SEYMOUR DUNCAN SHAPE SHIFTER STEREO TREMOLO PEDAL

'11900-005 Shape Shifter is a stereo tremolo designed to offer the classic textures you love with the ability to perform extreme effects such as helicopter cuts, piano stabs or backward bulges. It's the most versatile tremolo pedal you'll find, whether your style is a classic material atmosphere or an unexpectedly experimental one. The Shape knob allows you to control how the signal rises and falls, set it in the center for a traditional and smooth rise and fall effect, or rotate it left or right for wild effects that can simulate an analog synth attack.
