From the seller

Even still today very underestimated effects unit which fits to all sort of music! Editing of the effects is easy and logical. You can do all sort of wild chaining and even add external effect to the loop or do sampling! Works as it should. Internal battery has been changed to new one and battery holder installed to make the future changes super easy. New display installed. Reset to factory presets. Scratches and other signs of usage etc here and there. Comes with original 230V power supply. What internet says: 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. Unlike its later siblings, the GT only has eight different effects routing combinations. While this may sound like a limitation, in fact you will be hard pressed to not find a combination that works for the effect you are trying to achieve. The default effects are great, but are primarily aimed at guitarists with lots of overdrive and distortion. It is a good thing that any of the presets can be overwritten for those who are using other instruments. Every effect has several editable parameters that allow you to fine tune the sound. Eight parameters can be controlled in real-time via midi.
