Hey man,

Here's the better question to ask:

How long do you WANT it to take? two months? 6 months? a year? 3 years?

Whatever limit you set in your own mind, that is how long it will take. ;)

OR you could seek out a serious, experienced teacher. I mean, a really good one, that will help you learn to play like Jimi Hendrix in a matter of months.

I've been with my teacher for 9 months now (started from absolute beginner, at least left-handed, and couldn't a single note or song) and you can hear the result at my website... That's how long it takes. xD

I DID play right-handed like half my life, but I switched hands when I started with my teacher... Doesn't really matter though!

BUT I can't stress more that you need a really, really good teacher. That may cost quite a bit of money...
