With the relocation of the company Gibson from Kalamazoo to Nashville the further development of the ABR-1 was celebrated.

The "Nashville" bridge has a significantly enlarged intonation range and a professional attachment with a 4mm to M5 threaded posts with M5 sleeves in the guitar.

Especially by using a tremolo, our Roller Bridges play their part perfectly.

Also the risk of string breaking is significantly reduced. Due to the rounded string support on the rollers, the bending angle of the string is significantly reduced and the strings last much longer.

ABM tailpieces have an eminent influence on the sound development and the sound transmission. All ABM parts are always milled from compacted metals with a homogeneous structure.

The ABM produces high-end Tuneomatic bridges for 7- and 8-string instruments, which show the optimum.
