Spring Reverb pre/post eq switch

I built a capacitor-based passive eq that I'd like to be able to switch between the input transducer and output transducer of a spring reverb.

Will I need a 3pdt switch for this, or can it be done with a dpdt?

draw a circuit of your idea so that the forum might understand better your intention e money. sounds unworkable to me at this stage tho.

the impedances of the drive and pickup sides of the tank (if thats what u mean) are so different as to require entirely different eq solutions.

the best place to eq the drive side would be before the power stage that drives the spring. and the best place to eq the picked up verb signal would be after the initial pick up amp.

hope this is helpful
