I didn't always love my Moon bass.I have had it for about 10 years. I put on Nordstrand pickups and an Aguilar OBP1 and an ABM Bridge but even though it was extremely well made,I could never get it to play right.There was this clacking sound that it would make in the lower range. Root 5th or the 4th below. meat and potato range critical stuff. I just wasn't able to get rid of it. My other basses wouldn't do it, just this one.So I knew it wasn't poor playing technique.I think I'm pretty good at setting up basses but my Moon was a real problem. So it sat in the closet for a long time.
One day I decided put back the original Gotoh bridge that the bass came with and tried another setup. I sat down with it and gave it one more try before I was going to put it on E Bay. I don't know what I did, but the bass immediately felt like a different instrument. The clacking is gone, the action is low but not ridiculously low. It feels great, barely buzzes and it records better than the Atelier Z and sits in the mix just perfectly. It has a fat sound that is very clear at the same time almost keyboard like. But still Jazz bass all the way. My souped up 74 Fender Jazz used to be my favorite, followed my my Atelier Z 5 string Jazz, but for about 6 months now I have used the Moon for practically everything.
Sometimes I sit in my music room with my amp and I switch around between my basses. I have a cable with a silent plug, that helps. So I keep going back and forth, 74 Jazz , Atelier Z, Modulus Jazz, and my completely revamped former KSD Proto J,and the Moon (which has the 60s pickup placement).
All basses are totally dialed in and very similar ( I like the Marcus Miller vibe). I might change my mind at some point I don't know but for some reason the Moon has replaced my 74 Jazz as my best sounding instrument.
