The Electro Harmonix Bassballs is a twin dynamic envelope filter that'll work on both guitar and bass. The Bassballs uses two sweeping dynamic filters that respond sensitively to attack variations by creating shifting peaks and notches that produce vowel-like overtones. The switchable distortion mode intensifies the overtones. The "sensitivity" control determines how the filters respond to playing dynamics.
