I'm planning on ordering a MIA Jazz, but also have the hopes of installing a Sadowsky Preamp. now normally this wouldn't seem like a problem to me, until i realized that the S-1 switching shares the same pot as the Active/Passive pull switch on the Onboard Preamp. now my question is could the active/passive switch be put on a seperate volume pot as to the s-1 switching, or would the s-1 have to go? also, would it be required to cut out a chunk of the bass to make space for all the electronics as in the Marcus Miller sig? or is that just for decoration?
