Hey guys im currently looking at doing some work on a 1987 warwick thumb i purchased. It has a after market custom paint job the stock pickups have been replaced with status graphite hyperactive pickups and though they sound good i want to get back to a more original style emg j pickups. Since this bass has been so heavily adjusted to im not hugely afraid of loosing resale value. I first plan on stripping the paint of it so i may refinish it. I also plan on reshaping and refitting the existing pickup holes back to j pickup size by adding back wood possibly walnut with bubinga veneer on top or straight bubinga. The bass has 5 control knobs and a coil tap switch and i wouldnt loose any sleep if I had to remove and fill in the holes left of two of the knobs and the switch, since i think the number of them look bad on the thumb body.My main question would be what preamp to get with the emgs? Ive looked some at aguilar as well as an emg preamp. Im looking for suggestions of what would be a good combination with emg active j pickups.
