I also came across this same cool clip and was going to post it, but I saw it was already posted here.
That sure is an Epiphone EB3. I had one for two months or so and I really liked the sound of it. It is a good bass and it plays very smooth as well but unfortunately it has terrible neckdive. But it is amazing what you can buy for less than 300 bucks. It had to go because I bought an '68 EB3.
Did anyone try his Epiphone Rumblecat?
