It simply doesn't come any better than these pickups. I have owned few vintage instruments and have played many Gibson's equipped with 50s PAF's, however with some of that old gear even though by and large vintage stuff is great it can also be a gamble as you can come across the occasional dud. Two different sources, very knowledgeable people, recommended these pickups to me and as soon as I strummed a couple of chords I recognised straight away "that sound"! Punchy, warm yet with enough treble which allows me to cut through any live or studio situation; just like the perfect PAF. Playing guitar pays my bills, so my gear is of paramount importance to me, and I have to say that these pickups turned my Custom Shop '58 Reissue into the perfect tool, which after having played it nearly every day for the last 4 years is now just as good as a real '58; and I know what I'm talking about.
