THE LONG STORY

The MXR Bass Envelope Filter delivers classic analog envelope filter sounds in an easy-to-use and compact pedal designed specifically for bass. Separate Dry and Effect controls let you dial in the perfect mix of effected and direct signals, so you can bring the funk without losing the low end. Its wide range of filter tones can be shaped with the Decay and Q controls, and a simple twist of the Sensitivity knob can tailor the pedal for your attack—as well as adjust for passive or active basses. The Bass Envelope Filter’s power supply circuitry is designed to withstand over-voltage or polarity mishaps, and its true-bypass switching preserves your tone in bypass mode. It’s all packaged in a durable, lightweight, Phase 90-size aluminum housing for the ultimate in portability and pedalboard space-saving dimensions.

CONTROLS

1. DRY knob controls volume of unaffected signal
2. FX knob controls volume of envelope filter signal
3. DECAY knob sets envelope filter’s decay stop frequency
4. Q knob controls intensity of effect
5. SENS. knob adjusts the sensitivity of envelope filter to your attack
6. FOOTSWITCH toggles effect on/bypass (blue LED indicates on

DIRECTIONS

• Run a cable from your bass to the Bass Envelope Filter’s INPUT jack and run another cable from the Bass Envelope Filter’s OUTPUT jack to your amplifier.
