I'm sure many of you have noticed when browsing for Japanese guitars online that when they refer to the truss rod, they'll mention "there is a margin". Now, I'm sure this is a result of poor translation from Google, either that or there's something I'm just not getting. What does this mean? e.g. one guitar I'm looking at is described as having "a margin of about 60 degrees in tightening direction". As someone new to buying Japanese (got an E-LP-130ALS on the way!) I'm always happy to see mention of how much fret is remaining and what kind of shape the neck is in - something you rarely ever see mentioned in U.S. / Australian ads. Can any MIJ aficionados let me in on what this means?
