Actually I am perfectly fine with my Epiphone SG Special being a really cheap guitar, it's a pretty solid guitar, and with the right adjustments it both sounds and plays great. Don't really have anything at all to complain about but one thing, the stock tuning mechanisms, which in my opinion are of exceptionally poor quality, just straight out horrible. They cause the guitar not to be able to hold it's tuning very well and also makes it a chore to actually tune precisely in the first place. Therefor I am looking to replace the stock tuning mechanisms, preferably with something not all too expensive, while still being a noticeable improvement over the stock ones (honestly I have a hard time imagine any tuners on the market actually being worse), and preferably with some that can be dropped right in without extra drilling or filing holes bigger. So what are my options, what would you suggest?
