Jaspers 3M-140B

Bottom tier (Korg SV1)
Middle tier (Waldorf Quantum)
Top tier (Prophet 6)

I bought this for 2 reasons, it's height versatility, and to save space. I have used traditional tiers, and with a 3-stack of boards, it's very hard to keep them at playable heights. I usually set up 3 separate X stands when playing live. That being said, I bought this stand exclusively for studio use (no plans to ever move this to a live gig).

Most of this stand is built very very well. It's light and sturdy, wobble is very minimal. All of the metal parts are absolutely fantastic, Thomann shipped very fast. There are 2 major complaints I have with this stand.

1) Plastic Parts fail easily (serious issue!!):
- The keyboard 'arms' sit upon the front crossbar only. Tilt adjustments are done via plastic clamps on the side of each crossbar. There are small small plastic nubs (about 1-2mm large) that fits into a groove in another plastic clamp on the side. These wear out very easily. My Korg SV1 sits on the lower tier and is front heavy on the arms. When these plastic parts slip out (3 times), my SV1 rotates towards the ground. Thankfully my waldorf quantum keeps my Korg SV1 from falling out and hitting the ground. The system is fine in theory, but the plastic nubs should have been much longer. A further question about design intent: You can also loosen the keyboard arms themselves and rotate them, so I'm not sure what the real advantage (besides convenience) of having 2 different tilt points are. But maybe it would be best to leave the crossbars fixed and have the keyboard arms be the rotating point.

2) Lack of depth adjustments (more of a minor complaint):
- When I asked support about Depth/Escapement measurements they seemed confused. Took a few days, and then they gave me some vague answer. I should've have questioned further before buying, but they seemed annoyed. Not sure they really understood the question. It lacked a lot of specs online.

The only 2 depth adjustments are to either:
- unscrew the keyboard arms, and mount to the back hole of the clamp. This moves the keyboard backwards about 1.5"
- unscrew the keyboard arms and clamps and move to the back leg. This adjustment amount will vary depending on what height the keyboard is at.

I wish Jasper provided some more details on this product, their website lacks these details as well. I will live with this rig, as it's beyond it's returnable period, but hoping that Jasper will make appropriate modifications to their future stands.

I'm using it in my studio. Bought it so that I could put kinda heavy stage piano on the lowest shelf. So it easily holds stage piano + prophet + gaia.
Very stable stand, very versatile and easy to adjust. You can also buy extra holders if you have smaller mono/bass synths and put two on one shelf.
All in all, great stand for great price. Before buying I spent some time looking for best stand for my needs and I think this one is perfect. So if you're in the same situation that I'm, I highly recommend it =)

Able to gather all my gear into one place. Currently having some mdf shelves made for it, but to give you an idea of what I use the stand for and what each tier holds

Bottom; prophet 6, mackie profx12, sound card, op1
Middle: Dsi tempest, mpc1000, Dsi Mopho x4
Top: 2 x Yamaha HS7, moog little phatty

I added strengthening set (a single tube) on middle and top tier for extra stability and swapped out the included 30cm holders on the middle tier for 50cm holders so that the backs of the holders rest against the strengthening tube,

In general the strenghting bars probably weren't needed but I like to be safer that sorry and for ¤60 more I have that security.

Overall very happy as it contains my entire setup (excluding laptop) into a 150cm x 70cm space
