yeah, like my thumb and the pick both touch the string. but i've noticed that the pinched harmonic sound actually comes easier, or sounds clearer, when you're playing on a better amp. I remember when i was playing on my friend's Mesa, it was easier for me. but maybe it had something to do with his gain...
Concurred. Pardon my Captain Obvious tendencies but a guitar that's not half as bad as, say, a Squier Strat tends to result in better "squeals", I've found.
