Hello! Just bought my first PRS. A PRS SE Cu24. It was an 'New' open box item from Ebay from a Brick and mortar music store and authorized PRS dealer. Received it today but the bridge is lifted really high on the back, (like 5mm) and the action is really high. I noticed it only has 3 springs installed in the back. Did not comes with any extras. Will I need 4 springs? or can I lower the action with the 3 I have? Also it really won't stay in tune when using the tremolo, probably needs a good setup, or could the high bridge cause that?
