I have an excellent shape Carbine M9 I am offering up for sale due to too much gear and if not getting used frequently, it goes up on the block. This has the first 2 mods but still 900w (I think 840w or something from the mods). This amp has never shut down on me. There is zero issues and I play loud. You must rack mount these heads in 3 or more space racks so they can properly breath. A 2 space is not enough air circulation. These amps are only 29LBs and TONS of headroom. This is not a micro amp and sounds like a BIG amp as it should. Included in sale: +Mesa Carbine M9 Amp +Mesa Unused Footswitch, carry bag and cable. _I have a user manual in .pdf but if I can find the manual i'll include it. ** new pics coming in the next 24 hours or so when I get home. I prefer a local sale and will travel a little to meet up but might ship. I would need to get the box out of storage and negotiate a fairly shipping quote.
