Schaller M6 135 Locking 6L CH

I swapped these to my home-made strat over some cheap non-locking tuners. These Schallers seem to keep the tuning slightly better and changing strings now is a breeze. Since these are staggered, three of the tuners have the string entrance-point lower which helps to create angle to the headstock on strat-kind-guitars. This also means that you no longer need string trees after these are installed. So even less friction on your guitar.

I highly recommend this product.
