The title pretty much explains it, its a string thru body to a tune o matic bridge and i cant figure out how to adjust the action. someone tell me the proper way?
You use the thumb-wheels on the support posts to screw the post in or out, for down or up. But check that the neck relief is right before you adjust the bridge.
Tony Doneby neck relief you mean check for any back or front bow and adjust the truss rod accordingly if needed, before messing with the bridge?
Yes, exactly. There should be a very slight front-bow at full string tension. There must be plenty of Youtube vids on setting neck relief if you don't know how to do it.
