These are brand new! We had the factory make these in three heights- Tall, medium and short which allows you to create a pretty nice stagger- and should allow you to go without string trees for maximum tuning stability! A very nice new tuner made with the classic offset Gotoh style mounting system (10mm hole required) with a secure mechanical locking system. The knurled cap on the rear operates similar to the Sperzel tuners, but the locking pin is an integral part of the cap- So NO MORE lost pins!!
These are very high quality tuners- fully equal to the more pricey name brands. ($60 a set- really??) We have found tuning stability, smoothness and security to be absolutely GREAT with these tuners! These tuners have a 20:1 gear ratio.
