    Hello everyone. On my Ibanez BTB, I have three knobs. First one for volume, the third one for bass/treble.

    What is the middle one for? I never figured it out.

    I'd be willing to bet it's a pickup pan knob... if I'm right, it can either evenly blend both pickups, or shift the emphasis from one to the other.

    Hmm, and what does that mean exactly?
     
  4. I imagine it's actually a midrange eq knob, affecting the volume level of frequencies between treble & bass. If it's a pan knob, turning it all the way in one direction will give you signal from one pickup, the other direction, the other pickup.

    Correct, the knob you're talking about is a pickup pan, with a detent in the center.
     
  8. Yep, Its a pan knob.

    As far as I know, there are no preamps that have only three knobs and have a V/M/B-T stack set up. So I guess you have the BTB 300, right?


    And to Unchain

    BTB's only come with 2 pickups, both dual coil.

    Thanks. If it has 2 pups, I knew it was a pan, but one it could be a midrange. Thanks for the correction, Tbird. :smug:

    Maybe I can offer a better explanation. Without that knob, your bass would automatically balance your output between both pickups. Said differently, each pickup contributes equally to your sound (although based on your technique and hand position, one pickup may end up affecting the sound more, though both are working equally hard at it). Now, insert a pickup pan knob (also called a blend knob), and as you turn it to one extreme or the other, the balance between the output of each pickup shifts. Typically, turning it clockwise causes the neck pickup to carry more of the load in creating your sound, and conversely, counter-clockwise puts more responsibility on your bridge pickup. Since each pickup affects your sound differently, you get different resultant tones. It's virtually the same thing as using a fader in your car stereo and shifting the balance from the back seat to the front seat, except with multiple pickups in a bass, the overall tone changes. Make any more sense this way? :)

    Yeah, I get it now. And TECHNICALLY, I have 4 knobs, only my last knob is a two story knob, with bass on the bottom, and treble ontop.
