OVATION 1598MEII Details
The Adamas Ovation has been an integral part of Etheridge's sound throughout
her career. This signature model celebrates and honors that long association
of artist and instrument. Its mid-depth body with cutaway, carbon-fiber SMT
top, and quintad bracing creates an instrument with a bright, clear tone that
seldom feeds back on stage. The neck is two-piece dark walnut with Kaman Bar
support and an ebony fretboard. Gold Schallers®, single-ply white binding,
ebony bridge, and a ruby burst over graphite finish give it a very tasty, uptown
look. A Tru-Balance pickup and OP24 Plus C preamp give it true and trouble-free
amplified sound. Inside you'll find a special Adamas label, hand-signed by Melissa
herself. Hardshell case included.

Battery Replacement

The XLR jack featured on certain OP-Pro equipped guitars gives you a professional,
balancedline connection to mixers and high-end acoustic amps. The phantom power
capability allows your mixer to power the preamp. Any XLR cable with a ground-to-shell
connection (Ovation P/N 9658-0) is required for the auto power-on function.
A "dummy plug" (Ovation P/N 9659-0) inserted into the 1/4" jack
can be used instead, if the proper XLR cable is not available.
The 1/4" jack on all models provides an unbalanced, line-level connection
to most any amplification system. Inserting a plug into this jack also turns
on the preamp system. Please note that the tuner is functional without any connection.
