2 tone pots 1 pickup

Recommended Posts

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 ?

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.

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

And what  kohm Volume pot  ?

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

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.

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.

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.

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

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?

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