1/4 Jack Tone differences(?!)

Hello all,

Went to replace the 1/4 jack on my cabinet due to the old one looking a bit rough due to the previous wiring from the factory (They had a built in attenuator installed that was always slightly in the circuit that I had to remove).

Was just going to buy one when I thought about the various options available.

I found this comparison on YT and almost could not believe my ears.

They actually sound different??

I did not think between the same metals and style of jack, there would be this much of a tonal difference heard.....

What say ye, RigTalk??



 
I can hear the differences in that clip but they've been tested in a fuzz pedal which presents a high impedance scenario. Those differences are far less likely to be audible in a much lower impedance case such as for the speaker level loads.
And I'd like to mention, just because it will bother some to no end, that I recently had a couple of my guitars outfitted with Analysis Plus Qijacks (output jacks). Now, both guitars had new pots and some new wiring done as well but they do sound better now (more fidelity is the best description) with a slightly lower noise floor too.
 
i think we just hit a new low. soooo jacks change tone now

At one point in time many moons ago, this rabbit hole is something that I might have explored. God knows I have dove headfirst into many others. Today, not so much.
 
I did some experimenting and.....

The slight roundness I was trying to dial out of my amp is gone after switching away from the Cliff style jack I was using.

I tried a gold jack lying around, but it does what gold always does to the sound and I dislike it.

Something about the way I do harmonics and gold connectors, or apparently now jacks, cancel eachother out. I am left with this weird scratchy shriek instead of a juicy screaming harmonic.

Found another Nickel switchcraft style jack and soldered it in.

Much more bright and open.

Way easier to hear the detail as compared to the Cliff.

I have the standard Switchcraft #11 on the way now to be installed and left in, I am certain.

The top end stays very present but nice and pleasant thanks to the AV75s.

If you are seeking to dial in/out a specific sound from a cabinet - like maybe it sounds a bit round, check the jack it is using and see if it is a Cliff style!
 
So, I am not certain if it is just my setup that reflects all of these minute changes so well but my experiences are matching the video note for note.

1) -Cliff jack.

Everything was rounded. Not bad overall, but could definitely be better. The guitar hides a bit behind the gain and low/top end. Probably due to less mids. Sounds a bit scooped maybe if I had to graph it with increased bass and treble frequencies that the sound sits within. A bit of a noise floor when changing to other jacks, could just be how the guitar is more 'hidden' in the background of the soundstage.

-2) - Switchcraft gold #11.
Dislike how it shaped the overall sound. Accents certain frequencies, pushes down others, and almost mutes my pinch harmonics. Like the scream of the harmonic now sits in the very back, as opposed to the front of the soundstage. Going between multiple guitars, this is not the jack for me. The top end is present, and there is a certain open nature, but it just isn't for me. Not the first time I changed an item to have gold connectors or the link, and disliked the change.

-3) - Random
Swapped to a jack I had lying around that is unmarked but resembles a Switchcraft MILspec style jack. This sounded great, with a much lower noise floor/dead silent, with much more focus on the core guitar sound. Really a ton of fun. Thick and punchy with plenty clarity. Harmonics sit where I want them again. Absolutely punches you, but not bassy or woofy. The low end is controlled and tigh and the top end is present and clear, with a bit of thickness and a touch more warmth/wideness to the notes.

-4) Switchcraft #11 (Standard/Nickel) -

Extremely bright and open. No competition if you are looking to brighten up a dark sound. Has me wanting to set my 2x12 on its side again. This would work really work in a closed back cab, which can sound boxy. Effects like reverd and such are super shimmery. The pinch harmonics are there, and scream, but there sure is a lot of top end clack and openness to this sound. It takes away a bit from the punch and body of the notes. I use my cabinet open back. Rotated through several guitars, and even dark ones are sounding on the bright side, even as I roll off on highs. This probably works better for most people in a live band scenario - lots of cut and top end. I do not like this for my setup.



I may get some speaker cable in the future and wire in a second output jack. I can then A/B the setup, the only change being the amp cable going from one input, to the other.

When I get the speaker wire in the future, I will be sure to rig it up for the test and go through various makes.

The difference here were far more vast than I would have imagined.

Listen to the video with good monitors - it nails some differences that I myself heard.

The switchcraft will be - hads down - the brightest and most open of the lot.



As for this cabinet and setup - I will reinstall the random jack. I am going to savor the mysetrious bit of gear magic I have stumbled upon.
 
Yes, just installed the random jack again.

Could NOT stop playing. Didn't have to turn a bunch of knobs to try to get the sound I wanted...there it is again....

So weird. I would never have ever guessed.

Great info brother, thanks for taking the time!
 
This is corksniffery the likes of which not even God has seen, outside of TGP.

Eric Johnson preferring Carbon Zinc to Alkaline 9v batteries comes nowhere near this.
It seems you’re quite the jack off artist as well;

“you don't like the Mesa 8 ohm V30's, it may simply be the sound of the momentary contact jack and parallel-series wiring of your Mesa cab.

Rewire it series-parallel with one jack and profit.” From Nigel, on Aug 17, 2025

You know what's funny - I have a friend who EJ was a frequent customer of.

Said to sell him any cables, you had to send him an entire box full of them, and he would buy the ones he liked and send all of the rest back.

Same with selling a guitar to him.

He had to have a good cable he said, before he could decide to make a purchase on a guitar, because the cable affects the tone and he did not want it to skew his decision.
 
I don't know why people are giving you crap but yes everything in the signal chain has an effect and its good to know where the differences are. Unless you have a dark amp / setup most people don't really care but yeah it can make a difference.

Having knowledge of these things at least gives you options if you're ever starting a build from scratch or are in there replacing things anyway. If you have a reference then you can decide whether or not its worth a few bucks to brighten things up a bit or round em off based on your setup. Cheaper / better than an eq

People are strange. I ended up choosing the random, no name jack I probably ripped out of some guitar that came across my bench. You think that would be the opposite of cork sniffing but hey....

You are absolutely correct! Everything in the chain makes a difference. Some moreso than others. In this case, large enough of a difference I think the average person can hear it, even with the compression YT adds.

I've had two Solid Cables Arc Ultras for nearly 20 years. I want for nothing...gave two 21'ers to Doug Pinnick for he and Ty because honor and respect your elders is a thing. I wonder what EJ and Ian Thornley use.
 
I’d like to see confirmation that the temperature was the exact same for each clip. Fuzz pedals are known to sound different based on temperature. (germanium)

Don’t forget to clean jacks on guitars, amps, cabinets, pedals, etc. They get dirty and corrode. Also, clean all cable ends. I try to do this at least once or twice a years with everything I own.
