From the post
Another addition to Dan Armstrong library, The Purple Peaker treble booster. This layout is using two SPDT switches instead of the original setup. You could get closer to the original with using 2PDT, taking the ground to pins 2 & 5, Lo wire to pins 1 & 3, and finally Hi to pin 5 - leaving pin 4 unconnected. Personally i would still go with two individual switches... (Yup i know it's the same text i used for the Yellow Humper :))
