Disabling Jazzmaster rhythm circuit. What do I snip?

Post by laterallateral »

Yeah, so I finally got fed up with replacing the tape I used to put over the rhythm circuit controls on my JM and am finally wanting to take the jump and just take it out of the equasion, altogether. I'm going to leave the hardware screwed to the pickguard for cosmetic reasons but I'm a bit at a loss as to what modifications I need to make to the wiring to do this.

Can anybody point this out for me on this here diagram?

TENKS GUYS.

Unsolder the blue and green wires from the rhythm pots, and solder them together, or just replace the two wires with one piece going from where blue comes out of the switch to where the green goes in. Doing this will mean it still works just as a neck pickup selector, rather than disabling it altogether. To disable it altogether, un- solder the green wire from the switch, and solder it straight to ground.


I hope this is right, otherwise I'm gonna look stoopid! Haha

The yellow wire needs to go straight to the tip of the jack from the centre lug of the volume pot - disconnect the white wire from the jack.

The hot (white or yellow, probably) from the neck pickup needs to replace the red wire on the 3-way.

All you need do is solder the white to the yellow on the left side and the white to the red on the other side, then desolder the top two (GRN/BLue) . You don't even need to tape the green and blue as they are now out of the circuit completely.Done!

Or even simpler, just desolder the left white and solder it to the yellow, then desolder the right white and solder it to the red. DOne!

Ok, so If understand correctly, this would be the simplest way to wire it without losing any of the functionality of the lead circuit and entirely bypassing the rhythm circuit, yes?

That is correct.....I mean essentially you just want to look at a generic schematic for two 2-conductor pickups wired to a 3 way toggle with one volume and one tone, which is exactly what you've illustrated.

you could also just unscrew the switch and push it down in the hole.

This is the simplest and quickest method.

plus then you don't even have the dead switch to hit your hand on. if you want to be sure it won't pop back out put a piece of paper or tape over the hole on the backside of the guard. also, that would be the easiest method to revert back to normal if you ever changed your mind or needed to sell it.

See the problem is I pulled a Mascis and jammed a pencil eraser down in the switch to keep it set on "Lead" and covered the entire controls with tape to keep everything in place. The pressure from the eraser must have fucked up the switch, over time. Now with the switch on 'lead' mode, I get half the volume out of my bridge pickup as I should. I messed around with the switch enough to STRONGLY suspect that it's not passing the bridge pickup signal right.

So I can either replace the switch but seeing as I don't use that feature at all, I might as well just bypass it entirely...

thouggh I do see the benefit of keeping the dead switch out of hand's reach. Perhaps a combination of deadness and out of rechedness(wtf?) is in order?

I don't want a gaping hole cause it looks shit and I'm superficial like that.

If you push the switch in, just remember to tape round the contacts on the switch so they don't touch any of your shielding or the roller bracket and short out the signal.
