I now have absolutely no reason to ever buy a set of Spertzels ever again. I got seven of them in black chrome for my Jackson Stars, and they were a perfect drop in replacement for the Gotoh minis that were on there. Popped out the old ones, popped on the new ones. They have a wider ratio than Spertzels, so the tuners aren't so touchy when you're trying to make that string just a little bit sharper. They're shorter, so the string angle increases over the nut, giving me more punch and sustain. Every thing about them feels solid. Since they're minis, the footprint is much smaller than a Spertzel, too. FYI: If you like big strings, beware. I use a .060 on the bottom, and it took some persuading to make it fit. With Spertzels, you can drop the locking post out of the bottom and drill out the hole. The locking posts appear to be spring loaded on the Schallers, so I'm not sure how to widen the hole without damaging the top of the post. I'll try to post some pics tonight. They look really sharp and work great.
