I actually used to play multiple instruments ten years ago, when I was in what equates to grade school, and even got pretty good at playing both Rhythm Guitar, Bass Guitar and Keyboard, to the point where I could've found a band and joined with ease, though I didn't really care about music back then. Then I got a depression and never touched an instrument again until a year and a half ago, where I picked up the guitar again and had to start all over... Now, I can play Rhythm Guitar somewhat well, and I've recently started learning to play piano as well (and I'm considering to pick up the bass as well), though it's going slowly. It's not hindering my progress, though. Just make sure you have the time to practice, and you'll be fine.

I must agree, though. I think Fenders are pretty easy to play. I don't own one, but the ones I've tried all have a curving fretboard, unlike the flat one I'm used to. I hate it for lead-playing, but it makes Barre Chords much easier to fret clearly (in my opinion, anyway).
