While I agree that pickup placement is huge in getting a certain sound, one thing about Michael's sound is that his bass has a coated fretboard.
I know that coated fretboards can have a drastic impact on tone. And the fretless Zons that I've had did not.
I'm not saying you can't get a great sound from a non coated Zon fretboard but something else to consider.
Good point for sure.
What I am going on is having heard the bass in the picture in my original post and that is the overall tonal range I am going for.
