Yeah, your cover shows impressively that you don’t need a “Dong Whale” or a “Bender” (can’t remember the actual brand names ^^) to get cool sound!
Maybe you can write a review for the Blackstar on YOUR Bass Reviews - and I add my comments on the modifications I made. Together we could provide quite some insights about that “Klein aber oho” (German for: “small but WTF!”) bass.
