What's you favorite tone cap value?

I think it depends on the bass and pickups; in my experience, it's not quite one-size fits all (although a case could be made for .047). I think .033 uF is an overlooked value that has great potential, too, since it leaves more mids intact than .047.

I've rewired my Hofner to have three cap values (plus bypass)--.0068, .03, and .062 (just because I had .047 and .015 caps handy and combined them). The tiny cap gives a wonderful woody tone with a hint of P-bass grunt. The .03 is smooth and round (but still with solid mids), and the .062 is my dub tone. Mostly, I switch between .0068 and .03. (Bypass and .062 are 'bonus tones.') I arrived at these values after also trying .015, .022, .047, and .1 uf caps. All of them were lacking in one regard or another, with the lower values being too honky.

On the other hand, .022 sounded great on another bass (with a MM humbucker, wired passive with coil switching). I tried out a variety of values and settled on .022 and .047. (.047 sounded best with the pickup wired in series; .022 sounded best with the pickup wired with the G&L OMG-style 'bass boost'--a .1 uF cap wired across one of the coils.)

The upshot: it's worth hooking up a couple of leads with alligator clips and trying out a handful of different values. It's quite interesting and a cheap and easy way to help dial in one's sound.

I have no idea what my favourite value is. I know that I had two caps in at one point t up the overall value.
At that point the bass didn't open up as far as before even with the tone all the way open. No idea why that was( anyone here know?).
I removed one cap and have used it like this since.

Did you have them in series or parrallel? Caps are the oposite of resistors, you need them in parrallel to up the value.

I don't know...
The value did go up with the two as in; more top end was cut. The problem was that when the pot was all 'open', it didn't open up as much as when only one cap was in...or as much as when two caps of lower value were in there.
Is this normal and if not...why might that be?

It could be that the pot does not actually go completely to 0 ohms. So the larger the value you put in, the more highs lost even with the pot "off".

They actually sell no-load pots that are guaranteed to be off when set to 0.
