Dual Envelope FollowerThe Electro Harmonix Nano Bassballs Dual Envelope-follower is the small successor of the legendary Bassball. Like this one, 2 'sweeping filters' create unique fat sounds. The intensity can be controlled by the touch; the more the response knob is turned up, the more the effect goes up... so sounds from soft and unobtrusive to 'completely over-wound' are possible. With the additionally activated fuzz effect the overtones are ignited even more... maybe the craziest AutoWah effect of all time!
