When I first added a third pickup to my 360/12 and wired it in using the standard method, I was thoroughly unimpressed. I didn't feel like it was really adding much to the sound or any kind of real tone options, so I started playing with variations to see whether I could actually get it to do more. I drilled a new hole in the pickguard, right in the middle of the four V&T knobs. Then I installed a 3-way mini-toggle switch in the hole that would mix the middle pickup in with either the neck pickup (standard system), the bridge pickup or turn it off. It gave a bit more tone variation, but I still wasn't thrilled, even after mixing a Ric-O-Sound box into the works. I seriously thought about the Fender-style blade switch, but I've been using stereo-wired basses for 35 years and decided to go that route instead and really like it. I later added a mid pickup to my 330/12, so that I could do the same thing and am quite happy with it. On a mono guitar, like the 330, 325. or 350 it works like this. A volume pot is added in the new sixth hole in the pickguard and the mono output jack is replaced with a stereo jack. The neck and bridge pickups are wired just like any two-pickup Rickenbacker with the volume and tone controls and fifth knob. Their output is run to the stereo jack's "tip" position. The middle pickup is wired all by itself to the new volume pot and then to the stereo-sleve portion of the output jack. There is no tone control, but it doesn't need one - it's like having the tone knob all the way up. It's ground is wired to the same loop of ground wiring that the neck and bridge pickups share. Plug in a mono cord and you have standard two-pickup Rickenbacker sound (which from my experience is almost the same thing as standard three-pickup Rickenbacker sound). Plug in a stereo cable, which goes either to a splitter box or which splits into a Y-cable on the amp end and you suddenly have some serious tone options. You can run each cord to a different amp or amp channel and through a completely different set of tone controls or effects. I usually run neck/bridge combo through any effects used and the middle pickup clean and unadulterated and then mix it in with the volume pot as desired. Same for recording - two tracks, one of them unaltered clean sound from the middle pickup. It's not for everyone and no doubt, horrifies the purists, but there is no debate about the wider range of tone possibilities that it offers.
