Volume pot issue (Cap output neck PU)

[dudiluty]

Hi there.

I've recently installed a 0.47 orange drop cap(Seymour Duncan mod) on the hot output wire of my neck pickup (stratocaster) but I have one problem. When I roll back the volume it's not really smooth anymore.. It's more like a drop in volume at point 8/9 and then goes on fine....

The cap sits between the pickup and the switch.

Can anyone help me?

Here is picture of the wiring with the cap. (Strat has 50's wiring)

It sounds like you have a linear tone pot. A .047 cap will cut not just highs, but a lot of the mid range as well. The guitar lives in the mid range . . . so rolling back tone with a .047 cap will drop volume - that's expected. If you use a linear taper pot, this roll off tends to happen most dramatically in the first couple notches of the volume knob. I find that audio taper pots are more gradual in the roll off.

Edit - nope, looks like you've got an audio pot installed. Might be related to the '50s wiring then. This type of wiring links your volume and tone pots so that they both kinda act as one another depending on that values you've turned things too.

I suspect that you have your 5-way wired backwards. (Easy and common mistake.) You definitely have the cap wired to the "bridge" position contact. (Handle all the way back.) Also, did you intend to tie the bridge & middle together to one tone control? That's ok, but typically, people would tie the neck & middle together and then use the rear tone for the bridge.

Uhm I think the neck middle and bridge is wired correctly? See the pic..

Like this? And then use jumper?

Right. Notice that the bridge hot wire goes to the top-most left terminal. That's where your cap is. But in your text, you say have the cap connected to the neck pup. That's what's confusing me.

I wired it incorrectly I can see. Tnx.

But I did wired the cap to the neck hot output.

So a jumper wire on 3 and 2. And leave 1 only for the bridge?

Well I got it fixed! I Was the volume pot it self.

I have opened the pot, cleaned it and gave it some contact spray and it worked perfectly again!

I also rewired the whole guitar with clothe wire.

So now I have 50's wiring, with tone control and split and a cap for the neck pickup to reduce the lows against muddy sound.


Thanks for all your help guys!

I love this.
