Hughes & Kettner Tube Factor MKII
Features
The Hughes & Kettner Tube Factor is a tube driven overdrive, boost and distortion pedal that can hot-rod your clean signal or push your dirty amp over the edge.
The single 12AX7 preamp tube will give you that lovely tube warmth that everyone loves from a driven tube amp. You can choose how much dirt you actually want on the signal with the Drive control while controlling the overall volume and headroom with the output control.
