I brought up this topic in the Mr Black OD thread, but after thinking about it more, I was wondering if others were experiencing the same thing so I felt it deserved its own thread. If I am playing thru my B3K for a while, I notice that when I toggle to my Black OD, the Black OD has, to my ears, a sort of hollow, nasally quality to it. But if I play only my Black OD without having used the B3K before it, it sounds just fine. It got me wondering if the baked in EQ curve of the B3K somehow "tunes" my ears and then when I go to a different pedal, that different pedal sounds weird. Not bad, not good, just weird. I also notice this phenomenon with my Big Game Bedlam, my Fuzzrocious Demon, My VFE Pale Horse. They just don't sound good after I use the B3K, but sound great on their own if I don't use the B3K. Just to be clear, I am not talking about stacking these pedals with the B3k. I am talking about toggling back and forth. Does anyone else notice this? The phenomenon bothers me enough that I never use the B3K and the Black OD in the same song. I do notice that some of my other pedals really sound fantastic (or at least not weird) when toggled back and forth with the B3k. These include the Dungeon Master, the Superfuzz, the Diabolik, the Static Fuzz and the Cool Buzz bass Fuzz. In writing the previous paragraph I notice that the pedals that sound, to my ears, the best with the B3K are all high gain distortions or Fuzzes. It seems only other lower gain, "natural sounding" overdrives exhibit this phenomonenon with the B3k, at least to my ears. If you have or haven't noticed this, perhaps there could be salvaged by listing pedals that sound great paired up (not stacked) with the B3K.
