My buddy has an Sg special, probably 1972-ish, with black mini-humbuckers. He's played it to death and I finally convinced him to put some needed love into it. Due to heavy strings the bridge is starting collapse and it badly needs a recrown. Ive never thought the pickups sounded very good but I haven't checked the pot values. Would he benefit from a new harness or should I start hunting for pickups? Would a Nashville TOM withstand the tension better than an ABR bridge? Below is a different but similarly spec-ed guitar. Given the fact that its not particularly nice or valuable, any input would be greatly appreciated.
