These tuning machines stand out in terms of tuning accuracy (40:1), are well thought through when it comes to string change, and they surprise you with headstock looks that set you guitar appart. This set went on a reverse headstock Firebird model, reminiscent of the banjo style tuners, but with modern tuning stability. With these, tuning up a reversed headstock feels as familiar as a non-reversed, which is maybe important for those that do not like variant in the heat of a gig.
