From looking at diagrams online, I think this is modern wiring, and I much prefer 50s. I thought I could take the capacitor and attach it to the middle lug of the volume pots, to the lower lug on the tone pots. However as you'll see, there's really not a lower lug, it's soldered to the tone pot housing on both. Can I use the top lug for the same effect? This is a 97 R8. I'm not sure what pots those are, does it make sense to upgrade those?
