    Will the Sadowsky VTC pot work with any preamp?

    I'd imagine that it would, seeing as how the Sadowsky preamp works like any other preamp... passive signal in, active signal out...

    The Vintage Tone Control is a passive tone that is found on any passive bass.

    I've used a passive tone control on Aguilar preamps, EMG preamps and a couple of others that slipped my mind.

    Is the VTC on a Sadowsky a different value of potentiometer to jive with the active electronics, or do they just use a 250 or 500k ohm pot? I'd love to add one to my Sadowsky outboard pre and just leave the controls off the bass!

    Sadowsky VTC is not a single pot. It's a kit:
    * A 250k push-pull pot: It's used as a passive tone control and a switch (usually set as active/passive but you can use it in any way you like)
    * A stacked 25k/25k pot: This is used to boost bass/treble on active circuits requiring 25k pots.
    * 2xcaps: One for passive tone control, the other for silent switching between active/passive

    This kit is designed specifically for onboard Sadowsky preamp which initially came without passive tone control. It can also be used with Aguilar OBP-1. The idea is to add a passive tone control without drilling another hole on your bass. It's not meant to be used with outboard pre, or any onboard pre other that the two above.

    Well, essentially you ARE telling me that the VTC (Vintage Tone Control) is just a 250K pot and a capacitor, everything else in the "kit" is simply there to accomodate switching an always active bass to an active/passive bass without adding an extra hole to the bass...Because it is just a 250K pot and capacitor, it can either be in the bass directly after the pickups, or in the outboard preamp box before the active controls.

    Thanks for the info,

    Yes, 250K, 47nF tone control.
  8. does anybody knows the value of the "switching" capacitor on VTC?
