I have 7. And I have only been playing for 8 months (a confession, not a boast). Here goes…
VTAB EL-55 concert. Not my first uke, but the one I bought after the cheapo soprano starter (since given away to a good home) when I realised I really liked playing the uke. Currently restrung low G - it brings out the bassiness which was always there.
Enya EUR-X1. A round camp-style soprano uke made of HPL, bought for cheap. Really well-made but quiet. I experimented a bit with strings to increase the volume, but it’s still kind of a novelty.
Snail UKT-528. So far my only tenor. At first I played this a lot, but it got displaced in my affections by others. Now it’s restrung with Aquila Red low Gs, and it’s back to being really played.
Cort UKE-BWS. My first solid wood, and a soprano. I absolutely love this one unconditionally. It gets played a lot, and it feels so comfortable and familiar.
Noah mahogany and spruce pineapple. This took some getting used to, I and I went through a few different strings before settling on Martin fluorocarbons. I like it, but I have mild intonation issues.
Flight NUB310 baritone. The first uke I bought from a shop in person. I just fell in love with the sound. And it is really good to have something different.
Uma UK30ST. Solid acacia concert, by most beautiful uke. The second one I bought from a physical shop, which involved a special trip. I love it.
UAS is currently dormant, but I can see solid wood tenor and baritones in the future, and maybe another soprano. Okay, not dormant at all, but I can wait a few months now between acquisitions.
