Support arms adjust in height 17”–24” to enable precise sound direction for a wide range of amps. Height settings are secured with tightening knobs and locking pins. Nonslip padding on the arms protects amps from scratches and increases traction to ensure stability.  Support arms and base legs quickly fold down flat for ease of load in, setup, teardown, and load out while also enabling compact storage and efficient transportation.  Durable black finish resists chips and scratches to stay looking new while unobtrusively blending into any stage or studio setup for a professional presentation.
