'I'm looking for something similar from BKP but maybe with a more character because for me 498/490 combo lacks something (aggressiveness?).'
My Gibson Firebird Studio came with the 498/490 combo. I tried to work with them but they are not good. Tim recommended the RY set and he was spot on. The 498 went from shrill at low volume to mud at high volume. Crank the RY bridge and it snarls and bites - the sound of classic rock but it'll do a lot more. I'd given up on neck HBs until I got the RYs - now I play a lot of solos on the neck. RYs take a LOT of dialling in. Very sensitive to height adjustment.
