hey everyone. this is my first post here. i have a quick, question. its probably going to sound like a stupid, noobie question, but i have to ask. im looking to buy this head: http://cgi.ebay.com/Hartke-LH500-50...tem&pt=LH_DefaultDomain_0&hash=item3a5a830e2b i'd like to buy a hartke cabinet too, but im not sure how to determine which size cabinet to buy. i dont really know anything about OHMs, and stuff like that. i've been playing for a few years, but mostly on combo amps. the last thing i would want to do is blow up, or damage the brand new head by plugging it into the wrong cabinet (can that happen? lol) like i said, this is probably a stupid question, but i figured this would be a good place to ask it. any response is greatly appreciated.
