Alesis QuadraVerb GT – Rack Mount Reverb Processor w/ Power Supply – Used

The Alesis Quadraverb GT is basically a Quadraverb+ with an analog preamp section tacked on for guitar effects. This unit allows you to have 11 simultaneous effects (6 analog + 5 digital). Its preamp section is geared towards guitarists, but it is great for adding the extra “grit” to keyboards or drums.
