I have an Epiphone acoustic guitar that I really like, my girlfriend gifted it to me after her uncle gifted it to her (she doesn't play, fingers are too small). It's the FT-130. It basically has two large screws, one on either side of the bridge, If anyone is familiar with this style of adjustable bridge can you please either tell me how to use it or send me a link to a site that will? the action is pretty low on the high strings and I'm getting a lot of buzzing (more than I should). Thanks for any help you can give!
