sustaining harmonics at moderate levels

[vette6600]

this may have been discussed, but i searched around and didn't see it, so;

i'm working on some satriani songs and have the licks, riffs, and melodies down, but whenever i get to a section with wacky harmonics like parts in "satch boogie", i 1) can't get them to sustain long enough and/or 2) barely get them to ring out intitially.

i'm playing through a pod xt live at somewhat quiet volume, and sometimes through headphones. is there anything i should tweak to help me acheive some more sustain? how much of this has to do with simply playing louder?

btw, the guitar is a 550 w/evos and the amp is a roland jc-120.

i can play, but lack in gear knowledge, so don't be afraid to point out the obvious stuff

usually his amps are kinda on the loud side so having the harmonics sustain for so long is usually a "feedback" type thing. You can try using a compressor in your pod to try and milk a little more sustain out of it but for the most part you'd have to play with regular speakers (not headphones) and play sort of on the loud side.
