It's sold now, but earlier today Matt at World of Ukes posted a link to a very unusual Brüko instrument he was offering, a 3-string ukulele… I've never seen anything like it.
That was going through my mind too. However, some of what I play requires chords and that can include use of the fourth string. I suppose that for single note at a time melody picking - plus minor and major chords ? - three strings is enough. One Old Uke that I bought was set up that way, IIRC the g string was missing and I wondered about whether that had been intentional or not. A somewhat cheaper option than the £169 sticker price for the old Bruko, but as it sold there’s someone out there that didn’t think the price unreasonable.If you're more of a picker than a strummer, every re-entrant ukulele is only a 3 string instrument anyway. Not much difference.
Are you referring to Loog?I saw a 22" 3-string labeled as a guitar, meant to teach kids. It was in one of those catalogs that seem to arrive before the holidays (uncommon goods). There are no details like scale length and the neck looks like a yardstick (narrow). I'm sure it would work CEA, although maybe with string change needed. They also have an electric version.
