The Mooer ShimVerb is a great addition to any pedal board. It offers three reverb modes: Room, Spring and Shimmer. The Room reverb provides different sized, true acoustics reverb from room to hall. The Spring reverb simulates a classic spring reverb from the '60s surf rock era. The Shimmer reverb is a rich overtone reverb that's smooth, spacey and shining that's great for Alt rock, post-rock and anything with a more modern sound. Its full metal casing makes it durable and road ready, and like most great effects pedals it has true bypass.
