Middle Pickup Rewiring Notes:

The section of the Technical Pages provides information regarding the rewiring of the middle pickup of 325 and 350 model Rickenbacker guitars. By way of introduction Chris Bishop writes "What you end up with is a regular acting 2 pickup rick, less 5th knob, and the fifth knob acts as a volume for the middle pickup. The mid pickup functions independently of the switch, and it does not utilize a tone knob. Works great on my 350, but takes a little getting used to. To utilize the mid pickup by itself, you'd have to kill the volume on the other 2 pickups. Before you begin, please be advised that this modification will void your Rickenbacker warranty.

"To perform this, have the headstock facing away from you. Remove the pickguard and flip it over:

1. Disconnect the middle pickup lead from the top right post on the selector switch. Also, remove the mid pickup ground (braided wire) from the bass tone control, or whichever pot it is soldered to.

2. Find the red wire running from the left post of the 5th knob to the center post of the bass volume pot and remove this wire completely. Keep the wire as you'll need it later.

3. Find the red wire running from the bottom right post of the selector switch to the middle post on the 5th volume pot. Remove wire at middle post of 5th knob, and solder it to middle post of bass volume pot.

4. Solder the mid pickup lead to the center tap on the 5th pot.

5. Solder the mid pickup ground (braided wire) to the left tap on the 5th pot, as well as to the pot itself. You may have to strip the wire to have enough braid for this. I ran the braid through the tap, soldered it at the tap and then to the pot.

6. Utilizing the wire removed in step 2, run it from the right tap of the 5th pot to the left tap of the bass volume pot. Tracing this wire, you'll see that it is the hot supply from the input jack, which is jumped through the treble volume pot as well."
