Put these on my epi lp special, and what a differance. The stock tuners really sucked, was always tuning up and down hoping it would catch in the right spot, and stay. Never did. Realy like This guitar and love the p90,s.so went ahead and invested 60 bucs into this $99 new epi. Well worth it.this guitar is just a pure rocker and is p90 fun and then some. Late night playing with the honey tone, Surprisingly sweet set up. Planet wave lockers are great, and love how they just clip the string off. Read alot about how the e and b string have problems. No problens here. But when drilling i suggest going part way through from both sides with the drill. Or the headstock veneer chips. Mine did on two holes ,super glued the pieces back on. Good enough, and lesson learned.
