NoahJames Guitars expands it product line to include precision parts, with the release of JENZ precision machine heads, heralding a major breakthrough in tuning gear technology for electric basses. Developed by music industry veteran guitar designer and custom builder, James Donahue, new JENZ machine heads are direct, drop-in replacements for the familiar open-back, elephant-ear-style bass tuning gears that have been standard equipment on one-piece-neck electric basses since their introduction. Donahues patent-pending, innovative machine heads address shortcomings that have plagued electric bass design since its inception. Turns out that threaded posts on JENZ gears are the secret sauce strings are channeled to anchor at the lowest point on the machine head post, improving overall headstock stability and also eliminating headstock bowing! Overall bass neck structural integrity is thereby improved to the point that many ailments common to one-piece necks are mitigated. First, string installation is significantly improved. Strings automatically wrap neatly and snugly around the tuning post without any winding error, so a string cant bind against itself and become prone to sticking or slippage. Second, the common predicament that many bassists confront the need for the truss rod to be maximally tightened to compensate for the headstock bowing due to its inherent weakness from being unreinforced is no longer the case because the headstock is kept straight. Third, since the natural tendency for strings to pull up on the headstock is reduced, unwanted modal vibration of the headstock that causes pitch warble, modal dead spots, and sustain loss is alleviated. Finally, JENZ gears also eliminate the need for pesky string retainers that contribute to unwanted modal vibration in the headstock. With JENZ machine heads, Donahues improvements to bass tuning gear design are evident in several key areas: easier string installation and tuning, better pitch accuracy and stability, fewer dead spot issues, and increased sustain. JENZ bass machine heads come with a limited lifetime warranty and are easy to install, and work with any bass strings with a tapered core -- regardless of gauges or wind types.
