Hello tb forumers! here is my question: what are the differences beetween model j & 9 j's? I can catch a pair on dp 123 at a good price, my actual setup is: 75 mij jazz, emg btc, bartolini 9 j pups. I'm mainly playing fingerstyle, and I'd like to get the monster tone for rock & reggae songs. do the 123's give a better bottom than the barts? do they reach the vintage vibe? I'm happy with the barts, but, at a good price why not take the chance to get a different flavour on the bass thanks a lot guys!
