I just recently purchased a mesa 400+ and I'm using it with an 8 ohm SVTHEN 4 x 10 cab. Two of my friends run this amp with an ampeg 8 x 10 and i loved the way it sounded. I can't upgrade to the 8 x 10 because of transportation problem. I feel like the cab I have now isn't coming close to matching the sounds I got from the 8 x 10. Should I add another 8 ohm cab (4 x 10 or 1x15) or just wait a few months until I can get the 8 x 10? ANY suggestions would be greatly appreciated! Thanks!
