eric clapton- use the blues scale. and pentatonic. which is close to the same thing.

both of which are easy to learn and even easier to use. thats what alot of people use for improvs.


and keep in mind, alot of blues has to do with feeeel. theres a very certain feel you get when your playing blues. a constant rhythem that you should get with practice. but till then just learn those blues and pentatonic scales.
