I purchased this Genzler acoustic amplifier 2 months ago to use with my upright bass, but it sounds great for acoustic guitar as well as many other acoustic instruments. (It also works well for electric basses according to the guys at Gollihur Music.) I also purchased the protective cover, which I'll include with the sale. This is the exclusive Gollihur series of this amplifier and is the result of a special collaboration between Genzler and the guys at Gollihur Music. I've barely used it in the short time I've had it, and it's in excellent condition.
