Not a ukulele band as far as I could determine – but it should be!
Here is De Faoite Stringed Instruments harp ukulele “Arch Uke Ferdinand”
David White says,
“The main neck is strung with Aquila nylgut Low G Tenor ukulele strings, and the sub-basses are D’Addario Classical guitar strings – 6th, 5th, 5th and 4th. I have the instrument in G C E F GG CC DD GG tuning. Here is a recording of me playing “Waffen Waltz/Ferdinand” in this tuning. The first piece was written by Chris Wood and the second is my own composition.”
