I recently performed a complete electronics surgery on a Mexican J Bass; opting instead for EMG pickups and electronics. Looking at the pic with the new chrome knobs (from L-R)…

1. Mid cut/boost with sweepable freq.
2. Stacked High & Low cut/boost
3. Neck pickup volume
4. Bridge pickup volume

The previous incarnation sported an active/passive toggle switch; and now the new version has removed that toggle switch and left a hole in the plate (I might bring the switch back). I absolutely love the sound and tone control I am getting from this particular set (EMG “J5 Set”) although, for the unacquainted, it is worth mentioning that these particular EMG’s will take you even farther away, from a “jazz bass” sound, than the previous Fender Noiseless pickup set already had. sg
