A friend let me borrow his GK MBS III combo. I've never played through a GK amp before and I really dug the punchy tone it had. I play a Lakland Skyline 55-02 with Bart PU's. Right now I have an Ampeg PF500 & a GB Shuttle 9.2 that I run into two GB Neox 112T cabs. I tried to duplicate the same tone on the Ampeg and Shuttle but I couldn't really capture it. I was wondering which GK amp head might sound the closest to the MBS III? Thanks .
