Review: Tuners that look & work great, and they are affordable too... - Very good looking machine heads, they do seem to be very well constructed, they all turn very smooth and precise, I was worried as some reviewers mentioned that the high E and B strings could slip, so I did check the end of the pin and they all looked fine to me, installed them on a IYV IP-300-TSB guitar and they have been working fine for over a week, no tuning issues, they look really nice. I made sure to get the correct version, so they were a perfect drop in, so install was a breeze, I am so impressed that I am going to get a set for Strat (2 pins instead of screws for affixing to the headstock) and put on my MIM standard... if all goes good, I will also do it on my Tele... Re-stringing the guitar took a couple of minutes for all 6 strings, and with the strings being cut very close to the peg, the headstock looks very clean & tidy. No need to pay for the brand name, these look & work great, and the price is very good.
Review: Great value - I have these on 2 of my guitars, one is an SG clone, and the other is an Ibanez electric acoustic. They're great tuners. Very smooth turning, holds their tune a lot better than stock. Very easy to install.
