I'm shopping for J style pickups replacements for my carvin, that has actually H50 stacked humbuckers pickups. I want some pickups with a lot of punch, without being too dark. I hesitate between 3 models i looked at: -the EMG J-set; -the Bartolini 59 J1 L1/LN1 Set; -and the Seymour Duncans Bassline AJB-5 active. Anyone tried one of these models and have a review about it? Which could be the best?
