How did you find them wired each one in parallel?
Overall, same "defect" I found in series, too scooped, less bassy in parallel than series, and zingier, but only in the highs (while hi-mids still remain poor). I also tested the difference between active and passive with all combinations and passive is more detailed, everywhere, but most notably in the highs/hi-mids. The VariMid, while not producing annoying volume jumps (nor EQ bumps if you have it set flat), is definitely making the signal less nuanced, timbrically speaking, as if "losing resolution" somehow. I like what the VariMid DOES, really helped me tame the tone of these pickups (once already in single coil), mainly by adding mids. Don't know what frequency I'm boosting, not how much, I use both mids and mid frequency between 2/3 and 3/4 of the way, adds clarity/presence/intelligibility. I just don't like it seems to not treat the bass' timbre that good, which I'm sure added to the original series wiring genericness of these BH2s.
