I have an "old-specs BGF50s" (now BGF52) in my MiJ Custom 62 RI Tele and the result is just magic. Less output than something like the RY of course but still able to drive an amp (these 50s Tele pups were not shy), jangle and bite a-plenty with still a nice growl and weight, and... well as far as I'm concerned these are THE perfect Tele pickups set :happy:. Works wonder for blues, blues-rock, 50s rockabilly (obviously), 60s rock, 70s rock, hard-rock (yes they do hard-rock), punk-rock (the mid/late 70s kind), pub-rock, well, TL;DR: they rock !
But the (new specs) BGF50s might be a good choice too if you want a bit more output and beef.
