I have a AG500 Aguilar Head with two channels and two GS NT 1x12 with tweeter both of them in mint conditions. Thinking to trade them for your Mark Little Mark Tube 800 Bass Amp and your 4x10 and 1x15 cabinets or Two 4x10.
I will prefer to do a local deal but I can ship it too. Let me know mine is in mint conditions the cabinets have the padding covers and the amp is in an Aguilar Rack bag.
