A rich delay with optional modulation taken from Keeley's renown Magnetic Echo pedal, and three distinct reverbs plus tremolo and shimmer effects all in one sublime, easy to use, always great sounding pedal. Shimmer, Spring (with subtle, amp-like tremolo), and Modulated reverb sounds are available with the flip of a switch, and the delay effect can be toggled between no modulation, light modulation or heavy modulation.
