Hughes & Kettner Tube Factor overdrive pedal


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.

Factor 1/2

The Tube Factor is a dual channel boost meaning you can set a clean boost or mild overdrive on the green channel and use factor 2 to kick it into serious distortion.

Here's what Hughes & Kettner say about the Tube factor:

Does your tone need a turbocharger? This dual- stage booster packs a mighty wallop, adding an extra kick that puts your sound out front. And the ingeniously simple Voicing knob lets you adjust the amount of boost smoothly from cleaner classic rock punch to dirtier modern-day overdrive. Try it and be amazed.
