A valuable vintage effects unit now, a reverb-only machine. This is a very simple analog effects unit with just knobs, and it can be rack-mounted. I confirmed it powered on and worked by connecting a guitar and getting reverb. It produces a powerful, thick sound quality reminiscent of the good old days (this is just my personal impression, for reference). It's a KORG digital reverb unit, which is still valuable for its variety of reverb patterns. The exterior doesn't have any major damage, but please be aware that there may be some minor scratches. Please refer to the photos. - Brand: KORG - Model: DRV-1000 - Type: Digital Reverb - Controls: Level, Mix, Pattern Select - Patterns: Small Hall, Medium Hall, Large Hall, Cover, Vocal Plate, Studio Reverb #EffectPedal #Reverb #ElectricGuitar #RackMount #Digital #Korg #KORG
