I tried out the LSS and also the Roadster for a couple hours at my local guitar shops...both are excellent, but obviously very very different amps.
In the end I went for the Roadster. So many options for routing FX, rectifier selection, power selection (50/100W), channel selectable effect loop and reverb level (and a very very nice reverb I might add), four channels, bold/spongy variac switch, and of course the nice liquid overdriven tone that I love so much. Although I really liked the crunchy tones of the LSS, it only got somewhat close to the level of drive I need for a good majority of my tunes. I would have to put an OD pedal in front and I (a) don't want to add anything else to my signal chain and (b) take chances with trying to find an OD that will give me what the Roadster can give me by itself anyway.
I jammed with my band on Friday night and I was really happy with the tones and having 4 channels was also REALLY cool. It passed the acid test.
