Seymour Duncan SPB-3

This was my first pick up replacement. I replaced the stock pickup in my old Warwick PJ with the SPB-3.
Seymour Duncan includes a manual with the electronic schematics for this pickup, which made the installation a lot easier. These pickups are meant to be a drop in replacement for any Fender P or PJ bass. In my case, the replacement wasn't exactly 'drop in', as Warwick uses other dimensions, materials, and designs than Fender. Especially their use of a spring instead of foam underneath the pickup made this a little bit challenging.

The sound however, makes this all worthwile. The output is almost at twice the level as my stock (MEC) pickup. It's very ballsy, very low end articulated, fatty, and maybe a bit under represented in the mids. As the wood in my bass make for a particularly mid heavy sound, this works out well, but it is something to be noted. All in all, do recommend!

The only bass pickup I will use.

I'll admit I first learnt of the Duncan 1/4 pounder from Mark Hoppus when I was 14 and got my first bass, it took me several years as a lefty to get a bass with a P pickup rout and the first thing I did was pull out the stock pickup and put one in.

Now as a much older and much more 'cultured' musically person I will only play P basses and they have to have these pickups, I even yanked the lovely Custom Shop Pickup out of my USA P bass and put one in.

Yes they do in your face rock and punk but they have a subtle tone that many people overlook as well. You need to get used to turning your amp down a little when you first get them, they cut through much more than any vintage voiced P pickup and as such you need less volume, when running them in a rig with a boost channel you find that extra output pushes them way above any normal P pickup, not just louder but retaining all the bass and oomph that you want from your instrument.

I have 4 P basses all with these pickups, I have tried dozens of different pickups and nothing even comes close.

I bought these pickups to replace the stock Fender ones on my Mex P-Bass. They provide much more bass whilst remaining tight and not too muddy. Playing on your own, they don't sound overly impressive but it's within a mix where these really shine as the bass cuts incredibly well and really provides a lot of thump. I wouldn't really recommend these for much more than rock/metal however as they could be a bit too 'strong' for other playing styles (I am using them for rock music).

I am also surprised to find they react really well with my Big Muff considering the amount of low end they put out.
