There were two significant changes for 2003 - the introduction of the SX300H head/SX300 combo, and the SX300R preamp.  The Vai Legacy amps, MTS Tube Series amps, Vintage Tube combos and other SX amps were unchanged.  Unlike the bass amps for 2003, the catalog photography and layouts were basically the same as 2002.

The pictures and prices are from the Summer 2003 catalog.
