I've looked at the regulator heads many times but they really need to release them in coated white and vintage or even a DeJohnette coating. Something other than gloss white or gloss black.I am a big fan of the shallower drums, with a 12x20 that is a keeper. My favorite head setup for that (and just about all bass drums really) would be an Aquarian Force 1 clear batter, and a Regulator (unported) reso. I would highly recommend tossing the Ambassador and your muffling stuff, and putting a regulator on there.
With my 22x8, everything seems to have stayed the same.I think the science would be with us that the shorter distance between batter and reso should give them more attack.
