Sorry - I should have said 'harder' to play. It's all relative.

I have tried out several of them over the years and have never found them comfortable to play sitting though admittedly I've never tried classical style (do you use a footstool? Not very 'rock'

). BTW - I'd say that the body is bigger than by a business card's width judging by the collection pic:
...looks about 'a pickup and a half'.
I've been toying with the idea of getting one for many years and almost got one of the VOS Jimmy Page ones, but didn't in the end mainly due to lack of space to put the thing.
