How am I supposed to adjust the Pickup height in a Musicman Petrucci? No springs or adjustment screws like I am used to with my other guitars.
Looking at pctures on the intertubes, they seem to be direct mounted pickups.

So, if they don't already have some dense foam underneath, you'll have to take your strings off, unscrew the pickups and stuff a square of foam underneath. That will push fairly gently upwards against the pickup, acting like the screws from mounting rings.
