Hi, I have an american standard jazz bass with s-1 switch. I love my jazz bass, it is the only bass so far that I've felt somewhat content with but I feel the pickups are lacking a bit. I was thinking about putting in a set of lindy fralin or norstrand nj4 js into my bass but upon speculation came across a question I could not find an answer to myself. So I turn to you tech-heads in the electronics/pickup forum. My question is this; with the above upgraded pickups can these still be compatible with the s-1 switch? this question only concerns me because while some have mixed feelings about the s-1 switch, I simply love the idea and love the additional versatility this button brings to my tone. You get that lovely classic jazz bass tone with the switch off and with the switch on it just beefs up the tone and sounds incredible for slapping. Also anyone who can make a fair judgment between the two desired pickups please post your opinions, I would love to hear them. Thanks guys! Talkbass is one of the most insightful places for bassists and I love it here!
