I installed this in less than a minute on a 70's vintage instrument. My first guitar was a Conrad Dove with a metal Tune-O-Matic Bridge. The guitar never sounded good but it had a sentimental value with a great action with the bridge adjustment. The Dimarzio Virtual Acoustic pickup system brought out the tones unlike any pickup system I ever tried. I look forward to playing this instrument at live events and telling the great stories this instrument has for me.
