In the back of my head i always just thought the super duper would have a really cool open raw tone to it. I know with the bor boost cranked and amp volume down, it sounds great. Having the master on the SD would do that i suppose, but may be too bright.
Oddly enough I just came back from my rehearsal space and just had a Super Duper revelation. I usually set my AC 30 clone clean with cut all the way off and volume on the top boost channel at about 9 oclock. I have been using a Tim pedal to get my sound to be as similar as possible to the AC 30 on about 1 to 2 oclock. I always left the first channel of the super duper on at about 10 oclock (unity) to clear up some mud and pump the signal through pedals and cables. I A/Bed tonight with the the second channel on about five o clock, master at 1 to 2 oclock and first channel at unity. It sounded way better with added clarity to my Gretsch (which had a problem with clarity) and was even better then my top boost volume on my sweet spot of two oclock. Just way punchier with more ring to chords. Get it!
