This fits the Performer amp really well, and as you probably know, Fishman amps have the worst Tolex covering on any amp ever made, and at the slightest touch it will rip or tear. So a good cover is an absolute necessity. This one is way better that the reappropriated 'stairville' bag the big 'T' is selling for this amp. If you have this amp, don't leave home without this case.btw, Muziker send this out really fast, I was expecting it to take a few weeks, but it arrived within a few days. So, I'm very happy with their service.
