I'm wiring up a bass, two pickups, one volume, one tone, and a three way toggle switch. Should I solder the cap to the back of the tone pot like in this diagram? Or can I connect one leg of the cap to the tone pot, and the other leg to the volume? There would be no need to use a separate wire to connect from the volume to the tone. Kind of like in a typical LP/SG type wiring. Are there any differences in sound or functionality in one vs the other?
