Just thought I'd toss this out and see who shoots at it: I recently found one vendor's page where they're selling 1 Megohm and 2 Megohm volume pots, suggesting them for use with hot (and hotter) humbuckers.
I thought about trying a 1 Meg log-taper push/pull pot (CTS makes 'em) to be able to switch in a 422K or so parallel resistor. That would knock it down to not quite 297K, which I think would reduce the IPITE effect when the pup was shunted to singlecoil status. That resistance might also be agreeable to some HBs.
And something I found in the glossary on Kinman's site: "Dopelar Effect The tendency of stupid ideas to seem smarter when you approach them quickly enough." ;D
Opinions?

... "Dopelar Effect The tendency of stupid ideas to seem smarter when you approach them quickly enough." ... "DOPE-lar effect" that's golden pal! "there's always more than one way to skin a cat" seems to be my phrase of the day, so let's think about a few things, and see what sort of ways you might sneak up on this this kitty. the reason you would want higher resistance volume pots for hotter humbuckers is: in general, hotter humbuckers have more inductance, so the more you load them down with lower resistance pots, the more you lose the treble. so if you want to reduce the treble in situations where the inductance is lower, adding a parallel resistor would be one way. another would be to experiment with using a resistor and cap in series and putting that combination in parallel with the pickup. i expect that would allow you to tailor the losses so that it would be limited to the higher part of the treble range (you know the IPITE part). of course that pure specualtion on my part and would be highly experimental on your part. having it switch in automatically in the configuations where the IPITE factor is involved sounds like it would be highly desireable, as would having it switched out when not required. the other drawback to ultra high resistance pots would be that at intermediate settings, the output impedance to the cable would be higher. that means high capacitance cables will cut the highs at the intermediate settings. also, the higher impedance means more opportunity for hum and noise to find it's way onto your cable. things get a little complicated when you try to get the best of all worlds, but if you plan things out and experiment a bit, you just might be able to come up with something worth doing here kitty, kitty, kitty |

no personal experience with this problem, but the very same Kinman's site suggest a double gang pot: "Mixing Single coils with a Humbucker: There is a fundamental problem with mixing single coils and humbuckers because they require different value Volume pots for optimum performance. However if you really want to do this and have optimum performance from both types of pickups you have to accept this situation and be prepared to provide separate volume pots for them. One solution is to fit a dual ganged Volume pot that has one 250K track and one 500K track (Stacked or Dual Concentric 'A' curve pot 500K/250K is available from Allparts (USA) Part ID EP4585-000). Another way to do this is to reassign the middle Tone pot to become the second Volume pot and then make the remaining Tone pot operate on the single coils only (don't make it common to all pickups as it will muddy the humbucker even more). I will provide a special Wirogram for these configurations only to Kinman customers.....(Contact me)." www.kinman.com/html/toneWorkshop/perfectGuitar.htm#SSHApart from the sonic attributes the curve of a 1Meg pot isn't as smooth. Other than for reasons pertaining to tone, the 1m might not be such a good idea. |

I've had somebody else tell me that he wasn't happy with the taper effect of a 1Meg. Based on that and some of the other stuff, I might just shelve the idea, for this project. I might try it with the 500K pots, though, dropping them to around 300 for those times when either/both shunts are on. (2-13K HB (for which they suggest the 2Meg pot), 2 vol., 2 tone setup.) |

I got a big yok out of that, so I thought you guys might, too. Kinman's got more than one of those thrown in there. Resistance, impedance, capacitance; next it'll be reactance and that hysterics stuff. ;D Experimenting is always fun. "IT . . . COULD . . . WORK!" {/Gene Wilder as Dr. Frankenstein} |

Have you thought about the old school way? I have an Ibanez Pro540R that I changed the bridge pickup to a Kramer Quad. As you may or may not know, the Quad is a muddy pickup. The output is HOT, but a bit on the muddy side. So I added a .001 capacitor on the single volume control. As I lower the volume, the cap lets the high frequencies pass. (Fender tele's from the 50's had that.) True, the volume is lower, but if using it through an effects pedal, it doesn't matter that much, and straight to a board, it's quite nice. Simple to do, so give it a try.
