High-dynamics stereo reverb effect unit with various reverb types. - Model Name: DynaVerb - Type: High Dynamics Stereo Reverb - Edition: Guitar edition - Manufacturer: EBS Sweden AB - Controls: REVERB, TONE, TYPE (HALL, PTE, ROOM) Thank you for viewing. It has only been used indoors, so I think it's in relatively good condition, but please purchase it if you understand that it is a used item. It was a very easy-to-use reverb, but I am selling it because I have less opportunity to use it due to the introduction of a multi-effects unit.
