I have tried all of them except the 57s. I have recently installed a set of Burstbucker 1 and 2s in my Classic. It had the original Ceramic open coil pickups 496R, and 500T. I own 3 other guitars with the 490R and 498T set in them. One is a Studio with a chambered body, one is a 96 Standard with a solid body, and the third is an Epi Elitist which came with the US 490,498 set rebadged as 50SR, and 60ST.
I also installed an RS guitar works Vintage Kit with the Bumble Bee .022 Caps, wired 50s style in the Classic when I changed the pickups.
I really like the BB1 and 2s in my Classic. There is not a lot of difference in the output between the pickups.
I really like the 490, 498 combo in all of my other guitars. And would not change them. They sound really good and I like the extra output of the Briddge pickup.
I also have a set of PAFs in a 1990 ES 335 that may have been the forerunner of the 57 set.
I will post a little chart with the output of each one, and you can see where it is going.
I would recommend a set of 490,498s because there are lots of them out there and they would be reasonably cheap to pick up. A lot of guys change them out then regret it. Also the RS kit is a huge difference especially on the Agile. But remember the hole size is different for the Asian pots VS the US pots. RS mentions that on their site. It may require drilling out the holes for the pots.
I will give the DC resistance Neck then Bridge.
ES335 7.11, 8.76
Standard 7.66, 13.31
Classic with Ceramics. 8.32, 14.59
Classic with BB1,2 7.37, 8.07
Studio 7.50. 13.93
Epi 7.69, 13.39
I hope this helps. I really can't see putting a set of BBs in, since they are very close to the 57s. Unless you really want that tone.
The Blues is alright!
