Help: Steerling JP100D Koa

I recently purchased a Sterling JP100d Koa and am having trouble getting
intonation set properly. I have taken it to my local music shop for a set-up
from my local guy who works on all of my equipment so I trust him. Anybody
had or heard of any issues with this model ? Overall I love the guitar and p-ups.
any feed back would be appreciated. Thanks !
