Hi all. I'm looking for a little advice. I currently have a Peavey Mark III XP head and am looking to upgrade to something a little more powerful for not a ton of money. I'm currently looking at a Peavey Firebass 700 for $255 or a Kustom KXB500 for $340. I've read threads specifically talking about the virtues of both of those heads, but keep wondering of the extra money is worth it for the difference in weight. (Peavey Firebass is 50lbs vs. 5 lbs for the Kustom.) I do like the tonal qualities of my current Peavey and it's been a real tank and extremely dependable... Anyway, if someone could help me add any color and to choosing between these two (or would recommend something else in that price range) it would be greatly appreciated.
