i am not sure why everyone is saying that guitar is easier. to become a virtuoso of the classical guitar takes just as many years as it does to become a virtuoso of any other classical instrument. while unfretted instruments do present the challenge of intonation, the guitar offers the challenge of multi simultaneous voicing. your fretting hand can be doing 3- different tings on 3-4 different fingers while your right hand is doing 4-5 different things, add to this two more strings than the violin and you get start to get the picture. if not, please listen to some of john williams (the guitarist, not film scorer) recordings of j.s. bach. jullian bream, christopher parkening, andres segovia and of course randy pile are guitar virtuosos. pepe romero is another. in the classical style reading notation is a must and getting good tone requires much more than amp and eq settings. i used to play electric all the time as well as steel string acoustic, violin, double bass and piano. the guitar is by no means easier unless you are trying to do easy playing. i imagine the same is for all the other instruments. virtuosity is not about the instrument its about the instrumentalist, as is mastery.
