Im looking at getting a gauge, specifically this one. Not sure if it even makes a difference since units can be converted, but I wondered if there's an advantage one way or the other. I'll be using them to set up fender and fender-style basses. Normally I'd just go metric, but I've seen a decent amount of documentation with suggested measurements in fractions of an inch, so I thought I'd check before buying. I'd rather not buy both since they're a bit pricey and I won't use it that often.
