Thanks, Booli, both for the comment about the song, and about the Uke.
Nope, not a Riptide. It is the one Custom Built ukulele I own, and likely to stay that way. It is my Bradford Donaldson Concert ukulele, Port Orford cedar top, birds-eye maple back & sides. I took delivery of the uke in July 2013, and it is my favorite uke, hands down (Followed closely by my KoAloha Sceptre and Timms Soprano). I've got a K&K Twinspot in it, PegHed tuners, and a personal sound hole - and Rick Turner put the neck strap button on for me. While it was in the build process, I bought an Ameriitage Silver case from WickedWahine11, and had it shipped to Brad - so the case and uke fit each other perfectly.
Pretty much everyone who has played it loves it, including Sarah Maisel.
