Re: Kent Armstrong Pickups?
I fell in love with p90's because of a pair of Kent Armstrong Sky pickups (his even cheaper korean OEM line). They came stock in an Ibanez Talman TC620. I replaced the bridge pickup with an actual Kent Armstrong P90 stack style humbucker, to get rid of the hum. It still was pretty cool, but not quite real P90 sound. My love for the P90's led me to buy a Les paul Special double cut, with real Gibson P90's, and I haven't played the Ibanez in 4 or 5 years. The Gibsons seeem to have more of everything I like about the P90 sound. My only complaint is the hum when I'm in the studio.
To sum it up, the Kents seemed pretty good even to those listening to me play, but they didn't quite measure up to the real thing (they were way cheaper). I haven't used any of their other pickups, so I'm no expert.
I hope that helps.
