Yeah, melodic soloing is pretty cool... using a recording device to capture the hummed or sung melody... then go back and tab out the notes. Usually, if you can sing/hum in key, the notes will be in a relative box of notes like a pentatonic or major scale... if you can find the root notes it's usually pretty easy from there. Learning other peoples solos is usually helpful... You already know the licks that they do... and it's no crime to steal licks... or alter them slightly... or use them at a different part of the neck or something. Every guitarist out there steals licks in some way or another... so try to inject some of dimes licks into your playing... try to put your own twist on the licks... Also, don't get super caught up in musical theory when you're playing... sure theory is there as the guidelines of what sounds good and right... But sometimes you have to go outside the box to make something sound better or different. Just keep plugging away. Good luck man.
