A couple of months ago I discovered that in the 30s Martin built a batch of oddball guitars for the Paramount guitar company. They left the backs off, no sound hole, and added a banjo-style resonator back instead. I had to do something similar, just to see how it turned out.

So I made a concert scale camp uke without a soundhole from oak, added a koa and oak resonator back, and strung it as as 8 string taropatch with low/high G for the fourth string. And here it is:

The bridge is only temporary, to help me get the string spacing, and it needs more finish on the neck, but essentially done. Sounds like this:

Well, I like it a lot. I wonder, if anyone ever built a mandola or mandocello with a wooden top such as yours?

Neat. I would love to see/hear a sound clip.

I'm not sure what I am seeing. I'd call it a banjo mandolin or banjo mandola with a wooden head...but what do I know? Who cares how it is classified? I think it's pretty darned cool.

How do YOU want it to be classified?

So Chris, what did they call them back in the '30's?

Here's the headstock to answer you

More info at

http://www.vintagemartin.com/Martin30_Paramount_L.html

I think a wood topped banjo, also by Lange's Paramount corporation, was the inspiration, and in the UK Cammeyer made at least one. Info and pics at

http://www.yelvertonguitars.co.uk/banjo-restoration/

From these starting points I rather made it up as I went along!

Thanks for the links. So looks they were calling them resonator guitars. Cool, I really enjoy seeing these oddball vintage instruments - especially when someone brings me one to fix (but haven't got my hands on one of these yet).

I had a Cammeyer in my workshop a few years back. Sorry, no photos and I didn't record any more info - I was swapping the friction pegs for geared ones. The owner described it as "a cross between a banjo and a musical instrument". Sound was nothing special but he had it tuned down to Irish tenor banjo (octave below a mandolin) - it would probably have sounded better at C G D A tenor banjo tuning.
