Why no Markbass-ish guitar heads?

[BassmanPaul]

After a night of hauling my guitar player's gear all over the place, I couldn't help but wonder why you don't see more lightweight guitar heads and cabs out there. I mean, I know a clean tone doesn't go nearly as far with a guitar as it does with bass, but I would think that with all the pedal options that are available, you could get just as much tone (or a reasonable facsimile thereof) as you could with a traditional half-stack at half the weight.

Then again, Markbass is supposed to be spinning off a line of guitar gear soon...

I think it's fair comment that the vast majority of guitar players prefer full tube amps. MarkBass, I'm guessing, took its name from Marko building Bass amps.
