The two identical pots would be wired in parallel, not an L-pad.
So you have two wipers carrying the signal but now you have to consider the
paralleled resistance and pick the pots accordingly.

I was describing an Lpad. A pot (or parallel pots) cannot present a reasonably constant impedance to upstream components whereas an Lpad pretty much does. As a result, my inclination is to either construct a fixed Lpad out of two appropriate value resistors OR find a quality multi pole/multi position switch and construct a stepped Lpad (vs common continuously variable type made of two way different value rheostats .
A fixed resistive L Pad will avoid switch contacts, which is a good thing . Employ well chosen 10 Watt Rs.
