I just got back my Gallien-Krueger MB2-500, which was upgraded to the A05 series. They shipped me a brand new A05 version. It works perfectly. I will be shipped the amp in the original GK packaging and includes all cables, footswitch and manual. Looking for $500 shipped to the continental US. This head is brand new, so... Save $100 off the MF price of a new head and just buy mine Only trades I'll consider are either Eden WT405 or WT550 with adjustments for the price differences.
