Just curious if there are any instruments with this scale that don't cost an arm and a leg. Of course I found the Kamaka Long Neck and also the Mele Jumbo Tenor but that's about it. Any others?
Yes, lots of inexpensive ukulele's with a 19" scale length. 19" scale is what both Bruceweiart and Taisamlu use on their baritone ukulele's. Find them both on eBay.
No your right. Baritones traditionally were 19". Many maker started making them with a scale length of 20"+ and the traditional 19" length became an odd ball.
