what ohter techniques can you use( like jimmy page's playing wiht a bow) to get some trippy sounds out of your guitar?
do stuff like the dude in Rage against the machine
a whammy bar? or a slide?
Get a Wah Wah!
what about something unheard of, like throwing a cat at your guitar, taht sounds funky
Personally i like to play guitar while someone defecates all over my guitar. I then proceed to smear the feces on the strings, giving them a smoother sound. Then I play Eruption, followed usually by me vommiting onto the floor.
