I just put some TV Jones Filtertrons in my '67 Gretsch Double Anniversary and wow!!!! It completely transformed the guitar into something sublime! Those Hilotrons that were on there were kinda cool in a unique way, but holy crap these pickups make the guitar sound like the Gretsch I have always wanted. I have owned a few Japanese Reissue Gretsches nad kept selling them because they weren't exactly right. Standard Filtertrons are a little brittle on the top end but these are not at all. At high volumes I could never even use the neck pickup on the Japanese Gretches that I had in the past, it got too muddy and just was a feed-back hell. But with the TV Jones the neck still cuts through. I was really on the fence with this purchase because they are so pricey... $250 for a set. But they are well worth the money. Btw... I am not affiliated with TV Jones at all. Just excited when you find something good!
