I did it and it not only fits perfectly and improves the visual presentation of the bass, it also adds a 4-band EQ to rival the sonic qualities of a Bongo!!
I replaced my SUB 4 pickguard with a SR4 pickguard pickguard and its fits perfectly. Make sure you order your Pickguard from EE customer service. I originally purchased an after-market pickguard and the quality was awful. Hope this help ya!
