Why bother playing guitar?
My local musical instrument shop (see www.music47.co.uk) has changed over the past ten years or so, from one that used to be mainly classical instruments and sheet music, to one that is now mainly electric guitars and sheet music. The shop now has a specialist guitar section (see www.onlineguitars.uk.com) that seems to dominate the floor of the high street shop.
OK, so electric guitars have become more popular in the British popular music scene, and now it seems that every teenager (and 20-something) wants to play electric guitar. This is not quite as bad as everyone wanting to be a sound engineer, because at least there are quite a few young bands around each of which could absorb two (and a bit) electric guitar players, but there are very few sound engineering jobs.
I would have thought that (other things being equal) if you wanted to enhance your value as a musician you should learn to play something other than a guitar. Maybe you should forget the electric guitar altogether, and learn the electric violin instead.
I know this would tax the musical talent of most would-be guitarists, because there are no frets on a violin, so you would have to actually listen to what you are playing in order to get the intonation as you want it. Also that damn violin bow thingy can be so difficult to control if you have no muscular discipline.
However, the up-side is that if you can play electric violin even half decently, using a bit of reverb to fill in the holes in the music, then you are almost guaranteed a high-profile position in a band, and you can compete on equal terms with an electric guitar because the violin bow gives you a fantastic sustain.
