I recently got a hartke lh500 and an ampeg 4x10. Also I'm off work for a month. All I do is practice. All day everyday. I have another rig I can use but this one's new( to me) and loud and it sounds amazing. What I want to know is, if I'm playing at low to medium volume for 3-4 hours at a time through several stretches a day. Am I gonna blow my rig up? Or my ears for that matter, that's less of a concern though, I really don't play that loud. Except the first day Should I switch amps throughout the day? Or am I being overly concerned about nothing?
