I have the opportunity to buy a Peavey 5150 combo in great condition for a very reasonable price. I have read the reviews on these but have never played one (it's out of state and is being sold by a friend of a friend who would bring back when in the area next week). I'm a rock/metal player and have a few Mesa Boogies and Crates (Stealth) that do the hi gain tone perfectly. Lately I've been doing a lot of Classic "arena" rock from the 70's and early 80's. My question............is the 5150 a one trick pony or can it do the classic rock sound? I know the amp does the hi gain sound very well but I've got that covered with current gear. Does it still sound good at lower volumes, etc? I have to hand over the cash this weekend if I want to pull the trigger on the deal, so I'm looking for some insight.
