Here's a wonderfully fun instrument. It started life as a lightly used Yamaha APXT2 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, a double-strung tenor or plectrum guitar, a mandocello, a bouzouki or mandola, a baritone ukulele, or even just a regular six-string.
Currently tuned CGDA as a tenor guitar or mandola. Playing absolutely beautifully with resonance and clarity of tone. The underlying guitar is a great little instrument, in excellent, lightly used physical condition. Perfect low action, room on the saddle, working truss rod, working onboard electronic system. Very nice cosmetically, though there was a small amount of damage to the bridge which has been repaired and should not be of further concern.
I am happy to set this up differently before shipping for $25. 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 leveling the nut, replacing and leveling the saddle, adding and slotting four bridge pin holes, 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 ease.
Shipping available, fast, well protected, and fully insured.
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!
