Description
Introducing the Seymour Duncan Shapeshifter Stereo Tremolo, a guitar effects pedal for the discerning musician. This pedal is not just another tremolo effect; it's a musical tool that offers unprecedented tonal control. Whether you're looking for a subtle shimmer or a pulsating throb, the Shapeshifter can deliver.
The Shapeshifter boasts an all-analog signal path combined with the precision of digital timing. This means you don't have to compromise on your tone to get the tremolo effect you want. The true bypass feature ensures that your signal remains intact when the pedal is disengaged.
The Shapeshifter has been designed with versatility in mind. It features variable wave shape options, ranging from sine to triangle to square waves, and everything in between. With its rate/ratio switchability, you can adjust the speed of the effect to your liking, or sync it to the beat of your music using the tap tempo control.
Furthermore, the Shapeshifter is not just a mono pedal – it's stereo. The inbuilt phase control lets you adjust the phase between left and right output channels, creating a spatial, three-dimensional tremolo effect.
This pedal is more compact than its predecessor, making it a space-saving addition to your pedalboard. The Seymour Duncan Shapeshifter Stereo Tremolo is the perfect choice for any guitarist aiming to add that unique touch to their sound.

This is my favorite tremolo
The tap tempo and the light makes this tremolo really functional live. The tone from this effect is pretty stunning. The flexibility for this can change between time or ratio. The attack can be adjusted to the attack or fundamental.
