I play classic rock, alternative, blues, and funk, and was wondering which one would fit me best. I also noticed the two channel one usually goes for less on ebay. Thanks
some people don't like how the two channels sound, but they both sound really good. if you need cleans in the amp, the two channel's the way to go.
The 2 channel version tends to be a little less crisp. That said, a good set of tubes and speakers will bring it up close to the level of the single channel version.
Some people don't like the diode clipping in the 2 channel JCM800s that weren't in the earlier single channel JCM800s. It lends to a fizzier tone.
