2 tone pots 1 pickup

[fleabag]

Hope this doesnt sound too dumb, but i'll get over it.

Is it possible to have a 500k tone pot,  and a 250k tone pot , with a switch to select each tone pot when needed , wired to just one pickup ?

 

[ahpook]

Two pots, one pickup ? That reminds me of something....what was it now....

Anyhow, I don't see why you couldn't wire up something suitable - just need to split the usual connection between the volume and tone and wire in a switch there.

Thanks -  that'll do  nicely sir 

[fleabag]

Having said that, what value caps would you put on each tone pot, if any ?

And what  kohm Volume pot  ?

[Hellzero]

22nF and 47nF with 250KOhms pots. So the typical ones.

[fleabag]

Nothing on the 500k ?

[Hellzero]

You can put two 22nF for each of them (500 KOhms + 250 KOhms, ideally linear for tone).

[fleabag]

Ok - cheers H

Reading up about Linear v Audio ( Log ) the word was Audio for tone pots and Linear  for Volume pot, so would you say that's back to front.?

What i would like to avoid  is having the tone, and the volume , all happening at the last couple of millimetres of turning.

[Hellzero]

You hear in a logarithmic way, so the volume should be logarithmic. The tone for being usable all the way should be linear. Audio for a pot doesn't mean anything and beware of the letters A or B as they are quite often mismatched.

[ahpook]

Aaaaah, I see...you're after the TwoTone bass sound.

Thanks again H

Ap, you mean I'm much too young, when i could be having fun with pots ?

You knows it.

I’d go with a LPF on one pot and a HPF on the other, might be a bit more useful.

[fleabag]

Are they tone pots ?

It's more like a passive eq. Cut only, bass and treble. They did it on the ebmm USA passive subs and supposedly they sound pretty good. 

[fleabag]

Hmmm.... reckon i'll stick with regular pots. Thanks anyways

You could alternatively use one tone pot, and a rotary switch to select a range of different capacitors (certainly when Maplin was still in business they sold rotary switches that were very similar in dimension to full sized pots). This would function in a similar fashion to a tonestyler, but with much more fine control provided by the tone pot.

And G&L use the same methodology on the L series. At the end of the day in a passive bass you don't have a "tone" control as such. It is a Treble Cut, (or Bass cut in the EBMM/G&L scenario). So having 2 "tone" pots with different capacitors would just give you a different cut when fully on. When fully off the result is the same in either case.

Would a Stellartone Tone Styler do the job you are looking for but without the requirement for two pots and a switch?

Good points made chaps.

The rotary idea with different capacitors sounds like something i had on my MM clone a few years ago. It was called an inductor circuit, and you couldn't see the caps

I'll see if i can find an old photo

Still got it. Lobbed in a draw. Dont know if it still works

[Bridgehouse]

^ looks ok to me - give it a go

[fleabag]

The only trouble i can see with the inductor or tone styler is how you switch through to the setting you want and remembering.

Ok, it's not a biggie - but say i want position 4 and position 11  as my 2 tones, i gotta remember each time where my pot is currently sat, and either count forwards, or worse, backwards when changing tones

If i had 2 regular tone pots, they can be pre-set already, and just flip the selector switch

Do you have two specific tone settings in mind?

[fleabag]

Pretty much, yup.  But there's always that time when you want to twiddle just a gnats scrote, forward or back, depending
