I purchased some tuning pegs for a back up guitar, but i didnt want to spend more then the guitar itself (mexican strat). The Mex strat goes outta tune like a mofo, and so i purchashed Ping Precision Tuning Heads for about $30 CAD. Before i open em and mount em, do these suck? Im in no interest to swap bad tuning pegs for bad tuning pegs. What do u guys recommend? (i have used the search, and wondering if anyone has any additinonal input)
