Here's a couple others: Mike Pereira http://mpukuleles.com/ makes a tenor pineapple, so does R&L 'Ukuleles http://www.ukuleleshawaii.biz/. I have a Koa tenor made by NICE 'Ukulele (made in Philippines, setup in Hawai'i) but no website.
The Eleuke tenor Pineapples I've seen look like they have a soprano body with tenor neck (Super-Duper Soprano?). Do they come in a tenor body size model too? Personally I prefer the smaller body but just curious.
WOW. This is pretty neat looking. If it were accoustic I would have to add it to my wish list. I was thinking of building something this spring. I may have an idea.
