I've been playing a little more guitar lately, but my resonator (my only guitar) isn't always optimal. Just a bit too bright and dominant and too heavy.
I'm thinking about getting an Eastmann travel guitar used (this one). It sees this exact model is not available anymore, and I couldn't find any youtube reviews with prominent bass notes to decide if it would be good enough for backing up a fiddle. This is not a 12 fret body-style, but maybe the smaller body of a travel guitar would get closer to that sound than a dreadnought?
I probably won't actually use it for fiddle accompaniment that often. Most likely I'll end up using it for recording my own backing tracks, or practicing singing. Plus the smaller size would be good for my wife and eventually kids.
I don't know about the Eastman (looks nice though) but I've played the Baby and Big Baby Taylors, and they're very nice. Here's a recent video of a little Martin, in the hands of a good player: youtu.be/8WPuu7uNfDU My main guitar for the last 20 years or so has been a Martin 00-21, which has done everything I've needed. I think its not just the body size though, the 12 fret neck puts the bridge in a different place on the top, which makes a difference. Also I think the slotted peghead has some effect on the sound. We also have a 1927 Martin 2-17, a small all mahogany guitar that's amazing for its size. I think that may have been what Jimmie Rodgers used on his first recording session.

My main guitar for the past 6 years has been a 1950 00-21. The serial number identifies it as the very last guitar Martin recorded as having been made in 1950. I took a chance and bought it without playing it first. It was in bad shape, but you could tell from the photos, whoever owned had played it a lot - and must have really loved it. So - without hesitation - I bought it, and had it completely repaired and restored (but not refinished). The sound and playability of this guitar puts a smile on my face every time I pick it up. I have not shopped for another guitar since.
If you're looking for a smaller bodied guitar that outplays its size, I'd go for a Taylor GS Mini. I purchased one for my wife as she's very petite. Frankly, I love the tone of it over my fullsize dreadnaught. Its just a great sounding guitar. I think the back construction has a lot to do with it, as it has a little shape to it - not completely flat. I would not have any issue taking this to a jam.
They've been out a few years, so finding them used does not seem to be a problem, and they typically come with a great padded bag (much nicer than usual gig bags). My wife calls hers 'the nicest gift I ever gave her after the children!'.
I might have mentioned this on another thread but I absolutely love my 21st Century built Gibson L-00. It's a Custom Shop reissue made by luthier Ren Ferguson. It's made me largely put aside my two Martins -- a late 1970's M-38 and a 21st Century D-18 Golden Era. Compared to the Martins it is dry and midrange-y, but the sound has a simplicity and honesty to it that just takes my heart. It feels great in the hands. Intonation is well-nigh perfect. This isn't to say, though, that I spurn my Martins. The M-38 sounds refined and beautiful. The D-18 sounds big as all outdoors.
