Ryszard,

Mac's advice is well taken if you've had the real thing. I never did. Doesn't stop my from listening for differences in those amps in live and recorded settings.

I probably can't get all of the nuance out of an amp simulator as someone who has owned the real deal.

The V-Guitar is probably too complicated to start out with. My boss at my new job has one. Ridiculous the amount of settings one can change in that thing. I was at his place one evening and we never really got around to playing music, but fiddled with all the cool settings. Cool if that is the goal.

I would recommend instead simply getting one of the 'cover DVD' simulators - I got a cut-down version of of both Amplitube and Guitar Rig.

Plenty of power in there for me to try out the various amps. At least with Santana, if you use a 'California/Mesa Boogie' style amp with humbucking pickups, you can get a long way to the tone, rather than a single coil pickup through a Fender style amp. Then you gotta be able to play!
