I'd suggest getting the head version instead, then when you've got a proper 4-12 like a Mesa 4-12, you'll see what the Mark IV is really about! 1-12's are cool for many applications, but nothing will give you the metal 'thump' like a halfstack. You might find the head cheaper on Ebay, too. I've run my amp through a 1-12, 2-12, and 4-12
and the sound just gets better with each step up. Plus, open back combo's don't retain the tightness on heavy palm mutes. If you go back to the music store, run a speaker cable from the combo's 16 ohm outlet, into a 4-12, and you'll see for yourself.
