So, you see me play primarily two ukuleles in my videos, sometimes you see the third, I own three. A soprano, concert and tenor. I primarily play my soprano because I love the sound, it sounds like an Ukulele is supposed to sound in my opinion. My concert is my road warrior and the one that amps up, when I play with a band that is the one I use. Lastly my Tenor, lows Gs for my OGs, for sure the one I play the least (but recently the Ukulele I pick up for my post teeth brushing before bed 15 minute jam). What about you? What size do you play and why?
