While not being the smallest of finished items, it fits together nicely and can stack for as many decks as needed which makes true balanced operation a breeze.
This is a simple two deck "proof of concept" on proto boards with a 24 position switch that can have any desired taper you choose. They will wire up lust like a traditional pot with In, Out and Ground connections for each deck. I am so happy with the results I am planning another version on the 47 position switch that can have 1dB steps.
