Those two brands basses sounded pretty nice, but I've never heard of them. Atelier Z also has the problem of no distribution or high profile endorsements, at least in the USA, but they make a fine bass. I played a couple at NAMM two years ago and thought they had the goods. Good craftsmanship, they played great, sounded great. All totally available for purchase. But the "X-factor" (sorry Stu Hamm) is the hardest thing to put your finger on. If I were in the market for a "non-Fender" Fender, didn't want to wait for a Moollon, and I didn't need a "name" instrument for some sort of marketing street cred, Atelier Z would be very high on my list.
Big +1 on Atelier Z. I have a JHJ-189 and it is built to the highest standards available. They are on par with the
"S" and "L" and "AC" USA bass builders without question- I've had them all. IMO of cousre.
The Moollon supply/demand is amazing. I have no doubt they are 110% the real deal, and Tim LeFevbre is a great, great player.
It's amazing how many under-the-radar builders there are. I personally have a thing for the Japanese small-batch builders, even traveled there to behold, and behold I did!
Took home a Harry's Dragonfly.
Not to derail- The Reverb prices for a used Moollon shows how coveted they are. I can tell you that value is in the eyes of the potential owner. As in:
I had a Stevens Slant 4 that was the s***! My wife's Toyota needed a new engine.
Otherwise, I never would have let it go. Wait time for a Slant is 2-3 years as well, IF he's still going to build 'em.
I had a buyer seek me out-unsolicited-from Facebook (he saw my bass on Steven's site)- to buy mine. At first I said NOWAY, but then came the car repair bill. Plus- he offered me literally 2X what I paid for the bass several years back. Guess he didn't want to wait. (P.S. sadly he's a collector

) At least it will make him happy, and I fortunately have some other great basses.
Anyway, I would totally groove on a Moollon P-bass, no doubt whatsoever.
