Depends on your meaning of shit guitarist, If you mean someone that can strum a few chord and keep in time to a beat then yes they can, just as a certain piece of software called Autotune can make a shit vocalist sound amazing.
As for your other post, I really can't be bothered argueing with you about how good the Edge is, he is an average guitar player at best, but has the ability to co-write very popular and catchy tunes that sell to lots of people who don't give a shit about decent music.
1/In my experience a poor technical guitarist and one who has little imagination can make his work sound shall we say 'lifted' by outside additional help. Clearly if you play the instrument in any way at all you'd know that is not the case with the Edge or any excellent player, sure his trademark sound may utilise the delay pedal reverb but he's still got to play good things into it.
You'd also know if you've listened that even a "shit" singer cannot sound great utilising even the most advanced software, as good as autotune is, it does need some kind of 'performance' before it can really enhance anything
There is hardly any piece of audio hardware / software technology that will make any shit singer or instrumentalist "great". They can maybe 'save' a poor vocal here and there but as for sounding great - that's a myth - the digital changes required ( formants) to make changes wider than a whole tone affect the end result so much on a bad vocal it becomes unusable.
2/ As for my other post you wont argue about the Edge being excellent because I've outlined to you with examples that Greenwood although stylistically different does in fact often do the very same things. As I said I'm no U2 fan but this...
..."the Edge is, he is an average guitar player at best,...."
to quote your mate further up the board is one of the stupidest things I have heard .....ever
