No idea what model Wal it was, doubtless the cheapest most basic they did, (second hand of course) just regular fretted passive (I think) 4 string thing, all plain black, I just thought it was absolute rubbish, it's the one bass that really sticks in my mind as hating it!
If you are slinging a 6string fretless, then I doff my hat to you sir! 👍
