For the money the amp can not be beat. I needed something to take to the rehearsal studio since a bass amp was not available. The GK MB series has had many QC issues. In all inexpensive combos they tend to sound a little "boxy" but this is not too bad. The fretless sounds great thru it. I corresponded with Ed Friedland before his review was posted in bass player mag. He liked it. Just said it was somewhat power deficient for larger gig work.
