The guitar I recently purchased and am extremely happy with, a G. Studio Session ETB, had normal tuners and have another guitar with locking system that teased me to buy these for her little syster. The simplicity and quickness once changing strings of locking turners is I guess try once, never go back.
Easy to instal, no extra drilling. Just a tiny line from the old turners you can hardly see and overall a perfect fit. Missing though some quick guide since I spent some time with preparations but as mentioned, extremely easy to instal even without instructions.
Good mechanics and overall quality, perfectly matching finish to a Gibson Studio Session Ebony Translucid Burst with those darker shine metal pieces. WOW! The first time I used this system, suddenly any quality locking turner did not seem as expensive since the time you spend with these is nothing. Thread, lock and adjust ...et voila...strings changed and staying more in tune. Again once you try, I think you wont go back.
Lets not forget Markos from the chat who clarified several other doubts I had on the guitar and this item to match construction and even color which is not the average you find in guitars. Thanks Markos
