Just wired up 2 humbuckers,master vol amp; master tone and 3 way switch.When i turn down the tone there's no change until the pot is almost fully down.Pots are 500k and the cap is 47.Any one help.

These kinds of problems can be tricky. The first thing I'd check is, make sure you have a .047uf cap, and not .47uf. (Or worse yet, .47mf.)

or 4.7 F
seriously though, make sure the pot and cap arent fried too

i like to use a heat sink on the leg of the cap when i'm soldering it so that it gets hot on the tip where i am soldering, but the heat doesnt travel up the leg to the cap itself

good luck

Hi guys i've used new caps to make sure they are 047,new pots 500k,checked wireing diagrams to make sure that's ok,but still no change in tone until almost right down.I'm useing 2 hums with master vol,master tone would that make any difference.

Here the Jpeg file for wiring

Are you using audio or linear tapered pots? If you're using linear tapered pots, it could be that you have it wired up properly, but you're not hearing the rolloff of treble frequencies in a smooth fashion due to the pot's design. I've never liked linear pots for that reason...to me, they are counterintuitive. You would think that a linear taper would give you more precise control, but it actually works just the opposite. When I tried linear tone pots, I couldn't hear much difference between 3 and 10. There wasn't any noticeable change in the tone until the pot was almost turned down to 0.

The thing is, an audio taper pot will roll off the volume, or the tone faster than a linear. When you have an audio taper at the halfway point, you only have about 10% of the resistance left to go. With a linear, you'ld be at the electrical halfway point.

Edit: Deleted the part that was based on a misread.

True, but to my ears, the change isn't noticable until you've turned the pot way down. That's why I never liked linear tapers. Audio tapered pots may appear to have a strange taper, but that's how our ears hear things. To me, they sound much more natural than linear tapered pots.
