This has been a great head for driving my Aggie GS412 but I'm selling that cab (see post in this forum) so I won't need this anymore. It has all the bells and whistles and 1200 watts bridged into 4 ohms is nothing to sneeze at. I like the fact that I can drive two 4-ohm cabinets with 600 watts each with it. If you like the sound of your bass and your cabinet(s) then this is the head for you - very clean and accurate.

It's in the Carvin rack and I have the original box for shipping. These are on sale from Carvin for $549. Mine is like new so I'll sell for $425 plus shipping. For trades I'd consider a Walkabout, M-Pulse 600, Whizzy, or a Bag End Coax 15, cash either way as appropriate.
