Greetings everyone! I recently got a Oscar Schmidt OE40, which is a L5 sized hollowbody that will be getting a set of L-609's soon. In the mean time, I want to try putting one or two sound posts in it to cut down on the acoustical feedback so common with hollowbody guitars. I once read somewhere that if a wood post is installed inside the guitar's body directly under the area where the bridge sits, uncontrollable feedback is greatly reduced. Does anyone out there have any experience or advice concerning this sort of thing?
