I bought these tuners to put on my Ibanez ar2619 prestige which is already a guitar with excellent intonation and neck stability.
Although the tuners that came with it are Gotoh and good quality I felt they didn't do the rest of the guitars qualities justice so I decided to upgrade them and was sincerely impressed with the level of quality, like the title says "Smooth, stable and solid!".
In my 30 years of guitar playing and guitar tuning, I have never felt such perfection on tuners such as with these. Not to mention the installation is breeze and the esthetics are stunning.
They feel so comfortable in your fingers to turn and the precision is incredible whether your are tuning up or down. Honestly my guitar stays in tune for days at a time if there are no significant temperature changes in the room which have more effect on the wood of the guitar as opposed to the tuners.
So finally if you want to leave aside forever the inconsistencies of tuning machine heads, get yourself a set of these.
You won't regret it!
