the 4-pole resonant low-pass filter’s cutoff frequency
- SUB MIX knob sets mix between the main synth and sub signals
- SHAPE button selects oscillator waveform (Triangle, Sawtooth, Square)
- ENVELOPE knob controls the attack/decay
- PRESETS button selects one of 8 different presets
- Input Impedance: 1MΩ
- Output Impedance: 100 Ω
- Maximum Input Level: +5 dBV
- Noise Floor: -97 dBV
- Current Draw: 330 mA
