Good article. But we all know that there are those who are mentally immune to facts.
Interesting that they extended the conclusion to tube amps.
Understood. I have just never seen anyone disavow the importance of a particular cap in an amp as vocally as in guitars, or at all really. Maybe I just don't read as much about amps!No reason not to. The only caps in a tube amp that should be sensitive to value are in the tone stack. Everywhere else, as long as the cap is big enough it makes no difference what the value is.
I too find that a lower value tone gives a much larger usable range on tone pots.
I didn't bookmark it, but I remember reading an article - or perhaps a forum post - where someone argued the benefits of an extremely low value cap (1pF/.001μF) for use with low output PAF types. The gist was that one could take off only the harsh highs, leaving untouched some upper mid content that a conventional cap would be rolling off along with the treble. And that with the knob turned all the way down it could produce a tone reminiscent of a cocked wah.
I haven't tried this but was intrigued enough that I still remember it years later.
EDIT: Found a link for that thread; this is a link for that particular post.

Cool - I'd heard of people wiring a resistor in parallel with 500K volume pots, so pickups would "see" 250K, or using a resistor between switch & pot so a humbucker could see 500K when using a 250K volume pot. But it using a resistor in series with a 500K to effectively have a higher value is a neat trick.Great article!!! Even fully rolled off, the pickup retains considerable character with what appears (sonically) as a mid boost of sorts.
I also add 220k resistors to 500k pots - making them a 720k pot - and on some guitars, I use 1 megaohm pots to get the "bite" that has become an element of my sound.

Adding a resistor in series with a volume pot is not a good idea. The effect is to be unable to reach full volume. You are always at least 220k away from full volume. Swap in a higher value pot as soon as possible to get your power back.
I'm still experimenting with this effect and thus far, the tone has been really good...although I have developed a preference for 1megaohm pots of late...
Bill was way ahead of his time. He also invented the resistor padded coil split, which many wrongly ascribe to Paul Reed Smith.Have you seen the Bill Lawrence 220k ohm resistor added "piggy backed" to a pickup's hot lead to tame the brightness???
