The K&M 18866.000.35 keyboard stand (Sweetwater ID: SpiderProBK) or Baby-Spider Pro can be upgraded in minutes. You may now add an extra synth, piano, organ, or dedicated controller to your setup without switching stands. These support arms are the same as the Spider Pro series Type B tier (15° tilt, with "ears"), giving them a professional, uniform appearance and reliable support. The process is simple: remove the top retaining bracket from your stand, install and move your new tier into place, then replace.
