Peavey MK III Bass amp head and 2 Peavey 2x10-1x18 bass cabinets. This amp is rated at 300 watts @ 2 ohms which is where it winds up when you play through both of these killer cabs!Both cabs are 400 watts @ 4 ohms. Both channels work as they should or you can use the "Auto-Mix" input and play through both channels at the same time. This set up has a tremendous sound and lots of volume with both cabs going. This amp has a cross-over in the 2nd channel that allows you to adjust the lows through those big 18"s to suit your venue. One cab has casters, one doesn't to allow you to stack them if you want. One of the 18" speakers has been replaced. Cosmetics on all three pieces is pretty fair with a few small nicks in the Tolex here and there. Prefer a local exchange( VA, D.C. , MD.) area, but will work with anyone who is interested in this rig as much as I can. Additional photos available upon request. Any trade offer welcome--all I can do is politely decline the offer. Trades would be any Fender 4 strings of equal value.
