I am an official Kluson dealer now, so you can get the correct Kluson guitar tuners for a Schecter Dream Machine replica now in the online shop of my site.
During the Van Nuys era, Schecter used Kluson guitar tuners for their guitars ans basses. I have seen a lot of Schecters from this time with Schaller tuners but I guess that these were not factory-original. Remember that authorized Schecter dealers could assemble guitars from Schecter parts, and if the customer wanted Schallers, I guess the dealers put them in (Schaller tuners were common because they were considered as the best guitar tuners at that time).
It seems Mark’s Schecters all had Kluson tuners (it is sure for the Strats but I cannot say with 100% certainty for the red and black Teles as we don’t have enough high-resolution pictures of these). I personally like the Klusons better than Schallers, mainly as I love that the string ends disappear in a hole in the split shaft of the tuner.
Klusons were also the tuners on all vintage Fender guitars, before they were replaced with the Fender keys (labelled with a “F”) that were in fact manufactured by Schaller in Germany. The earliest Fenders had Kluson tuners with no label, from 1957 to 1964 Fenders had the so-called single-line Klusons, from late 1964 on double-line Klusons. The terms single-line and double-line refer to the “Kluson Deluxe” label on each tuner: both words in one line in the centre of the tuner are single line, while double line means one line for “Kluson” (left) and one for “Deluxe” (right). To my knowledge all Schecter Dream Machines had the double-line Klusons.
These tuners are still manufacturerd today.
