The Z-12s coming out of Dean Coy’s dcskunworks are not official G&L instruments. However, there are enough famous examples out there it is worthwhile the contraption used to get 12 tuning machines on a headstock combining 6 G&L branded Schaller tuning machines with 6 LSR Precision Tuners. A great solution for a 12-on-a-side configuration as can be seen on my Z-12 ‘Big Red’. These LSR tuning machines employ a similar string anchoring principle as can be found on the early Paul Reed Smith tuning machine (see e.g. my Artist II): a rotating cam grabbing the string in a channel. In this way it also acts like a locking tuning machine and not many turns, if any, are necessary to get the string to pitch.
