I'm selling my Darkglass M900. This amp was the very first batch sent over to the US. You can tell by the typo on the single footswitch that says "Darkglasss". Includes the original box and signed letter from Doug at Darkglass. I love everything about this amp, but its just too much for what I need, and I recently bought a Genzler head. With that being said, no trades please. Need cash to offset my Genzler purchase $800 shipped CONUS.
