This guy is not a happy bunny , but really it's his problem imo you stop learning when they hammer the nails in your coffin.
I've been plying for 30 odd years and can wrestle a tune out of my LP copy ( that is no doubt another sore point for our advanced player) , I get there in the end with my playing. However having had a look at this site and others I can see the worth of Guitar Tricks and will be signing up as soon as I sort my PayPal account out as I think I will learn how and why for the first time ever as I've never been able to afford lessons before. :)
