Best Replacement Volume Pot AO 60s Jazzy

Post by Viking Power » Thu Sep 08, 2022 9:50 pm

I’ve tried a few searches to get his info and am just not getting a good answer. Part of it is that I’m pretty ignorant on the different options. Here’s my scenario:

I have a 2019 Fender American Original 60’s Jazzmaster that I recently upgraded with Lollar pups. I’ve noticed that the volume pot is cutting out up toward the higher limit. A little fiddling and it sorts itself out. Annoying though and I’d like to fix it.

I know that the guitar came with 1meg pots. I know that the knobs have set screws. Don’t know other details- split shaft or not, linear or not, etc.

I also know that many recommend moving to a 500k or even 250k pots with the Lollars.

What’s the way to go here and if you have advice do you also have a link for the pots you recommend? Like I said, I’m pretty ignorant with this stuff and looking through the vast array of pots available from retailers leaves me with my head swimming and not knowing what to choose.

Also, do I need to replace the tone knob at the same time as the volume?

Thanks in advance for any help.

The part number is 0095704000 which leads to 1meg solid shaft linear: https://darrenriley.com/store/vintage-l ... 095704049/

Changing the value to a lower one will take off some high end when the pot is at 10. Whether this is what you're after or not is subjective and down to what you are after. Personally, I'd keep it at 1meg and turn the tone knob down a tiny bit and see if that's what I prefer. If I was leaving it at this setting constantly I would consider a lower pot value.

Why did you put Lollar pickups in the guitar ... to change the tone?

Pots and caps have the ability to change the tone too. I usually start fixing a poor-tone-guitar with adjusting pickup heights, then measuring and swapping pots and caps, and lastly swapping pickups. Pickup swaps are few and far between these days since I figured out how much impact the other stages have on tone.

First you need to figure out what tone you want for the guitar. Then move the other parts and set up in that direction.

You may have 'cooked' your volume pot when swapping pickups, and why it cuts out now. Improve soldering skills before swapping in a replacement pot. See youtube for how-to.

Thanks for the replies!

For the record I didn’t replace the pups myself. Had a shop do it. I think the volume pot was already on its way out prior to that though.
In hindsight I might not have swapped the pups at all. I’m not sure the Lollars are all that different from the stock units. People with more fine tuned ears may hear a difference. For me, not so much. What I wanted was a little more ballsy of a tone without losing the sparkle. In other words I want to rock but I also want to surf.

Before replacing anything, it might be a good idea to exercise the pot a little, put in a drop of this, and maybe check that all the solder connections are good.

If the pot is still failing, I'd start with a regular old CTS 1M pot, split/splined shaft.

agree with the above, except I go with solid shaft pots if I want a set screw knob (which i always do).

and when using any kind of deoxit, use it VERY sparingly. too much can cause problems. very rarely is the wiper’s resistance totally worn down, esp on a new guitar. i had 40+ year old pots in my guitars that still worked perfectly fine when properly cleaned.

Apols for the slight threadjack, but I have a similar issue. 2019 mint condition AO 60s Jazz that I’ve had a couple of months. I had noticed the volume witch hat had some minor movement on the shaft, the tone is a solid fit in comparison, and tonight the vol is cutting out depending on how I rotate, bump the knob. Not cutting out completely, but dropping the output considerably.

Any insight is appreciated.

Get some of this and squirt a tiny bit in to the pot (there's a small hole, you'll find it). Then work the pot back and forth a few times.

Check the connections for good solder joints.

If all else fails, swap the pot. Plus, you've got a handy can of contact cleaner for future use on pots, switches etc.

Availability and popularity of electrical contact cleaners seems to vary regionally. I hear Servisol a lot from UK people. Deoxit more from the US. Given the question came from NZ, you'd want to see what is available locally. Servisol is available in Australia (so probably NZ too). So is Deoxit, but you can end up paying $50 for a can. WD-40 do an electrical contact cleaner, not be confused with their general purpose lubricant. CRC is another brand. You'd need an industrial chemist to tell you how much they differ.

On a new guitar it’s nbd, but a lot of people just grab whatever is in a spray bottle and squirt some in.

Which can work… for awhile.

But especially on valuable older gear with original parts, it’s best if you use the right product for the job.

I don’t use the same stuff on switches that I use on pots, for instance. I have a few different products I’ll use on pots, sometimes multiple in succession, depending on what’s wrong

Thanks for your comments, guys. I am in NZ but bought some D5 & F5 Deoxit from the States a while back.

The pot is just a bit weird where it’s not just the rotation but it feels a little loose. And that slight movement on the shaft can be enough to drop the output.

From the symptoms and mention of looseness of the shaft itself I'd suggest it's been impacted at some point in the past - and the easiest lasting fix would be to replace it.

Perhaps, although it seems unlikely. It’s a 2019 in mint condition. I’ll give it a spray and a tighten up.

Cheers all.

I agree that an impact sounds plausible.

This could’ve occurred in freight transit, even slamming against the inside of a hardshell case.

If cleaning and lubrication doesn’t resolve the issue, replacement is easiest.

I’ve rebuilt several vintage pots, but on a new guitar that would be more trouble than it’s worth

Ok, so finally bought some deoxit and sat down to work on my guitar.

Dude! This worked! Saved me who knows how much I might have spent getting it looked at in a shop. Also a good confidence builder for opening up my guitar and doing things myself.

Thanks!
