I agree with Dan that Dave Rawlins style archtop sounds amazing for Americana. Epiphone makes a new version of his Olympic archtop that is pretty affordable. The acoustic pickup in it is pretty much garbage, but put a mic on it and it sounds fantastic. Archtop is a very niche sound, so definitely not for everyone. Another suggestion is maybe a 000 style Martin. My 000-18 is far less boomy than my D-18. Really sweet and smooth sound. And with the shorter scale, it'll be loads easier to play. And if another Martin isn't in your budget, I'd recommend a Blueridge. Basically Martin knock-off from China, but really well built. Solid wood options with pre-war style bracing. I have one as a travel/camping guitar, honestly gives my pricier guitars a run for their money.
