Schaller M6 90 Locking 21,0 3L/3R BC

This machine heads I bought to replace broken Gotoh machine heads (about this accident with shaft breakage, I wrote in review for chrome variant of this machine heads). Great thanks to Thomann for fast shipping and delivery.
Pros:
1. Perfectly fits on any guitar, with previously installed machine heads with 90-degree screw bracket
2. Guitar always stays in-tune, even after a heavy playing on it
3. Large (2mm) hole for a string on shaft, which allows to set strings up to .079 gauge without increasing hole diameter with drill ( its another stone into Gotoh's garden, with hole diameter 1.8mm on a shaft)
4. Nice look and handy string locking screw head, that doesnt spoil the machine head appearance.
Cons: None found.
As I said on other review -- If you want to buy best for your guitar -- buy from Schaller.
