1000 Series (Original style)
The 1000 Series Original is the Korean-made version of the Original Tremolo, made to the same specifications and materials, but is available only to guitar manufacturers and can not be purchased aftermarket except for the Burnt Chrome finish. Parts for this system can be found here.
For identification, note that the German-made Original has a stamp on the bottom of the plate (logo side) that say "Made in Germany", whereas the 1000 Series has no markings whatsoever.
The 1000 Series Original can be found in both 6 & 7 string versions.
