The 4 knob DRD is a product of the original way Bjorn made the BJFe DRD. It was 3 knobs but it also had the lowmids control attached to the drive knob in reverse – so you got a beefier clean/low dirt sound and it tightened up for higher dirt settings. The new M control does all of this but also lets you use it in other ways to push the DRD into fuzzier territory or use it as an EQ for cleaner tones – a little mids can go a long way …… also has the red sparkle paint job and gold lettering.
