I've owned and played a number of LoPrinzi's and liked or loved them all except for one. I still own a soprano that's in my permamnent herd.
They have all had excellent volume with excellent dynamics and accessible tonal palettes, e.g., a range of tones were accessible with minimal technique and skill. LoPrinzi's tend to have a relatively low action and string tension.
I've only played concerts and sopranos, and I prefer the sopranos, but I tend to prefer sopranos anyway. I've played all mahogany, spruce and koa, and spruce and maple, and all cherry. The sopranos all had small bodies about the same size as a vintage Martin, except for the soprano I didn;t like which had a slightly larger body.
The soprano I didn't like was one of the new Model A cherry ukes. It just didn;t have that ringing tone I expect from a LoPrinzi, and the 3rd string especially just gave off a dead thunk. Probably just a lemon, but I was very disappointed. It was also, coincidentally, the only satin model LoPrinzi I ever played.
Anyway, the Loprinzi that's my keeper is a spruce and flamed maple soprano. Very strong voice with ringing tones, nice sustain and resonance, with lots of nice overtones - which is how I tend to like my ukes. It can also cut trhough other instruments easily so it doesn;t get lost in the crowd, so to speak. I have it strung in Aquila's with a low G (yes, there are sopranos that can take a low G very well indeed). I would characterize this uke as on the guitarish end of ukedom - the mahogany onestended to be more ukey. Porbably the spruce or maybe just some ukes are that way cuz that's the way they are...
Anyway, I highly recommend LoPrinzi's in spite of the cherry uke that I definitely did not like.
Now if only I could try a LoPrinzi soprnao with low G of spruce or cedar with rosewood back and sides...
