Hipshot AStyle Graphtech Piezo Bridges
These Hipshot A Style Bridges feature Graphtech® Ghost® saddles. These can be used in combination with magnetic pickups or without. The piezo version of the A style bridge is generally the same, with the exception of a slot in the bass plate for the piezo wire to pass through as well as a differently styled saddle.
Graphech Ghost loaded piezo pickupslet you get acoustic tone from your bass when installed independently or used in conjunction with a Piezo Buffer circuit to bring the output to the correct level and incorporate magnetic pickups.
Custom-engineered piezo crystals are encapsulated in a set of Graph Tech's patented String Saver saddles. The ghost Saddle Pickups have a natural compression effect, so you can play as hard as you want without overloading the input channel or experiencing the dreaded piezo "quack". Pickups are individually calibrated, and sets are precision-balanced, so you get even string-to-string output.
A buffer is used to get the piezo signal to the correct level.

FAQ on Graphtech Ghost Pickups
Q:Can I file my ghost saddle to achieve a different dimensions or string spacing?
A:Do not attempt to file the notches on Ghost saddles!!! The piezo crystal is only 0.040" below the notch, and if you expose the pickup, the string will short it out and it won't work anymore. Furthermore, the pickup has been positioned optimally in relation to the string, so it may change the pickup sensitivity if you file the notch deeper. This will affect the string balance when you file some notches and not others.
Q:The saddle wires have 2 sides, which is which?
A:With our insulated Teflon wires (on all electric saddles) the blue side is ground and the silver side is signal.
Q: Do I have to use a Piezo Buffer system
A:Unless your bass is already equipped with a buffering system for intention of using Piezo pickups it is best to use a Piezo Buffer. Bartolini currently is one of the only manufacturers of a Piezo Buffer that can be used independently of combined with use of Magnetic Pickups.
