Here's a wonderfully fun instrument I just finished. It started life as a lightly used Luna Starry nights travel guitar but has been converted into an eight-string instrument. Depending on the strings, tuning and musical style this can now be played as an octave mandolin, bouzouki, mandola, double-strung tenor or plectrum guitar, double-strung steel string baritone ukulele, a cello-mando, or even just a regular six-string.
Currently tuned GDAE as an octave mandolin, the C and G courses both have a high string tuned an octave up, giving the instrument a lighter echo that sounds lovely and produces sweet harmonic overtones. Playing absolutely beautifully with resonance and a solid boxy tone, this guitar sounds much better than when it had six strings!
The underlying guitar is a decent little instrument, in excellent, lightly used physical condition. Perfect low action, room on the saddle, working truss rod. Very nice cosmetically with a few scratches and small dings on the back, sides, and headstock.
I am happy to set this up however you like before shipping if purchased at the asking price, or for a small charge otherwise. There are a TON of different configurations this instrument can play in, and I'm sure you will think of more. For any given setup, I customize the string gauges as well, to ensure good playability and prevent overloading the guitar.
The conversion process entailed, among other steps, resizing tuner holes, fitting two additional tuners, adapting and fitting a nut, replacing and leveling the saddle, adding four bridge pin holes in the correct positions, and exploring various setups to optimize the instrument in this eight-string configuration. The original bridge pin holes are retained, so this instrument can be returned to a six-string configuration with just a slight nut modification.
Shipping available, fast, well protected, and fully insured. Comes with a basic Luna bag. Make me an offer!
By the way, I'm happy to do a similar conversion on your instrument, either something you already own or a model you buy new for the purpose. Not all acoustic guitars can easily accommodate the extra pins and tuners, but many can. Shoot me a message if you're interested!
