ok so im talking ofcourse about this kind of stuff

how exactly does he get this sound, is it just a volume pedal and a lot of delay on a weird pickup,
or maybe some kind of midi or is it the amp?

i'm not a guy of effects but i've always loved this sound so someone knows?

Roy Buchanan did it with his pinky. I'm a big fan of Holdsworth stuff in the 70's. Saw him live in the mid 80's playing his synth-axe and was not impressed. You could use a volume pedal.
