The Grape Phaser is a straightforward 4-stage analog pedal equipped with just two controls: rate and color. This reliable stompbox boasts a robust bypass switch and durable rubber knobs. The rate knob adjusts the modulation speed, ranging from a deep, mellow sweep to rapid-fire alien helicopter effects. The color control sends a portion of the signal back through the phase-shifting circuit. Powered by a 9V DC from your preferred universal power supply, it also accommodates a battery, which can be easily accessed through a smart metal drawer released by a single Phillips screw. Additionally, the pedal features Aguilar's "gig-saver" bypass, allowing the signal to continue passing through even if the power is cut. This functionality certainly lives up to its name! Plus, the pedal comes in a striking grape color.
