Classic analog filter pedals for bass may be harder to come by than their guitar-oriented counterparts - but the MXR Bass Envelope Filter is here to fill that gap. Dry and Effect controls help you dial in your desired mix of affected and unaffected signals, and you can shape those filters using the Decay and Q controls. Sleek and intuitive in the small classic MXR housing, the MXR Bass Envelope Filter will help you add the subtlest of filters or totally bring the funk.
