I upgraded to this set of pickups from the stock Fender USA P-Bass Special pickups. Man, what a difference. I'm primarily a guitar player but I've had this bass for about 18 years for home use and occasional substitute bass work at a few churches when their normal guys cant make it. I always thought the stock pups were a bit weak, and thought about selling the bass to get an active rig. Well, don't think I need to do that now as this set certainly has given me the punch I've been looking for. The install was straightforward, but I did upgrade the pots and the bridge at the same time. The bonus Dunlop care kit worked nicely too.

First time using anything other than stock pick ups. I went with SD Quarter Pound PJ set for my Yamaha TRBX174EW bass. Perfect fit. Fattened my sound up nice, kept the brights and add some output volume. They let me play quicker and better because I don't have to work those strings as hard and that meant faster playing for me. Someone else said it, I will second it....keep the packing foam in the package or keep the foam risers from your old pick ups. At first mine felt ok but as the foam settled after install (2-3 weeks?) the pick ups felt loose. I took the foam from the packaging, cut strips to fit and added that to the foam already on the bottom of the pick ups, problem solved, nice firm fit. I recommend this step as well.

I bought this pickup set to replace the factory pickups in my Ibanez Mikro 4-string. Installation was not 100% smooth as I had trouble fitting the bridge pickup in the routed slot the factory pickup fit into. I don't know if this was differences in dimensions or tolerance between the factory pickup and the Seymour Duncan pickup.The sound was a noticeable upgrade, and a surprising benefit was that I immediately played live with greater confidence. The factory pickups had something going on harmonically that made me sometimes feel I was out of tune when I wasn't, and I would play more tentatively. This pickup set gives nothing but good, clean sound.

I am confused about this product. I have used Seymour Duncan pickups numerous times over the years with good outcomes. With this purchase, I was left a little uncertain about what I was getting for my money, as I will try to explain.I had purchased an inexpensive Ibanez bass. I am primarily a guitarist, but I like to dabble in the bass, so I didn't want to put a lot of money into it. One of my sons got into the instrument along the way, while I was out of the house when his mother and I split, and he left it unplayable after fussing in the wiring cavity. When I finally got my hands on it, I took it apart and found that the battery it used was not tied to active pickups, as I had presumed, but powered some sorry looking bass booster that I then found had terrible reviews online. I looked it over and saw that everything in it was pretty trashy, including that bass booster, the pickups, and even the pots, switch, and knobs, so I decided to tear it apart and do it all over.That's how I ended up purchasing this product. I wired up the bass, but unfortunately I've not yet had a chance to play it (not only was the wiring/electronics a mess on this thing, but the tuning machines were awful, so I am awaiting new tuners and cannot yet string it to try it out). I just didn't know that Ibanez had lines that went from excellent to just awful like this.The issue with the pickups is this for me. I expect Seymour Duncan to produce good products. I have never been aware of them having upper lines and lower lines of pickups (like what I just said about Ibanez; maybe they do, and I've just missed that, too). Here, again, with the bass not being my primary instrument, I bought the least expensive Seymour Duncans that fit the instrument.I am unsure why they were as much less expensive as they were. I mean, they're called the "Quarter Pound" Bass ... Set, and most of that weight will be brass wire windings, which make up the most expensive part of pickups, as far as I am aware, and typically are a significant part of what separates a good pickup from a bad one (the pickups that came out of the Ibanez feel like they weigh maybe a couple of ounces, and even the magnetic poles are little nothings compared to what comes on the Seymour Duncan pickups).So this is what's left me confused and a bit uncomfortable regarding this purchase, and I may be way over-reading things to get here, but I find myself wondering why these half-pound pickups, from this excellent brand, are so much less expensive than other pickups they make that would fit the same use (P-J style), and then they go and add instrument cleaning supplies and a cheap tuner free as enticements to buy. I just don't know what to make of it. I almost didn't want to buy the pickups because of the tiny, junk tuner that came with them. It's hard to complain about free, but why should Seymour Duncan be adding free junk to their expectantly excellent pickups? That scares me a little bit.Anyway, my tuning machines should arrive within a few days, and I'll be happy to get strings on the thing and check these pickups out. I hope to find that I am perfectly happy with them. Again, bass is not my primary instrument, and whatever they are, they have to be miles away better than the Ibanez pickups they've replaced.Not that it has anything to do with this product, but for what it's worth, getting rid of the cheapo-depot bass booster left me with an extra hole in the face of the instrument. I don't know why it didn't occur to me to just add a second tone pot and give each pickup its own tone control. Instead I got an idea to try something you never see on bases, and I am curious to see how it works out (I may just find out why it's never done!). I put a Gibson style 3-way switch in that extra hole, so I can choose from neck pickup or bridge pickup alone, or the two together. I suspect that may do more for tone color change than adding a second tone pot would have done, anyway, but I wonder if it's never done because the change is too dramatic or cutting one pickup out takes away too much of the power for a bass, unlike a guitar. Time will tell! At the worst, I'll leave the switch in the middle to use both pickups all the time, and it will just be an interesting way to have filled the hole that was left in the instrument.

Came as expected with a diagram guide to help you set it up.... the only thing is that the tuner can be rather tricky to use
