Tech's calibrated & synchronized tuning system makes tuning and re-tuning
your bass faster and more intuitive. Tuning on the fly has never be easier! Each
string position has it's own calibrated gear ratio, so every string feels and reacts the
same to any tuning adjustment.
One
full rotation of any key results in a one full tone pitch change (give or
take). From Low E to G, the gear ratio's are 48:1, 36:1, 25:1, and 23:1.
In
order to achieve the higher gear ratio's, Ratio's are the world's first machine heads using a double envelope gear design
with a hardened steel gear. Amazingly smooth and super strong.
