Why is my B String quieter than the other strings?

    There is a volume drop in my B string. All the others sound even.

    With the balance rolled all the way to the neck pickup it's more noticable, but with the balance rolled all the way to the bridge pickup, it's almost even w/ the other strings.

    I checked the string height above the neck pup, and the B is actually a tiny bit closer to the pup, then the E is.

    The bass is...
    Warmoth Gecko
    Bubinga Body
    Wenge Neck & Fingerboard
    Seymour Duncan Active Jazz Pickups and Tone Circuit
    Kahler Bridge

    Problem is the same regardless of amp setup.

    Strings are only about 3 weeks old.

    Any ideas what else I should check?

    Maybe its a dead string or the string is too close to the pup?

    Could be related to the EQ settings you are using as well...

  3. Good call. The string could be a dud. Also, if the string is too close to the pickup, the magnetic force of the pickup could suck the life from the B string vibration.

    This is a duplicate post to one on another forum, so I'll respond here as well...

    Try swapping your B and E strings, so it's tuned EBADG, and see if the effect is still there. It's possible the large excursion (movement) of the b string is moving outside the sensing area of the pickup a bit. This would be consistent with it being worse on the neck pickup.

    What pickup models are they, specifically?

    :edit: And which Gecko 5 model is this, Small, Medium, or Wide?
  5. Sounds to me like the speakers you've played your bass through won't handle the low B very efficiently. A lot of them don't. Try equalising at your amp to boost around 31 htz.
  6. I had the same problem with my Steinberger XP-4, only it was the G string. It also had Seymour Duncans, if I recall.
    The problem was the pickup – when I removed the pickup flipped it 180, the E string became the weak one. I noticed that when I touched a screwdriver to the pick up, the magnetism was stronger on one side than the other.

    Try to make the distance string/pickup a little higher. The string can vibrate better now and the volume loss can be a lot less, although it sounds contradicitively, it can work out very well.

    Thanks everyone for the helpful responses...

    Gecko Small w/ Basslines AJB-5 pickups. I have the kahler bridge set with pretty tight spacing, I don't think the string is going outside the sensing area of the pickup. I think {OE} was right about the pup being too close to the string. As I lowered the pup, it started to improve (unfortunately, the cheap screws provided by SD stripped before I got the pups where I wanted them). Can't seem to find replacements anywhere, either! :mad:

    The Bassmaniac,
    As it says in my first post, problem is the same regardless of setup. I've played the bass straight into headphones, straight into a DI box into the house PA at a gig, and a few different amps/stacks.

    I tried testing the magnetism with a screwdriver and it seemed even across the pickup. If the problem isn't 100% fixed once I get replacement screws to lower the pups a little more, this may be something I should look into further. Thanks!
