I have a mahogany-bodied Telecaster with a canary/ebony neck loaded with a pair of Roadhouse True Blue [single coil] P90's, This Tele is a good deal quieter than my Strat loaded with low-output single coils taken from an Eric Johnson Strat. I have no extraordinary shielding installed in either guitar, except for the aluminum foil backing on the Strat pickguard. I find the P90's have plenty of bite, and plenty of output. They are a decidedly different beast from Strat single coils. The bridge P90 behaves somewhat similarly to a hot Tele bridge pickup, but with a little more bass & mid. They are tremendously responsive to change in playing style, and I can set my amp to medium gain and get everything from Knopfleresque snap to a nice Pete Townshend power-chord kraaang. They are plenty bright when wired with 250k tone and volume pots, but they'd be brighter still with 500k's.
In short, these are my favorite pups of all the axes I own.
I just took a look at the Roadhouse website (http://www.roadhousepickups.com ) and I don't see the True Blue set there anymore, since Ken's been winding a lot of repro Valco and Teisco pups but he has a variant he calls a P80, which has Alnico pole pieces instead of the adjustable metal slugs. I'd buy 'em if I were in the market for a pair of P90's, just based on my wonderful experience with the first set of Roadhouse pups I got. I would reach out to him to see whether he can wind a conventional P90 for you. Ken's a great guy to do business with, and is very smart and helpful when it comes to identifying what to do to help you get your preferred sound.
