Re: How much does a Mark IV go for???
a new one is $1699 and i think that is for both long and short chassis. That's about the best your gonna get on price. Mesa doesn't allow dealers to give deals on their products, so they must sell at list price. If they catch dealers giving deals, i think they give a warning, then pull the line from the store. Except Guitar Center, they seem to get away with it. You also won't find them online because Mesa doesn't want stores shipping out of their designated market area. I've heard there must be 50 miles minimum between each mesa dealer. pretty harsh if you ask me.
Used, I've seen them go on auction anywhere from $800 to almost full price, depending on condition. Great amp though. I bought one and haven't had a single negative feeling about it. i'd get one used if you can find a nice one
