Schaller F-Series 70s 6L NI

I put these on a Greco 70s strat and wish I hadnt. The original were of much higher quality. These feel, sound and are made of plastic parts. They hold tuning but they are very sticky and not the upgrade I hoped they would be. Unfortunatly I drilled out all the holes for these tuners so I am stuck with them. I though Schaller were the best quality but here not. Evn after the 2 years or so they have been on my guitar they still are very sticky when turning. They do look good though and they do hold tuning. I have a Japnese Tokai silver strat strat with replicas of these pickuos and they are far better. If Gotoh made these tuners would be different story. And 60 euro is not cheap for set tuners .
