Owners of Carvin LB75P, do you have manual explaining controls

Discussion in 'Basses [BG]' started by BluesMan845, Nov 22, 2010.

  1. I have a Carvin LB75p which has been sitting here for a long time not getting any love. It belongs to my brother who has been living out of the country and I have always meant to pick it up and play it but my LB70 always get the love.

    Anywho, I started playing it this weekend and I'm wondering about the controls on the bass. I am pretty sure that the switch operates the passive/active mode but I'm unsure. The 3 larger knobs are a little confusing. The top one is the overall volume output and I assume the middle one operates the same as my LB70, dialing in the blend between pickups. The 3rd one has me a little puzzled though because it also has a middle point but I'm unsure what it is meant to balance. Possibly the control for the piezo P/U's?

    I can't find the manual on Carvins website for this bass and it's version of the electronics. Does anyone have a link to them, or have a digital copy you could send me?

    The third knob is a blend between the magnetic and piezo pickups. There's a diagram at http://www.carvinguitars.com/customshop/bassfeatures.php -- the EQ controls on the new ones are slightly different with the stacked knobs to add sweepable mids, but the pickup controls are the same.

    If you have 6 knobs and a switch, it's the previous generation preamp from the one on the website. As mikezimmerman said, the top controls function the same.

    I have the same 6 knob version on my lb76p. The three large knobs are: vol (pull up for passive), magnetic neck/bridge blend, magnetic pu/piezo pu blend (rotated towards the neck is mag only, towards the bridge is piezo only, anywhere in between is a mix)

    The small knobs are bass, mid and treble. The switch is usually a coil split for the bridge humbucker.
  4. Thanks for the information guys. I didn't realize the volume knob could be pulled up. Looking forward to picking the bass up in the morning now and experimenting.
