Why you need the DynaMount X1 Robotic Microphone Mount:When on/off axis rotation isn't necessary the X1 provides a great alternative to the X1-R. It offers the same dual axis flexibility but with a smaller price tag. Not only can it be used to position a mic for tone laterally the second axis can also be used for phase alignment when multiple mics are being used on one source. It is a great for finding the sweetspot on guitar cabinets, bass cabinets, acoustic guitars, overheads, kick drums, pianos, cellos and anything else where mic placement matters.Dynamount
