simply perfect

smilzo.72 04.09.2017

probably the best machine head with that classic shape, lightweight with superior tuning precision! a must have upgrade for those new fender basses with "vintage" style reverse tuning machine heads!

Great light tuners

Anonymous 23.02.2015

I bought these tuners to put them on a DIY '59 P-Bass. I wanted the bass to turn out really light, and the fact that these tuners are about half as heavy compared to regular tuners of the same shape helped a lot. The quality of the nickel plating is impeccable, and the tuning stability you get from them is great. They also work very smoothly, much better than even more expensive light vintage-style tuners from other brands that I tried. Overall well worth a shot.

Vintage Stability with Modern Smoothness

MaxFacha 01.12.2025

They deliver a vintage aesthetic with far more modern precision. They turn smoothly, hold tuning even with temperature changes or aggressive playing, and add almost no extra weight, which helps the overall balance of the bass. The build quality is consistent and noise-free. There are no flashy features, but in pure stability and feel, they outperform most cheaper alternatives. These are tuners you install and immediately forget about.
