fleabag Posted November 13, 2018 Share Posted November 13, 2018 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 Posted November 13, 2018 Share Posted November 13, 2018 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. 1 Quote Link to comment Share on other sites More sharing options...

fleabag Posted November 13, 2018 Author Share Posted November 13, 2018 Having said that, what value caps would you put on each tone pot, if any ? And what kohm Volume pot ? Quote Link to comment Share on other sites More sharing options...
Hellzero Posted November 13, 2018 Share Posted November 13, 2018 22nF and 47nF with 250KOhms pots. So the typical ones. Quote Link to comment Share on other sites More sharing options...
fleabag Posted November 13, 2018 Author Share Posted November 13, 2018 Nothing on the 500k ? Quote Link to comment Share on other sites More sharing options...
Hellzero Posted November 13, 2018 Share Posted November 13, 2018 You can put two 22nF for each of them (500 KOhms + 250 KOhms, ideally linear for tone). Quote Link to comment Share on other sites More sharing options...
fleabag Posted November 13, 2018 Author Share Posted November 13, 2018 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. Quote Link to comment Share on other sites More sharing options...
Hellzero Posted November 13, 2018 Share Posted November 13, 2018 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. 1 Quote Link to comment Share on other sites More sharing options...

paul_5 Posted November 14, 2018 Share Posted November 14, 2018 I’d go with a LPF on one pot and a HPF on the other, might be a bit more useful. 1 Quote Link to comment Share on other sites More sharing options...

They did it on the ebmm USA passive subs and supposedly they sound pretty good. Quote Link to comment Share on other sites More sharing options...
fleabag Posted November 14, 2018 Author Share Posted November 14, 2018 Hmmm.... reckon i'll stick with regular pots. Thanks anyways Quote Link to comment Share on other sites More sharing options...
SubsonicSimpleton Posted November 19, 2018 Share Posted November 19, 2018 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. Quote Link to comment Share on other sites More sharing options...

They did it on the ebmm USA passive subs and supposedly they sound pretty good. 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.

Bridgehouse Posted November 19, 2018 Share Posted November 19, 2018 (edited) Would a Stellartone Tone Styler do the job you are looking for but without the requirement for two pots and a switch?

fleabag Posted November 19, 2018 Author Share Posted November 19, 2018 (edited) 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 Edited November 19, 2018 by fleabag Quote Link to comment Share on other sites More sharing options...
fleabag Posted November 19, 2018 Author Share Posted November 19, 2018 Still got it. Lobbed in a draw. Dont know if it still works Quote Link to comment Share on other sites More sharing options...

fleabag Posted November 19, 2018 Author Share Posted November 19, 2018 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 Quote Link to comment Share on other sites More sharing options...

fleabag Posted November 19, 2018 Author Share Posted November 19, 2018 Pretty much, yup. But there's always that time when you want to twiddle just a gnats scrote, forward or back, depending Quote Link to comment Share on other sites More sharing options...
