On/Off for preamp

Discussion in 'Pickups & Electronics [BG]' started by i_got_a_mohawk, Jul 27, 2005.


  1. I may be getting a passive bass in the near future, and i'd want to put an active pre amp in it, but, what i also want to do is have it so it can switch between the active or passive pre, i have a rough idea of what to do, i think

    Switched to passive:
    pickups -> pickup selector -> volume -> on/on switch -> tone -> Output

    Switched to active:
    pickups -> pickup selector -> volume -> on/on switch -> active pre -> Output

    would that be the right place to have the switch ?

    why not keep the tone control in the circuit either way?
    I've played active basses, such as Sadowskys, where a tone control is useful in active mode. The Sadowsky preamp is boost only, so on a bright bass the tone control is the only way to tame the highs.
    Also in general, a tone control has a different sound than cutting treble on a preamp.
     
  3. so stick the switch in after the tone control, and just have the active pre in parallel with a blank (so to speak) wire? , and connecting 2 sets of wires from different sources to the output jack is ok aye ?

    ....or skip the mods and buy a Sadowsky preamp pedal with an on/off switch as well as a mute switch.
     
  6. I have a sansamp pre pedal

    I just want a bass with active and passive controls on it, not another pedal
