Used Electro-Harmonix Bassballs Twin Dynamic Envelope Filter Pedal With Box

We have a classic envelope filter, this Electro-Harmonix Bassballs! This is the original model in the classic aluminum housing. Not one, but two narrow filters sweep your tones under control of the envelope, generating very unique vocal-like sounds. A distortion switch enriches the harmonics. The response control varies the sweep range determined by your attack. Not only designed for and great on bass guitar, but also very funky on guitar. This pedal is in good condition and comes with its original wooden box.
