Does anyone know the weight of the M-Pulse 360 and 600 ? Mesa-Boogie does not list much in the way of specs. Also what is the wattage at 8 ohms on the 360 and 600 ? I'm trying to find a light- weight powerful amp. I'm thinking about buying one tomorrow. Guitar Center has a finance deal where there is no payments/interest until 2004. I just have to make sure to pay it off before 2004 or they add all the interest from the date you bought it.
