Great care has been taken in the selection of components and impedances to insure crystal clarity, wide frequency response, low noise and minimum distortion. As well, the unit is packed with useful features. Each unit comes with a 3 year guarantee against parts and workmanship. I've been touring the solo acoustic guitar circuit for fifteen years and have gone through many preamp, mixer and pick-up combinations. Not since I began using your Professional Master Blender have I been able to enjoy a consistent live sound.
