I bought an amp today, which hopefully will be my amp for many moons to come. It's a Hartke HA5000. Thanks to everyone here who helped me with all my amp questions. I came to the conclusion that I may as well invest in a decent and powerful amp now so I don't have to upgrade in the near future. I plan to match it with a pair of cabinets eventually, so I can run it at the full 500 watts. If I ever end up with a guitarist that overpowers me with my 500 watts I'll either quit the band or smash his amp! A few questions: 1) The amp runs biamped at 170 watts per side @ 8 ohms. Does that mean when in mono mode it will be running at 340 watts @ 8 ohm? The guy at the music store seemed to think so, but I could see the little question marks floating over his head so I wonder. 2) The amp came in some kind of metal shell. It is not rack mountable in it's present condition due to this metal case it's in. I planned to mount it in a new rack bag I bought. It looks like I can just get out the old screwdriver and remove this metal case, except for the big bolt on the bottom. (?) Is this easy enough? It's a nice metal case. It seems very protective and has little rubber feet, but I'd rather it in the rack bag. I assumed all Hartke heads are rackmountable. Do I just need to remove this metal case, or do I have a different version of this amp than the rack mount one? Thats' all for now. Soon I'll have a slew of question on what cabinets to get.
