Pros - A DEAD QUIET, killer sounding, Hi- fidelity Precision bass replacement pickup that leaves me wanting for nothing any of my passive bass pickups have.
Cons - If you decide that you want to try this pickup- You will need to ROUT a battery space in vintage basses- DON'T DO THAT... in later basses with a 'Mexican style' continuous rout from the pickup cavity, you probably wont need to do that. Mine is a 2006 Japanese made Fender, and it's lefty. So, I'm never selling it. No one will know I routed it until I'm long gone.
I do NOT like having to unplug the jack in between sets, and after I'm using it. But, I'm kinda used to that with my main fives.
Wow... what to say... I have one of my own custom made five strings equipped with two EMG 40 J's, the full BQS system, a PA-2 preamp booster, and 18v power.
There is absolutely NO shielding whatsoever in the cavities, and it's the quietest bass I own!
I really wanted to try an EMG P-bass pickup in one of my basses. Even though I have been moving away from active pickups in my new builds... This experiment has amazed me. The output of this pickup is beyond strong. I had a bit of trouble dialing it in on a gig switching to a passive jazz bass! The fidelity and extended upper frequency response of it actually makes the treble cut tone control usable! I like it so much, I bought another one!
