Yep, it's a nice tone alright. Like you say, it's not often you see an EUB played by someone coming at it from an acoustic bass standpoint. I think this is a large part of the sound to be honest - if you play an EUB like it's a big fretless bass turned on its side then it'll sound like that, whereas using a DB technique tends to give a more DB tone. Having said that, I've never played an EUB so this is pure speculation on my part based on a limited number of videos I've seen....
