yeah - you can come close but you also have to understand a few things about the way he played...

1. his hands were VERY strong and he strangled that neck every time he played... if you can catch a video of him playing you'll see the bends he gets and he used heavy strings.

2. Stevie was constantly playing with his setups and equipment, tweaking them and making changes. So even if you get the same amp and guitar setup you'd still be missing a little something to replicate the sound.

3. Every guitar player sounds unique due to their skill, background, hand strength, angle of attack with or without a pick and then there's the whole mindset deal when playing.... I have a 50mb video of SRV doing Crossfire and he just gets lost in his playing.

best advice, if you have the cash, go get what he had, if you don't get what comes close. Most importantly, try to emulate him don't copy or you'll be just that (not that it's a bad thing) but think of it this way... do you want someone to say that you sound like him or do you want them to say that another guitar player sounds like you do!
