I'm looking into how to wire up a 3 pickup bass, with the bridge and neck having Delano SBC HE/S-4 Quad Coil Series Soapbar set and the middle pickup is a Delano JSBC HE Split Coil Series Skinny Soapbar. How would I best get each pair selectable with also having all three on one selection and each on their own if possible? I'd also like to be able to blend them in pairs onto a master volume, thinking 300k pots would be best here but I'm all up for suggestions to try. I'm not afraid to wire anything up, not too difficult to figure out usually. Thanks for the in advance advice, I'm probably crazy tho
