I bought this on an impulse and already have more pedals than I need. The pedal has never been gigged, only played once at home and has been in it original packaging ever since. I bought the bundle pack with 4 cables included for $135 + shipping, i'll sell the same bundle pack for $120 shipped.Here's a demo:YouTube - ‪MXR Bass Envelope Filter Demo‬‏ "The Dunlop M82 Bass Envelope Filter Pedal rocks the sound! It 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. The Dunlop M82's 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. Dunlop's M82 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. The Dunlop M82 is all packaged in a durable, lightweight, Phase 90 size aluminum housing for the ultimate in portability and pedalboard space saving dimensions."
