Les Paul Jr.

[asdaven]

Has anybody wired a Les Paul Jr with Push-Pull pots like on an Esquire? Like one to bypass the tone control or both pots and the other to bypass the tone control and go through a small capacitor or resistor and capacitor to ground? For either a cocked wah or faux neck sound?

Thanks-

I've got a cheapo Epiphone LPJ with a push/pull, but it operates as a series/parallel switch for the humbucker, which I replaced with a GFS Filtertron clone. SO, nothing like what you want to do. But you proposal can certainly be done. It might be easier to have one P/P switch to switch the V pot in/out of the circuit, and the other to cut the tone pot in/out, and perhaps with a cap when "out". Both P/Ps up would be no pots, Vol up, tone down would be tone only, tone up, volume down would be vol only, and both down would activate both pots.

One would be a direct to output jack to pickup. And the other would be bypassed tone with a small set tone cap such as .0033 or .0022 to ground instead of the tone pot. Im thinking. Im getting the inspiration from a Esquire which offers these types of settings. On a Les Paul Jr. there is no switch so gotta use push pull pots.

Is it better to bypass both volume and tone or should I just bypass the tone? I got this same question for my Esquire. I feel the difference in output would be more worthwhile to bypass the volume pot too for more output but at the expense of potential brittleness. Now with the P90 on my Jr this maybe less of an issue. With a push pull I could just run the hot output jack wire through a push pull and then when down run it to the volume which is connected to the tone.

Bypassing the controls only achieves a tiny increase in overall volume compared with having them at maximum clockwise rotation. However it does allow you to quickly get there by switching rather than rotation and it does provide a brighter tone. If you choose to employ this and find the sound is too bright when bypassed, you can use a fixed resistor to provide some loading in the bypass position, to tame that down, slightly.

Does bypassing the tone control do anything? Versus bypassing both controls?

Changing this up.

Thinking about making the tone push pull a tone pot bypass with a bass cut RC circuit with a 0.56nf cap in parallel with a 330K resistor "in line" with the signal. This would be what I would call the "single coil setting"

The volume pot push pull would be a variation of the cocked wah mod or to just get a little more bass. Or basically shooting for a sortve faux neck setting. Here id wire a very small .0033uf cap to ground in parallel with the signal. This would bypass the tone pot too.

So how would I wire this up so when either of them are engage the tone pot is bypassed?

So one pot is going to be a cap to ground and the other is a in-line cap and resistor in parallel to cut bass.

Bypassing the tone cut circuit allows you to get a slightly brighter tone than having the tone cut circuit in place with the tone pot at maximum clockwise position. It also allows you to get this, regardless of the position of the tone pot. So you can easily and repeatably switch between a moderate cut in treble (pot somewhere in middle of the rotation) and the brighter tone just by flipping a switch.


Bypassing the tone cut circuit only requires one pole, not two poles (required to bypass the volume control or to bypass both controls).

The hot wire from your pickup will connect to both poles of the push-pull on the tone pot. We'll refer to this connection as point-p. One of the throws that are closed when the push-pull is in the 'normal' position will be wired to the input of the volume control. Your bass-cut network will be connected between point-p and this throw.

The other throw on this push-pull that is closed when the push-pull is in the 'normal' position will be wired to the tone-cut circuit. Both throws of this push-pull that are closed when the push-pull is in the other position will be unused.

---

The push-pull on your volume pot will have one of its poles connected to ground. The throw that is closed when the push-pull is in the 'normal' position, will connect to the end of your tone-cut circuit which is typically connected to ground. The other throw associated with this pole will connect to one end of the .0033uf cap. The other end of the .0033uf cap will connect to point-p.
