Does pot taper effect the attenuation of treble? Im asking in reference to regular 10% audio taper pots vs the Fender 30% audio pots. Seems like some upper frequencies get by more with the 30% taper and the 10% pots attenuate more. Is there some truth to this or am I hearing things?
And I know that 10% audio's "5" is 30% audios "2.5" on the dial! :icon_biggrin:

no

+1 on that.
Also, remember what you're hearing is a sum of what's connected to the pot, and what it's being used for...so things like capacitors either shunting some of the signat to ground or coupling to another component. Like when we use different pot' values for guitar volume and tone to brighten or darken what we hear.

indeed, the distribution of possible options/tones across the dual (usually with scale 0/1 to 10) differs with the taper, but not the potential range of tones. In yet other words, the tone at 0/1 and the tone at 10 will be the same, but the perceived mid-point will at, say, 2, 5, or 8 depending on the taper.

Bear in mind guitar amps use cheap crude pots, eg compared to mixing desk faders; the track's end to end value tolerance to nominal is typically +/-20%. The track's conformance to its nominal taper is typically untoleranced, so anything is theoretically within spec.
