Tone idea

[Deleted]

I keep getting my POTS mixed up .. A is LOG and B is LIN !!

Well any way, a normal Tone is 250/500K with 47/33/22/10nF Cap then to Ground.

LIN
1M cut in the middle of the Pots Track so both sides ain't attached to each other any more.
This should make 0-4.9 0-500K and 5.1-10 500-0K with the Common (Middle Leg going off to the Cap)
added with a Push Pull Switch (2P2T {on/on}) you can have 4 Cap Values on the one POT
<just a space saving thing>

LOG
This is the one I am trying to work on. So far I've gotten 2x1M LIN POTs and Painted Silver Conductive Track on one side
making it 500K but only half way (as in a dual pot the Track sides are flipped over so oppsite to each other)
added a 100K resister from the 0-500K to the Common making it in to a kind of FAKE LOG, and the big with the conductive track is the input
going off to the Push Pull Switch (2P2T {on/on})

BUT
The problem is say when one side is on MAX 100Ohms and a 22nF the other side will be 600K with ??nF and still active
---I don't know if i had two Values of par values, ie 47nF with a 33nF on the other side would it make much of a difference (both being so close together might not change the cutt off as much)
+++I am able to stop the Common going directly to the Painted Track by cutting the Inner Circuit at points


So any one can remind me what Pot A&B are (as the old ones used to be A,B and C i think was Rev Log!) Im lost everyone telling me some thing different.
Also any suggestions of ways around my fault, or another way to get more than 2 Tone Types from a Single Pot



1/2PiRC
100nF and 600K 2.7Hz and 500K 3.2Hz
47nF and 600K 5.6Hz and 500K 6.8Hz
Well the 47nF wouldn't be effect the 100nF side as it would need to be a resistance of 1M2
But when the 100nF side reaches 284K its on par with the 47nF 600K, so will be the min it could reach

22nF and 600K 12.1Hz and 500K 14.5Hz
10nF and 600K 26.5Hz and 500K 31.8Hz
So 10nF wouldn't be effected by the 22nF side
again that figure 273K this time both about half way

Perhaps move this to somewhere...not theory and technique...

This is too complex then, some thing that hasn't been done and I think there are faults is a .....just a dream for now

It comes down to the word "theory"
The word time mean is a idea that isn't proven to work. And the use of the word tech in this forum seemed to suggest that this was about Idea's for new ways of doing things tech wise.


well dont matter any way.. been asked not to post.. just an idea i had thats all

To answer the original question, there is no consistency as to which is "A" or "B". It varies depending on the source of the pots, whether from the US or elsewhere in the world.

In USA

A - Audio or Log taper
B - Linear taper
C - Reverse Log taper
G - Graphic taper

In Europe

A - Linear taper
B - Audio or Log taper
C - Reverse Log taper
G - Graphic taper

(the above is courtesy of "the secret life of pots" from the General Guitar Gadgets website)

However, the European designation seems to be "winning out" as nowadays most pots carry the Euro-style designation. But if one is inside a vintage US-made guitar, the pots may well follow the US designations.

Everyone here has long used the Euro designations, as these are more common nowadays. I'm not sure that any pots are still made in the US anymore.

In the section 'theory and technique' we are taliking about 'musical theory and guitar playing technique'. A look at any of the posts would reveal that. It is common practice to move threads to an appropriate section where people might actually see it.

How you construe 'not posting' from a requext to move for those that can, seems a bit bizzarre.
