Me personally, i own the gmx212. It gets a better marshall sound than any of the low end marshall gear. It has mesa boogie
tones as well as marshall and fender tones, but ive never really used the boogie sounds. The clean sounds on the fender are pretty good as well (for such a cheap amp). Your friend definitely needs to try the gmx212 out. Probably the best value amplifier thats out there today.
