No. Uniting the tonal characteristics of this two basses the pure way - a full passive JB™ and an active humbucking MM™ - requires a single coil pickup wiring for the neck pickup and the "Jay"-part of the hybrid pickup, so that hum is a naturally result of this design in some settings. In the humbucking mode – we call it the "Ray" mode – you´re able to combine the hybrid pickup with the neck pickup, too. This is an additional feature. But take note, that use of the neckside single coil pickup in may cause hum, if driven with the active electronis. To achive an authentic "Ray" sound, you should turn the balance knob fully backwards - and so your bass is hum-free and dead quiet now.
