Just had them installed onto my Ramirezdel Tiempo and I LOVE THEM! Why?
First and least of all, they look beautiful and required only a minor adjustment during installation,
Second, they are very easy to turn and the precision reached is as perfect as I think it can be! What a difference from the Chinese Ping tuners that came with the guitar, which were hard to turn and difficult to get great tuning!
Geoff, as usual was extremely helpful. I asked him if he thought these tuners were good for my del Tiempo or if he had an alternate suggestion. He agreed these would work well.
Another comment related to the del Tiempo; it is a beautiful instrument well worth it's weight in gold. I was told by my luthier that he had a $10,000 guitar that didn't sound very different from the del Tiempo.
Hope this helps those of you looking at the Schaller tuners or even the Ramirez del Tiempo. Both AWESOME!
