The Vermona VSR-3 is a vintage spring reverb effects processor with a simple control layout and authentic spring sound. VSR-3 uses a spring tank made by specialist AccuBell (aka accutronics), the spring chambers are of the highest quality and provide an accurate, authentic vintage tone. The control layout of VSR3 is simple; a gain control, tone pot, wet to dry mix control, output level and an effect stop button. The effect stop creates a "crashing" sound which is much sought after in vintage reverbs. This crash effect can also be controlled externally via a foot switch.
