I'm not completely decided, but I have this growing hankering after a set of MQs in the SG. I've never played P90s - but I grew up on strats and single coils. I've just got this feeling that the SG (which doesn't get played a lot, and seems a bit soul-less now with the Explorer's Gibson ceramic killers in it) might suddenly turn into something rather splendid and bluesy with 90's in it. Any thoughts?
Never tried MQs as such, but I have owned a couple of SGs with P-90s, and several LP Jr/LP Special types.
I agree with Twinfan, P-90s are great for clean to just-breaking-up tones. Very fat, but still with some single-coil character. With a lot of distortion they get too mushy, they simply don't have that tight crunch that humbuckers give for chords.
My LP Junior with a BKP-91 is one of my favourite guitars, but in the SGs I found there wasn't enough variation in tone between the neck and bridge pickups.
I'm toying with the idea of putting a MQ in just the
neck position of one of my SGs, but not sure what humbucker to match it with. And then again, a vintage-output humbucker sounds so good as an SG neck pickup, I'm worried an MQ might be an expensive mistake - maybe I should stick to the ain't-broke-don't-fix-it approach. :?
