Hello! I recently bought a first generation K-7 in firespeak blue, which sports a LoPro trem (the one with 2 arm-holders for the u-bar). After setting up the intonation I faced a weird problem. The fine-tuning-anchor bolt (item labeled number 6 in the picture) sits too far towards the back and firmly touches the end of the cavity. I searched google and can't seem to find a guide mentioning the part and how to adjust it. Does this mean that the guitar cant be intonated properly?? I set up the guitar in standard B with 9s+ a 54. Thanks for helping!
