Let me brag a littler bit about my 12-string. It's different, it's rare, and best of all it sounds great.

I have a National steel-bodied Delphi 12-string guitar. National guitar will custom build a 12-string for you for most models of their metal bodied and wood-bodied guitars for a 10% upcharge.

I play this 12-string resonator finger-style, and it is really wonderful. The sound comes off louder and brighter, due to the resonator, but without too much of the "little bells" or "chimes" sound produced by wooden guitars with their softer tones. It's hard to describe, but pianos have multiple strings struck simultaneously by a single hammer. The multiple strings are indistinct. What you hear is a piano. This guitar sounds less like a 12-string, and more like some completely different guitar, one that's perfect for blues and ragtime.

For example, the low base notes on the 5th and 6th strings almost sound like a tuba.

That's my two cents.
