Hi,
I always thought that if anyone is having issues with their guitar, they really needed to go listen to the really early "krautrock" stuff, and things like Guru Guru's first 3 albums (try Space Junk!), and then go look in the mirror. That and the family that went Neu! and prior to that, including Uli Treptke.
Sometimes creativity is just a person stuck in their mind and has nothing to do with the instrument. As a noted soothsayer said, you just need to get out of the way! But you can not be afraid of "noise" for "noise's sakes" and "fun"!
