ermmm, dime the gain and stand close to your amp? Also throw in an od pedal with some gain on it also? Also really hot pups?
Get a nice heavy sound that you like and play for example an 'a' power chord and let it ring out rigt infront of your amp. Or hit harmonics in different places. It varies on many amps. You can hit a pinch harmonic and let it ring out into feedback and then continue to change the pitch of your feedback.
