So today my SX short scale jazz arrived, I was impressed for a hundred bucks but was overall underwhelmed by the pickups (I bought it expecting to upgrade the pups anyways). The pickups are sort of hollow sounding. is the only way to describe it, and the 60 cycle hum is worse than anything I've experienced. However, the bass is a nice short scale platform so I am looking for some quality humbucking Js (non stacked) that have a good overall tone; meaning not to focused on mids, highs, or lows, but rather having good tonal flexibility and high output. I have heard good things about Lace Sensors and DiMarzios. While I'm on a rant, would it be a good idea to replace the cheap pots and output, or do SX owners find them to be adequate?
