Rickenbacker 620 wiring mod - help please.

[Brian T. Williams]

Hi,

I would like to modify my Rickenbacker 620/12, making the "fifth" knob a master volume control, rather than the factory spec "mixer" (tone balance) control.  The guitar has had no modifications to the wiring since new, so is, as it comes from the factory. The 620/12 has two (1 x Mono + 1 x "Ric-O-Sound" stereo) outputs; I only ever use the Mono.

As I am quite competent with small guitar adjustments and quite adept with a soldering iron, I am sure it is a job I could (and would like to) tackle myself, but I am unsure of the connections to make in order to modify, and the schematic wiring diagrams available from Ric are a bit of a mystery to me; (I am a player, not a technician)!

Would anyone be kind enough to help me with this simple (I am told) modification, possibly with a foolproof description and a simple to follow diagram (or photo).

Many Thanks..................Brian

Paul & Len....many many thanks for your help.

I have gone with Lens suggestion, following his directions and updated schematic and guess what.......It works a treat; just what I was looking for.

Paul I shall store for excellent diagram for future reference if that's okay.

Many thanks again........Brian.
