Hey everyone, I recently ordered this bass: http://www.rondomusic.net/sjb62qmdfretless.html In the description, it says that the pickup measurements are 3 5/8" x 3/4" Now I am obviously going to exchange the pickups, but I'm not sure with what. I found some barts that I would like to put in to them, and I've narrowed it down to these choices. http://guitarelectronics.zoovy.com/product/59J1LS The only problem with these are that they are for a 5 string bass, is that a problem? Also, they are .01 inches too tall, and the bridge pup is 1/16th of an inch too long. Is that going to be a problem, or will I be able to squeeze them in, if they ever work, considering that they are for a 5er. The other option: http://guitarelectronics.zoovy.com/product/9JL1LN1 The only thing with these are that they are 1/8th too short (length), and .02 inches too short (height). I would get these, but I dont want a gap in my pup spot. So you think these will make a noticible gap? Also, is it likely that I'll need to get a preamp with all of this? Or will I be able to use the one that came with it. Finally, if you have any other recommendation, feel free to post them.
