The Allparts tuner looks like it may be reversible, like the non-import Hipshot lite tuner is, as it has the hex-key bolt holding the tuning key in place. The body looks symmetrical. But it all depends on whether both sides of the body have identical machining to allow swapping, or whether the body comes in definite r/h and l/h versions. You’d have thought they’d have made something of it if they were reversible. But sometimes the obvious is overlooked.
