Pulling from the classic funk sounds of Stevie Wonder's "Higher Ground," the 3Leaf Audio Wonderlove is a juicy envelope filter that will take your sound to the extreme. Featuring controls for sensitivity, attack, decay, tone, blend, and even resonance, the Wonderlove gives you an immense amount of control over your filtering sound and a huge range for filter sweeping. Range, sweep, and band switches just serve the pedal further, and an expression pedal input gives you the power to create wah-like filter sweeps.
