I'm thinking of adding a 2x10 Hartke HyDrive or 1x15 Hartke HyDrive to my existing rig. (See pic) I'm perfectly happy with the sound that I get from just the 4x10 I just need to be able to hear it better. I suffer from hearing loss due to a career around navy aircraft plus I don't seem to have ears in my rear end. I had started a similar thread regarding just adding the 2x10 and thought I'd made up my mind. Then I thought about adding a 1x15 instead. I play in a weekend warrior country band. I'm looking for clarity and punch. I don't use any pedals at all and would like to keep it that way so as to keep my designated stage spot as compact as possible.
