what is the fourth knob on the EGDM4k?
I'm missing the EGDM more than I thought I would. It would be interesting to see how one would interact with a 6G6-B type amp that I have now over the AC15 style amp that I used with my prior three EGDM's.
What a great pedal, worked awesome as a clean or dirty boost or as a low/med gain dirt all the way to full on distortion!
