Jaspers 4R-150B

I use Jaspers 4R-150B for housing all my current home studio. In the lower rack lies a 28kg Korg Triton Extreme 88. In the rest racks lie four sound modules, a mixing desk, Midisport 4x4, a 21" monitor, a laptop and a Mininova leaving enough space for even more.

The stand is unbelievable light and rolls on its wheels with no difficulty even when loaded. It is also very stable.
Assembling is easy and quick and doesn't take more than 10 minutes. Mind though that you should spend some 15 minutes more before you do it in order to be sure that you assemble it right and as your needs impose. Expect no help from a manual or from Jaspers website. In the box there is only a generic photo and a couple of words that don't give any serious hint.

The holder stoppers are lame. They are from plastic (why Jaspers?) and although they can be easily replaced there are no spares in the box you receive. Two of them came to me broken and Thomann has no stock of them so they have to call Jaspers. You will receive some spare adhesive felts which will come handy sooner or late since there not of the highest quality. Two of mine came damaged.

Pros:
Lightweight, easy assembly, sturdy, good quality wheels

Cons:
Plastic (!) stoppers, a bit pricey, no assembly instructions

In general I think you won't regret buying it although a few minor changes would make it even better.

In the link below you can find a very interesting article of Keyboard magazine and also some assembly help:

I bought the Jaspers 4R-150 with the intention of using it as a 3R stand, where the second tier would have additional support as per first tier. A spirit level is needed to properly arrange the assembly without frustration. Be careful to double-check your work before placing your machines, there are many points to tighten. Once assembled, the unit is excellent. I used shelving material across each tier with a 90 degree bracket on the front edge of each shelf to stop machines from sliding. With appropriate shelves and support, you will save money on the extra brackets for each piece of gear.

Typically brilliant stand from Jaspers with all the sturdiness and rigidity you come to expect from the leaders in keyboard stand technology.

My only quibble is that if you set the bottom tier to the lowest possible level, the 60cm arms no longer reach the rear support bar and Jaspers don't supply locking rings for this tier, so have to be bought separately otherwise you may find the keyboard tipping if it's a heavy one.. If Jaspers supplied these as standard, or featured a pair of 70cm arms, this would be perfect.
