View Full Version : Squareneck Resonator Mandolin?

Hey,
I just had an odd thought. I wonder if anyone has ever made a real Dobro in mandolin scale and tuning? I've seen plenty of roundneck resonator mandolins, and a few reso-OMs, for fretting or playing with a slide, but never a squareneck.
I don't know if a mandolin would have enough sustain to really work as a Dobro... It might sound cool, though.
I also know next to nothing about Dobros-- they are usually in an open tuning, aren't they? Would there be any advantage or disadvantage to having a mandolin family Dobro?
If you have it horizontal, facing up ala Dobro, I suppose there wouldn't be any penalty for having a wider neck. How about a resonator cittern in CGDAE?
I suppose there's a reason I haven't seen one of these before... may be like reinventing the perfectly good wheel.

Dobros(lap style, that is) tend to lose what sustain and warmth they have the futher up the neck you go. I think a lap-style mandolin would combine the worst aspects of both instruments.
Of course, just because it wouldn't sound good doesn't mean nobody would want to play one...

Once you get DAS invented I'm sure it would be a big seller....

Had a Rigel made Reso mando for a while , he used a Spider Bridge type ,
probably make another one, on order..
as opposed to the National RM1 that uses a biscuit bridge
nothin' square necked about either of them .

Here I go, hijacking my own thread again...
Take a look at this one (http://gryphonstrings.com/instpix/31328/31328.php), at Gryphon Strings. A round-knecker, but a beaut.

I have that exact same Dobro mandolin, only considerably more beat up. I love the stars-and-crescents coverplate.
Dobro and other resonator guitars played Hawaiian style, high string action, "fretted" with a steel bar, are generally tuned to an open chord. Standard bluegrass tuning is GBDGBD, low to high. To emulate on a "Hawaiian mandolin," you'd lose the advantages of "fifths" tuning. Also, I'd see little advantage to doubled strings on such an instrument (although Tut Taylor did play 12-string Dobro at one time; I have the World Pacific LP -- he had the four lowest strings tuned in octaves). What you'd probably end up with would be something like an octave-higher resonator guitar, with little bass.
Also: mandolin frets are considerably closer together than guitar frets, especially as you go up the neck. A "Hawaiian mandolin" would require some pretty precise steel placement in the upper registers; no margin for error there.
There's a picture of a Randy Wood 4-string resonator mandocello (tuned CGDA, octave below a mandola) on p.2 of this thread. (http://www.mandolincafe.com/forum/showthread.php?t=47793) It has a "round" or "Spanish" (old guitar terminology) neck, to be fretted rather than played with a bar.
My suggestion would be to get a cheap mandolin, raise the action by getting a high nut made or using a nut extender, and experiment with playing it "Hawaiian style" with a Stevens bar or some such. Try different tunings; maybe take one string of each pair off. If you experience a cosmic epiphany and decide you've found your dream instrument, betcha someone will build you a resonator version.

For the Dobrophonically curious it is amazingly easy to turn any old flattop guitar into a lap slide. The fretboard can be warped or even missing frets, you just raise the nut and buy a steel, and string it up with a heavier open-tuning set (don't use your fine guitar for this.)
Paul Beard at Resophonic Outfitters has lots of neat accessories for these conversions.
