2 Channels The Fender Champion 50 has both a clean and dirty channel making it versatile and enjoyable to practice with because you can have a plethora of tones at your fingertips. You can go from clean to mild overdrive to heavy metal distortion all according to taste. Aux & Headphone Ports If you prefer practising with headphones and jamming along to backing tracks then you can connect your device with the Aux input and practice wildly into the night without disturbing the neighbours.
