Well, I don't know a heck of a lot about amps, but what I do know is my current amp is small and would like to upgrade to a small - medium gigging amp set up. However, I really don't know anything about amps at all so a little background knowledge would be very helpful, because I honestly do not know where to start.Like what's a head unit etc? How are all these things set up? To name a few. What do you guys think of an amp like the vox T-60? Thanks for any help.
