I have a Martinez round-neck respohonic. I've set it up with heavy strings and a raised nut so that I could learn dobro technique. Tuned to GBDGBD, it's been great for learning; but at the end of the day the sound is not the nasal dobro twang, but a more steel string guitar sound.

What gives the dobro its distinctive timbre?

What kind of cone is yours? The dobro sound comes from the spider bridge and inverted cone, or spider cone. If your's is a biscuit then it will never sound much like a dobro. Biscuits have less sustain, more punch, very little "twang", and are bit more banjo-like.

Without disassembling it, I wouldn't be able to tell. (Maybe not even then...)

The spider bridge has 8 leggs. They can be seen through the coverplate. Here is a biscuit bridge guitar cgi.ebay.com/DOBRO-RESONATOR-N...m63.l1177

I looked online for Martinez and couldn't find anything but accoustic guitars.

There are some examples of Martinez resonators at the bottom of this page. As you can see they offer biscuit style and dobro/spider-cone style guitars. Generally you can tell quickly and easily by the cover-plate -- the biscuits on top have the slightly smaller sieve style coverplate, and the large round wooden biscuit is visible under the palm rest. Most inexpensive dobro copies have the larger "fan" style coverplate and usually the distinctive round screens for sound holes, and if you look inside you can see the legs of the spider bridge and the speaker-like cone.

Ok. Then it's biscuit I've got. I got mine from Gladesville, too.

There you go then. Biscuits can be good guitars for finger-picking, rhythm and bottleneck slide, they're regular blues machines. As you say, its been okay to learn on but I'm afraid it will never really sound like a dobro, its just a totally different type of cone.
