Push/Pull pot for volume AND tone

[dgorjup]

Hey guys,

I'm building a new guitar and i would like just one pot to control both volume and tone. The only way i can think to do this is with a push pull pot but i cant get my head around the wiring.

Is it possible? and if so can anyone help with a diagram?

cheers

forget push/pull, it won't work. dual concentric pot is the way to go.

or if you really mean to control volume and tone with one pot together (lower volume means also more/less highs) then you'll need a balance pot.

concentric pot's would do the job but they look abit odd for me...

the other option i would go for is to just have one pot that just controls volume and not have a tone pot at all.

is that possible?

I imagine it would be possible to wire a push-pull so that it was a volume when down, and a tone pot when up.

However, this would mean that when it was set to volume, the guitar would have no tone control, and vice versa - not the most useful arrangement IMHO.

You can go for no tone pot, no problem, just get a good set of pliars and pull it off.
Or remove the pot and short the wires gpoing to it. Use an old piece of gum to fill up the hole in the guitar top where the shaft came up. Sorted.

Would the tone/volume level set stay the same when you changed the pot to pull/push?

eg: pull, set tone to 10, push to engage volume (tone stays at 10) volume is adjustable

by shorting the wires, do you mean connecting + and - and taping off?

No - DPDT switches (like those in push-pull pots) are either/or switches. Set to tone, and the volume will be full, with no control; set to volume, the tone control will be set to full (ie: no treble cut).

What isn't possible is to set the volume (for example) halfway, and then use the tone control to cut the treble, keeping the halfway volume setting.

Go with separate pots, or a dual-concentric, I'm afraid.


I'm getting an idea that it might be possible to have a number of discrete volume/tone settings on a 5-way rotary switch, but I have a lecture in about 10 minutes and I'm away for the weekend.

Something like:

1) Full volume, full treble
2) 1/2 volume, full treble
3) Full volume, 1/2 treble
4) 1/2 volume, 1/2 treble
5) Off switch

But I haven't used anything like that, so I'm going to leave that hanging for someone more experienced to respond to...

Just mount a two-axis analog joystick on the geetar! ;D

Thanks for clearing that up!

I think im going to just remove the tone pot and stick with one volume pot. Does anyone have a diagram? theres a topic here guitarnuts2.proboards45.com/index.cgi?action=display&board=wiring&thread=1158241775&page=1
But i dont understand those kinds of diagrams =[

Cheers for the help!

Would this be the best way to do it?

Altho i would like 2 Humbuckers in my new guitar, so would i just add the wires from both pickups to the one pot as shown in that diagram?

ew..............who do you think you are? MacGyver or sumthin'?

ya know, they do make plastic hole covers.

Like this...



Apparantly it's a Ztar. The picture came from here, although these are cooler!
