I don’t know how common it is. But found a video on youtube " Metallica - For Whom The Bell Tolls (Bass Cover) (Play Along Tabs In Video)" This is my goal to play at some point as it is awesome.
Odd bass! Looks like a new take on the Warwick/Spector body shape
Could be the other way around and Spector cloned this one, hard to say, looks like Washburn has made them for a while.
I think Its due to it looking similar to Josh’s Peavey. But its not. It has jazz pickups. though the pattern is fairly popular
Fully agree! Godspeed and good luck on your quest!
