I had a big disappointment recently when I changed my Ibanez RG721 stock pickups with Sentient and Pegasus. At start it felt less dynamic, and the 2 pickups sounded almost the same. After I've checked in my DAW, the output is almost equivalent as my Strat Single coil and my other guitar with a Seymour Duncan TB6 is 10db louder (I've got -18db rms with the Pegasus/Strat Single coil and -8db with the TB6 when I pick with the same strength and same configuration - not exact science I know, but still it proves there's an issue). I think this diagram is the one that should be followed (but I may be wrong) : https://www.seymourduncan.com/wp-content/uploads/2015/05/2H_5WSPL_1V_1T.jpg And here is what I've got : What seems strange to me, is that red and white from both pickups are soldered at the exact same place, and I cannot find a diagram which may explain that. The guitar is definitely going back to the luthier, but I'm no expert, and I wanted your opinion about that before explaining myself to the guy And I wanted to give him some good arguments !
