Should I Replace The Volume Pot?

Postby GonzoBass » Sat May 29, 2010 12:28 pm

The tone on the Steinberger had a bit of scratch,
so I pulled all three knobs yesterday
(Vol Vol Tone)
and gave 'em a good shot of contact cleaner down the shafts.

When I replaced the knobs,
I overtightened one of the allen screws
and broke off half of the split shaft on the neck volume pot.

Questions:

What are the chances of changing the overall tone of the bass if I replace this pot
and if this is a danger,
how can I go about getting the right pot to prevent this?

Thanks in advance.
I'm more than just a little paranoid about tinkering under the hood on this one...

Damn. There is a good shaft joke here, but I am coming up empty.

Mark?

Gonzo, I don't think you have a lot of options. But if replacing the pot does change the tone, just start looking for a parted out bass of the same vintage and buy the pots.

Another option would be to replace the broken side with a split wooden dowel. If the knob is a screw-on type - gently tighten it onto the remaining side of the shaft until snug (don't over tighten of course) - if it's a a compression fit, just shave the dowel until it fits. If done carefully and very snug, you can get some mileage out of the fix.

or use part of a bic pen cap.
If the (audio) taper and value is the same a change shouldn't alter the sound or the direction of the canoe ( jus' sayin' Gonz you know the shape and everything) [smilie=fun_84.gif]
I would take the oks V Pot with me to Radio Shack or wherever and have them read it a nd dupe it if it were me.

As it is now,
the allen srcew was long enough to reach snug onto the remaining half,
so it's working,
but scary to think that one good bump could break it off completely.

It does get bumped...

As long as you replace the pot with the same type pot (value/taper) with a quality replacement (i.e. CTS) there isn't much of a chance of changing the tone. ;)

Yup. [smilie=grinning-smiley-003.gif]

Guitar Parts Resource, Stewart MacDonald, Allparts (a.k.a. Butch Ammons or John Wymore ;)) are good sources.

I'm not exactly sure what the XP has in it, but I believe yours is all passive with the EMG Hi-Z pickups. A quick check under the hood should tell you what value you need.

My L2 (s/n #1156, 9/27/83) has active EMG pickups and passive electronics. One of the pots is kind of scratchy and another kind of worn [they have a lot of miles on them, not as much as yours, but a lot] so I'm probably gonna replace all three pots myself.

Another thing, when you clean your pots, a standard contact cleaner only does ½ the job - it cleans the dirt/debris. The pot needs to be treated/lubricated as well. Without lubrication the pot will wear out sooner just like a bearing or any other moving mechanical part. I recommend using Caig DeoxIT 100 on pots. Either the spray or the squeeze tube.

Thanks Gil!

Yes, mine is a passive XP2
and I'll definitely look into the DeoxIT.

I realize I am way late for this party, but replacing a volume pot isn't going to effect your tone as long as you use the good stuff. Pots are mechanical, and they wear out, and they need to be replaced every so often. This is one area where vintage is not better than new. And +1 for DeOxit, great for all sorts of connections like mike connectors, instrument connectors, etc.

FWIW... If you're restoring a vintage guitar, using period correct harnesses, will add value. Strange but true. But ya, as Rand stated, they are like windshield wipers, or what we call in my industry, consumables.
