I'm with Richard above for plectrum guitar.
Variaxes sound great in the shop, where you can be impressed by how close the tones are to the original guitars modelled, however, the limitations of the modelling shows up more live. There is a little latency with some models. Also, you have to play it like the modelled guitar to get the effect i.e. play the Variax like you would a Strat on a Strat setting and like a Les Paul on the Les Paul setting. Not as easy as it sounds.
