I must admit I'm quite interested in these.
I'm probably gonna try out a bridge Old Guard P90 in my Feline DC, and a nickel covered set of Old Guard humbuckers in one of my Les Pauls (the Stormies in there will probs go to my Explorer).
I'm not too worried I don't have some of the info I can get on the standard range... what I do know is Old Guard is "vintage" with AII magnets... and they're full-fat BKPs... that's actually all the info I personally need for choosing p90s and humbuckers at the moment. I would prefer it if the humbuckers had a 2-conductor option, but that's OK, I understand why they haven't, and I can cope with the 4-conductor.
I probably won't be trying the strat sets and tele sets because I prefer vintage stagger on strats ... and I've got more BKP tele sets than teles I like at the moment!
