I have had a 4010 (1x12 combo version of the 50 watt 2204 model) for 11 years. About five years ago I built a head to mount the chassis in, and have been running it through a 2x12 cab. It's a one trick pony, and does that trick really well with the right guitar (something with loud humbuckers) at a good volume. Unfortunately since buying an Eganter TOL50 about seven years ago, the 800 has been my bedroom/backup amp and the tones I get at bedroom volumes with single coil guitars are less than stellar. I do believe with the recent purchase of a RM50, the 800 is going to get sold.
