In an effort to avoid repeat of RSI, I need to reassess my setup and would be grateful for opinions on the following. I don't think I've heard myself properly when playing live - and I now play in a wind band so I'm sat down by my amp and that's just the way it is. The amp is on a chair in an effort to get it closer to ear level. I could get a bigger amp (in output not necessarily dimensions!) but I fear the problem will be the same, so I reck I need some form of monitor pointing directly at me. So I'm thinking: get a line splitter of some kind and run 2 amps off it, the main one and a smaller one (15-20W) at 90 degrees to it OR some headphones. I use the phrase "line splitter" but I've no idea if this is an official term... do such things exist? Are they cheap? Are there ohmage issues? Could I stick headphones straight in or would I need a second amp whatever? Blah blah blah blah.
