That is the video! I watched a bit more, and Watt is really battering that bass towards the end! The tone reminds me of the Mustang that I used to own. There is a P bass grind to the top end, and a woofing low end, but the two don't always marry up very well, especially when played hard! This audio on the video is weird, as there are ambient mics in the room that are out of sync with the main audio feed. By the end there is an annoying pre-echo on the vocals. Probably not the best reflection of what the bass sounds like, so yeah I'm waiting for a demo video as well.
I'm still not used to seeing Watt playing such a clean-looking bass. I wonder if he will mod his personal Reverends, or whether he is done with all of that?
