The strong point on mine is upper mids and wicked attack. With the Ampeg head set flat, cranking the treble wide open on the instrument itself turns this thing into a flamethrower that will cover up anything anyone else in the band can do! The lows on mine are OK, but not as “fat” or “warm” as a standard 2nd generation P-bass. Compared to the VINTAGE SCPB1's 8k and the HOT SCPB2's whopping 14k, the SCPB3 is more in the middle at 12k and it is an edgy compromise. While overwound mine does not sound boomy at all. Maybe you get an upper mid boost too from the larger pole pieces. This is without a doubt the best looking first generation P-bass pickup going at any price and very well made. I set up a '54 P-bass with one and it has been my number 1 player for 2 years. I also have a '51 reissue 2007 model with a custom wound split-coil pickup that is just slightly overwound, but it does not have anything close to the highs that the SD SCPB3 does. So the SCPB3 is a great value, especially if you want a versatile 51 reissue bass that isn't a one-trick-pony at a reasonable price. I don't get booming lows with this pickup and have to go to the custom wound pickup for that, but I do get a very wide range of usable tones and a very good up front tone for solos. This pickup will put the bass in the foreground! This is not a split coil design, so it is subject to RFI. A nearby TV or computer monitor will generate a ton of hum for it, so it isn’t the best studio bass pickup. If it was split coil wound it would be a truly exceptional pickup, but would also cost way more and probably wouldn’t sound the same. Even with the tone rolled completely off playing with a super-thick pick you still get a pick “clickey” sound so I always play this thing finger-style. I recommend the SCPB3 for gigging, but not for the studio…for finger players, but not pick players…and for players who want every note to be heard, but not for people who lack confidence or skill because any errors or faulty technique will come through loud and clear.

I got this for I bass I built to model after the 51' P-Bass sound. It has a fat warm tone with a funky feel. Highly Recommended!

After a friend destroyed the stock pup on my Fender P-bass '51 reissue, I took a chance on this as a replacement, and have not been disappointed. In fact it sounds way more solid that the original. I thought it might be muddy, like some overwound pups but the clarity is all there, with more balls. Excellent pickup.

One note: On a bass like this you can't slap without risking the low E string getting caught under the lip of the pickup cover. When that happens mid-slap, you make find your pickup ripped into pieces. Solution: don't slap or else slap carefully on a 61 P-bass.

Highly recommend the pickup.

I recently purchased an old Peavey bass that came with its stock 22 year old "super ferrite" pickups. It sounded ok at best, which I probably would have tolerated, except for the fact that it sounded horrible when I slapped. I knew I needed an upgrade so I did a little research and found out that these Bassline pickups are actually made by Seymour Duncan. These are specifically made for certain modern basses, and not a 22 year old forgotten Peavey relic, so I had to perform some modifications to get it to fit. However, when it was all said and done I was very happy with the end result. I'm now getting artifical harmonics with this new pickup without even trying. That's the first sign of a good pickup. Secondly, it makes my old bass sound like a more modern bass with a very full range of sounds that I wasn't capable of achieving before. It's absolutely worth the investment in this series of pickups if you're looking for an upgrade for your passive bass.

I put one of these in my kid's Squire Bronco Bass and suddenly it actually sounds like a bass. This is a great upgrade -- and if you have a low-end single coil bass with a plastic cover over the pup, you might find its actually a 6 pole guitar pup (surprise!) and here is your only alternative. Fortunetly it's worth it (by the way, its a Seymour Duncan).
