Spring Reverb models the sound and character of popular spring reverbs found in guitar amplifiers, popularized by Surf, Garage and Rockabilly music. Spring takes this a step further by allowing manipulation of physical parameters not normally available in a real spring tank. The results vary from faithful recreations of real springs to distinctive new sounds that push the physical boundaries of reverb. Guitarists love the revered surfer vibe but all creative musicians will find that Spring makes any synthesizer, drum, or vocal stand out in a mix. This vintage reverb sound originally derived from the reflections of sound waves traveling through springs has been given an overhaul for the 21st century and beyond. Eventide Spring contains two different sized ‘spring tanks’ along with the ability to morph between one and three springs. Easily program The Ribbon to seamlessly transition between any two settings in real-time! The added tube-amp-style tremolo can be routed before or after the spring resulting in an unrivaled ability to craft your own unique reverb sound. Alter the intensity by changing the tremolo depth and adjust the tremolo rate in Hz, or note value when tempo-synced to your project.
