Schaller / OFR intonation problems
Intonation problems could happen if you are swapping between a Schaller and an OFR system on a Jackson or Charvel guitar. FYI: Jackson and Charvel guitars, factory fitted with Schallers have the posts positioned 1/16" closer to the nut compared to the OFR fitted guitars. So, after replacing a Schaller with an OFR, you typically move the saddles slightly back on the OFR away from the nut. Drop tunings can be an issue so beware you may run out of saddle travel.
