Allen & Heath ZED60-10FX Multipurpose Mixer With FXThis mixer is a guitarists dream. Two of the 4 mono channels have high impedance jack inputs that can take a normal line level or a low level input from a guitar pickup, so guitars can be plugged straight into the mixer without the need for DI boxes. These inputs have been crafted to recreate the sound of a classic tube preamp in a combo or head amp for incredible definition and warmth. Two stereo inputs are provided for MP3 CD players or keyboards.
