  • Jazzmaster upper volume control problem. Please help! : (

    I got some new CTS mini pots for my MIJ jazzmaster. I'm wired everything according to the Seymour Duncan Wiring diagram linked below. I haven't put the strings on the guitar yet but I'm just resting a string over the pickups to make sure everything is working - I also put some new pickups in the guitar. When using the upper controls, the tone pot works - I can hear the highs rolling off but the volume doesn't work. It almost sounds like another tone control...

    Anyone know what this could be? I got the pots from Guitar Resource - page link below as well.

    The diagram calls for two linear pots but the tone is an audio - what I got from the website, should this be a problem? - The tone is working, but not the volume. The volume is 1M Linear as the diagram calls for.

    Thanks

          Wait - What?

          I've had the same problem with the rhythm circuit volume for a while now. It sounds like a second tone pot - as I roll through it darkens then brightens up again. I actually kind of like how it sounds so I've never fixed it, but if it's just a grounding prob I'll get in there --


          Was that your problem? If so, was exactly was the fix again?

          When my prob first made itself known, I posted elsewhere and was told basically just to upgrade to a new pot. If it's just a soldering solution, then I'm there...

            Hi,

            Solder a wire from the cap on the volume pot to ground.

              Hi,
              Newbie Here so greetings to all.

              I have a question on this topic- I've rewired a CIJ Jazzmaster with new pups and upgraded the hardware, following this diagram: http://www.guitar-mod.com/wiring/jazzmaster_stock725.jpg

              However, either I've made a boo-boo or the diagram is wrong....
              The 'top plate' controls work fine, but with the selector switch 'down' (ie. lower controls should be working) the Volume pot is acting as a tone control (1=Dull, 10=Trebly) and the tone control is doing nothing at all....
              Any ideas?
              cheers
              nick

                I'm late but I knew that was the problem as soon as i read your post cause if you dont ground lug 3 on volume pots it works kinda like a tone control, never going completely quiet. When you turn the vol down you are sending all signal to ground and that's why it cuts out.

                  ^^^Possibly. The upper volume, however, doesn't do much. It basically goes from zero to about 5 and it sounds more like a tone control throughout the range. If yours mutes the pickup when it's turned down all the way, it's probably working properly.

                    Man, you just saved my arse. And I'm not even British. I've been tasked with repairing a '64 Jazzmaster that was rewired by either Franz Kafka or Edgar Allen Poe.

                    I gutted the bad wiring and re-wired the guitar exactly to the Fender specs and the Seymour Duncan diagram (and cross-referenced it against numerous other diagrams when the rhythm circuit controls wouldn't work) . None of the diagrams showed the ground wire from the rhythm volume lug to ground. Not a single one. The rhythm circuit controls will not work without this ground. How could they ALL get it wrong?

                    I owe you a gigantic beer.
