Modulation madness! The Electro-Harmonix Worm is an all-analog multi-effects processor featuring Phaser, Tremolo, Vibrato, and the never-before-heard Modulated Wah. At the heart of The Worm is a specially designed tone-bending engine which creates groundbreaking oscillatory effects.

Features:

• True bypass
• Mode selectable analog modulation effects: wah, phaser, vibrato, tremolo
• Manual mode removes the modulation so the effects can be swept by hand
• Optional expression pedal sweep capability
• Tough and compact die-cast chassis
