Alesis Quadraverb Plus

This is a fairly noisy, rough-sounding effects unit. The reverbs in particular can be quite grainy and metallic-sounding. However, it definitely has character.

I've never had any problems.

The main point I would like to make about the Quadraverb+ is that while I have found it to be a reliable workhorse, and do not regret buying it (I caught the last of the production models), DO NOT pay the second-hand prices that are being asked for these units! This is an OLD design, and while it may be a classic, it is simply not worth more than #100 when compared with modern effects units.
