This beast of an amp is in great overall condition and includes the hard to find foot switch with bag and cable. All knobs and switches work, however, the input select switch doesn’t latch fully when pushed up to the A channel. It selects the channel properly and stays in position, but doesn’t seat like pushed down to the channel B selection. Per Mesa customer service, this amp has not been in to them for the “reliability update”. However, it already came from the factory with the vented housing, second cooling fan installed, and most up to date transformer, all of which were issues with earlier versions.
