Schaller M6 135 19,5 Locking 1R CH

I bought these individual locking tuners to replace the standard tuners on my Sterling Cutlass (it has 4+2 configuration on the headstock). They are excellent quality with a very smooth action which makes tuning very easy.

A quick word of caution when buying left and right tuners at the same time: the ones I was sent were slightly different so don't match perfectly. The locking buttons on the two right tuners were slightly larger than those on the left. I don't know if this is down to a new design or some other reason. It doesn't effect the functioning of the tuners, it's purely cosmetic.
