I spent half a day to try several guitars in my short list, including the streetmaster, Lakewood Black Sheep, a Taylor 324ce and some others like a mahagony Furch OM. All great guitars, but as soon as I played the streetmaster, I knew I was getting this one.
It has a warm unique tone, great projection, comfortable to play. Ordered it from Thomann the same day, great service from them as always. Put on new strings and adjusted the action. Very happy with the guitar overall. So a little bit more details:
Sound: It's subjective of course, but the streetmaster has a unique, warm sound which I loved the moment I started playing it. It also has great projection, sounds very loud. Probably the legendary adirondack spruce has a role here.
Playability: Very comfortable, especially after lowering the action just a little. Not super comfortable like a Taylor but still more than good enough.
Looks: The most subjective of all. Personally I'm not a fan of relic-ed guitars, but I grew fond of this one quite quickly. The finish looks good, not over the top. The vintage style tuners actually look really nice and complement the whole look.
Quality: This is the only part I wasn't satisfied. In general, the build quality is good. However, the finish is so fragile, it could get scratched if you looked at it too hard. So if you get one, make sure to handle it with extra caution.
