Yep, that makes sense to me (and I'm guessing to other Blackguard owners as well). I didn't really know what the sound I wanted was, I wasn't even sure that it was possible, mebbe it was this mythical "tele" sound I'd gathered from various records over the years... but the moment I plugged the guitar in after fitting them it was... yeah, that's it... :D
I've just experienced a similar thing fitting Apaches to a Roadworn 50s strat. They weren't the obvious pickup choice for me, but they just seemed the obvious set to get for that particular guitar. And when I plugged it in it was "where have you been all my life!!... and why wasn't I looking for you?" :lol:
