After using the single keyboard traditional stands for years on stage and in studio, I wanted to have something more stable, mobile, simple and fast to assemble for my recording studio and both on stage. I came upon this Jaspers 4D- 145B stand in the Thomann cataloque and immediately ordered it for my recording studio as a main stand for four synthesizers.
Once In a while I use it as a stage main multiple keyboard stand. The build quality is totally outstanding and the holders that came with are also super stable and can stand the weight of almost all keyboards or synthesizers out there. I've ordered a pair of Jaspers Holders 40B to be exact, and they fit exactly.
Some of the things I don't like about the stand is the hight distance of the keyboards. When the stand is fully stacked with keyboards, it becomes a bit difficult to read or program some keyboards with large front-to -depth during a performance due to the keyboard on top of the other. The LM key that got delivered with should always be around, otherwise, it might be hard to set up and tighten the holders.
