The Electro-Harmonix Wiggler is a tube-driven vibrato/tremolo pedal that houses a ton of vintage sounds in one box. This versatile pedal can switch between four different modulation modes that call up on tube amp tremolo, rotating speaker sounds, and even the luscious tremolo from old Wurlitzer electric pianos. The Wiggler's warm, rich tonality and convincing spin on the sound will have everyone in the room looking for the Leslie.
