- MSMichael S.Verified BuyerReviewing3+3 Ratio Electric Guitar Machine Heads (PRN-2311, 2341, please select finish and button style)I recommend this productRated 5 out of 5 stars2 weeks agoGreat!!
This might be obvious, but when installing, put the tuner into the plate before putting the screws into the headstock plates. If you put the screws into the plates first the tangs of the tuner might not fit well into the plate. The work wonderfully when installed.

Every guitar I put these on, it just makes it perfect. Much easier to change strings. The feel of the tuning needle slowing down in time and being able to tune with pin-point precision is just excellent.
