How to CORRECTLY install bass pickups


PeeJayEU

Recommended Posts

hey guys,

 

 

several months ago, i purchased some basslines pickups and installed them (along with a new finish, bridge, etc.). the bass plays fine, but i'm sure the pickups aren't installed correctly. They are flat with the pickguard. They aren't raised towards the strings and don't spring if they are pressed. I know i did something wrong even though they work. i imagine fixing this would help the bass sound better. any advice? do i need to be clearer?

Actually, go here ;)http://www.stewmac.com/shop/Electronics,_pickups/Pickups:_Parts/Humbucker_Pickup_Height_Springs.html

 

They have pickup height springs, and they're very cheap.

 

You simply put a spring on each of the screws before you install it into the bass. I prefer springs to the foam, I feel you can get a finer, more consistent adjustment with them.

 

Once installed, you should set the pickup height correctly on your bass. Depending on your bass this height will differ, but on my Corvette with Jazz style pickups I have the pickup height set at 5/32" from the top of the pickup to the bottom of the string for the neck pickup, and 4/32" for the bridge pickup.

 

The pickup height is quite important.

 

Too low, and you'll have low output from your pickups, too high, and the magnetic field of the pickups will affect sustain and intonation.

 

There is a sweet spot where you'll get good output, and a nice full rich tone without affecting sustain.

 

Good luck.

 

:D

Yeah, the foam under my pickups is something I cut out of something that was never intended to go under a pickup. That's because the original foam compressed & no longer pushed the pickups up very much when I turned the screws out. So look around for something that isn't too dense--it has to give when you screw the pickups down--but not to flimsy, either. My Music Man has a spring-loaded pickup, and that works MUCH better. Oh well.

I've gone back and forth between springs and foam over the years and have settled on heavy duty black rubber automobile weather-stripping foam. It's the really heavy stuff that takes about 25 years to break down. It took me a long time to find the right stuff that stays springy and never gets compressed. It's not cheap. I find that the springs are a pain to keep in place while you are putting the pickup in and they are too easy to loose.

You may also buy the door weatherstrip for homes at Home Depot or Lowes. There are many different sizes. I think 3/4" is the one I use. I prefer the spings but they can be a real hassle to get in place. The Fender strat uses medical tubing. I have never used it on a base but it should work just fine.

I am having this same problem at the moment on my jazz bass. It is bearable for now in that I have found a good placement, but I know I'll need to "refoam" soon.

 

That Fender brand weatherstrip (in the link 09 posted) is interesting, hilarious, and expensive.

I think I'll go to the hardware store...

 

Peace,

I'm a lot more like I am now than I was when I got here.
