So I bought this a couple weeks ago and I mentioned it very briefly, but I picked up what is effectively a modded Goldpoint attenuator from Mojo with a couple extra bells-and-whistles:
In addition to having more volume range on my amp, sounds seem to have noticeably more texture. My guess is that this has nothing to do with the attenuator and everything to do with just getting my levels to a good place, but I can’t really verify that.
