Up for sale is my Mesa M9 Carbine. This amp is not for the timid. With huge low end and a midrange and top end that sends most for cover, it can do pretty much anything. With the GEQ you can trim the lowest slider (33 hz) for the boomiest stages. The onboard compressor works extremely well too. This is a grindy, growly amp in position 4 or 5 and can do the dub step in positions 1 and 2. Between Mesa's prepositioned EQ and the GEQ the tone possibilities are endless. I have gigged this amp and used it in my rehearsal space. It has been sledgehammer reliable and is a post 500 serial number amp (517). It includes the vented top cover and has all the upgrades from Mesa. There is a slight bend to the left rear handle....nothing major and doesn't affect anything. I do not have the footswitch for this unit. It did not come with it. I'm asking an extremely fair $775 for this beast and that will include shipping to the lower 48. Paypal and no trades please. Let me know if you have any questions. Thanks!
