I bought these tuners as a replacement for the default tuners on my Epiphone Les Paul Studio, along with the Gotoh GE103B-T TOM-Style Bridge G and GE101Z Stop Tailpiece G. There were no issues at all during installation. It's important to mention: check your screw bracket angle.
Needless to say, the new tuners have immensely improved overall tuning stability and winding sensitivity, and they look great on my Les Paul Studio.
