Active to Passive Electronics

Discussion in 'Hardware, Setup & Repair [BG]' started by PCDoc12, Oct 21, 2004.

  1. Has anyone had their electronics converted from strictly active to active/passive? This would be advantageous in case of a battery demise.

    There is really no way to convert the electronics themselves. If the PUs themselves are active (for example: EMG and some Duncans) they can not be made to function without battery power as they use the current in creating the magnetic field.

    If you are using an active pre/passive PU setup (as in Bart PUs with an active preamp) it is possible. You just need a DPDT on-on push-pull pot or switch, the right diagram and the ability to solder.

    Depending on the design of the active preamp, it may not be possible to have any tone control at all in passive mode without seriously changing the circuit and it's components, but if you are thinking of it in terms of emergencies, it'd certainly do.
  3. Thanks, my friend. I appreciate the advice.
