i would definitely fit one of them will some humbucker sized p90s. since they are both humbucker guitars, it would make them a little different. maybe some Mississippi Queens
I very much agree with that. At least in the neck spot of one of them this would be really, really great. I personally am also a big fan of bridge P90s, but it is a less save bet for people to like than in the neck position. And a proper HB bridge / P90 neck position is incredible.
For the guitar that is middier (and/or muddier)I would go with the P90. I right now cannot make up my mind about what to best pair with the neck besides a P90 bridge so IŽll sleep on that one. But a MQ set is something that will convince a lot of people if they actually try it. Bloody brilliant pickup.
And if you wanne go Studio and versatile the other one would have to pretty much be Riff Raff bridge and Mule neck. Versatile beyond believe, fromclean, to crunch, to heavy, and oozing goodnes. Really a no brainer to have one of the two fitted with those.
