Pot Shootout: 250K vs. 500k, audio vs. linear

I'm confused by the 5-8 Timbre thread in that, while they're all labeled as bridge pickup only, #6 sounds completely different from that other 3 - and sounds very much like the last two samples - where both pickups are full on. Is it possible #6 is both pickups on? I can't imagine simply changing the volume pot from a 250k to a 500k - all else remaining the same - would result in THAT big of a difference. Additionally, 5, 7, & 8 all have that soloed bridge midrange quality, while #6 doesn't.

does anyone know if these $1.99 mini 250k linear pots really have a decent linear curve? need a small one to put in this korean squire II p bass the bass is very bright and i am hoping witching from a 500mini audio to the 250k linear will tame the brittle high end with round wounds and stock ceramic magnet pickup(s)
thanx, p

What is a decent linear curve? The wafers used in pots are of linear taper. If you want a nonlinear curve, then you join multiple segments to approximate that curve. But if your desired taper is linear, then one segment approximates that curve exactly, because it is already linear.

they'll do for volume.
 
what did you settle on and why?
For the pot values, 500k volume with 250k tone sounded best to me. The 250k volumes were a bit warmer, and the 500k sounded a bit brighter and punchier. Also...both pots being 500k sounded a bit more mid-rangey than Id like.

With regard to tapers...definitely Audio for the tone pots. The audio taper on tones seems more gradual throughout the turn of the knob...with more useful space to dial in my settings. The linear tone pot seemed to go through its usable range far quicker...which would give me very little room to work with in terms of making incremental tone changes.

For volume pots and their tapers...oddly enough...I had the opposite feeling from my ears. From the sound samples I listened to...there's much less usable portions of the audio taper in my opinion. The audio volume seemed to have more silent space on the knob...which Id take to mean fine tuning would be a little less precise. It seemed like nothing happened until halfway through the turn...and then came a gradual rise.

Linear volume seemed to have less of that silent space....thus more usable space on the knob. However, the initial rise in volume at the beginning of the pot's turn was more abrupt. Because of this it seemed like medium and higher volumes can be dialed in easier since more of the knob is useful. But lower volumes seem like they didnt have as much usable range since the volume increase came out a bit quick at the start of the turn.

That all said, I wish I knew if what value pot was used with each particular taper. The available samples don't split that up.

I think there are "vintage" taper pots that are in between audio and linear taper. You might try one of those for the volume pot ...
