Bought two sets of these to use the e, b and g machine heads on my Solar E2.6C G2. Unfortunately the "ears" are not made the same way as on the tuners that comes originally on the solar. Mistakes were made. But new sets from another brand are on the way! (will keep them out of this review because of obvious reasons).
Besides my little misstep I've used these tuners on other guitars and I'm very VERY happy with them. LOVE the trim function.
