I recently bought an Ibanez S1520 (used) with a lo-pro trem, but i'm having trouble getting the action as low as i like it. i've adjusted the two allen screws on the sides of the trem but i can't get it down any lower than where it is now which is still pretty high. how can i get it down lower?
have you checked your neck for neck relief? what string gauge are you using? is your trem parallel to the body?
If you can't get it worked out yourself, curb your ego and take it to a store and get them do it. Watch them, and you'll know for next time. And if they cant do it, then i have no idea whats going on.
You could put shims in the neck pocket.
