Okay, so I've read all the threads, reviews and endorsements and have lived with the Suhr bpssc (used with custom shop 69's) for about a month now and I am pretty much satisfied with it. I am not satisfied with all of the breathless reporting here and elsewhere about how the tone of the pickups is totally unaltered. I don't know if it is just a case of the emperor's new clothes or if people just chose not to hear it, but the backplate system definitely takes some of the low mids out of the signal and leaves a bit (just a tiny bit) of metallic zing on top of the signal. It is really apparent on finger slides up the wound strings. Again, the sound is actually still quite good, and the hum reduction in my music room (transformer box in the yard, right outside the window) makes the bpssc essential for my strat, but the change in tone is definitely there. This is an objective observation only, and the tone I have now is still a valid strat tone, no doubt about it, but it is not identical to the tone I had without the backplate. Any new thoughts on this???????????
