Not acquainted with Jeffery yet, unfortunately, but he does have a great website. Man, does that Dude travel!
Looked for some good photos on the site that could be enlarged.
Found one on his Press kit page and one on the Photos page that showed the engraved brand on the keyboard side. Both instruments said Bon Cajun.
Compared the photo on the website with the YouTube photo. 99.9% sure it's the same box.
Looks like he also plays a Gab 3-row.
Went to Mr. Larry's site and pulled up his phone and address, etc.
Pretty simple.
Thanks, Jude.
