I would guess that since the Kala KA-SMLT is a new model, there aren't a lot of us out here who've played it. Having said that, and anyone can jump in here to correct me if necessary, just getting the ball rolling, if you want a warm tone, that might not be the best choice. The HMS website says that the KA-SMLT has an "articulate spruce-like tone", and since I understand that spruce can "brighten up" warmer side/back woods, I would think that it wouldn't be particularly warm. (Yes, there's a sound sample, but everything sounds the same to me.) Of course, the right strings can tweak that somewhat. Ponos are great. It would be hard to go wrong with a Pono, and I say that as someone who owns both Ponos and Kalas. Also having said all of this, I have been mightily tempted by the KA-SMLT in the last few days......
Yes, yes, I know, no help whatsoever.....
Let us know what you decide, and welcome!
