Agree with Jack completely !
Your call - but to me 4 weeks is more than enough time for the seller to pull his finger out and start shipping the guitar to you.
Fingers crossed that he is trustworthy and just experiencing some problems and you do get your guitar (sounds like a great buy), but at this point I would be starting to put serious pressure on the guy.
As Jack says, inform ebay and file a Paypal dispute immediately. Sounds like you have given the seller plenty of chances to resolve this.
