1:40 - How long should a note be able to ring?
2:42 - Quality of sustain
3:24 - The spreadsheet
4:23 - The amp's role
5:07 - Testing break angle
6:11 - Testing saddle material
7:14 - Testing string tension
8:01 - Testing absence of neck pickup
8:42 - Testing resonant mass
9:50 - Testing the finish
12:18 - But what makes an obvious difference?
14:00 - Outro jam
Tests were done plugging the guitar directly into the computer for a clean signal (except the amp feedback test and neck pickup test).

It's really cool to see people enjoying the tone tests video I put out 2 weeks ago.
Sustain wasn't on my mind when I was making it, but there were some people in the comments talking about sustain so I thought I'd spend some time figuring out where it comes from.
It was fun coming up with the tests, trying to find limits and do everything I can to stop the guitar from being able to hold a note. Hopefully people who watch this video will have a better idea of which things play a role in sustain, and how big that role is.
Also, I bought 2 of J.T. Corenflos' cabs on Saturday and the background music for this video is the first thing I've used either of them on.

This was a good video on sustain. It could have been longer though.
-
This guy's dry humor combined with total willingness to shatter most guitar players' concensuses without even saying a word about it is amazing.
-
"... so I did that" had me rolling. WOW DUDE. The commitment to these tests are just insane.
-
Seems like a lot of these myths about tone and sustain relate to acoustic guitar, but don't really carry over to electric in reality, yet have been perpetuated for decades in the musical community. Brilliant, enlightening video, as always!
-
This is like "Mythbusters" for guitar, and I am loving it.
-
It's really a pleasure to see an empirical approach to what so many people treat like magic.
-
The fact that you put yourself through all of these tests is insane.
-
As a physicist, I find it interesting that the sustain was better with lower tension - with open strings. When the tension is lower the frequency is lower, and that means the string goes through fewer resonance periods in the same time. The Q (quality) factor is an important parameter for a resonator, and it tells you the fraction of power lost in a single period. If the Q factor stays the same but the period increases, you have more sustain.

"So I did that!" Hats off for thoroughness and commitment. Love these videos.
-
The combination of these 2 videos really makes me think that practically the only things that truly matter to a great sounding guitar are a good pickup and a good setup. And a great player of course!
-
I'm convinced. I'll never soak my guitar in glue again. Kudos to Jim Lill and his "Tested" video series for creating the most interesting guitar content on YouTube.
-
I’m fatter after covid and my general sustain in each of my guitars is by far better… When I was less soft, things had less resonance for sure. You and your studies are incredible! Stay Awesome
-
This is going to turn into a series called “everything you know about guitar is wrong” and we’ll all be playing the Jim Lill signature squier bullet telecaster with Seymour Duncan pickups that only costs 249.99…
-
This series could be used in schools as an applied science class. So freakin’ clear and thorough. And zero time wasted.
-
As a builder and repair person, i rate this guy as a national hero.
-
I appreciate all the effort you've put into testing long held, and inaccurate, beliefs in the electric guitar world. Strings, pickups, and signal processors are the most important parts of an electric guitar signal chain, period.
-
These make me so happy because it just confirms that as long as a guitar is built properly and the pickups are ok, there’s no reason it can’t be a usable sound
-
Interesting. Makes me think that perhaps the higher perceived sustain on a Les Paul vs a Tele might be the fact that the Les Pauls will tend to have higher output pickups, causing the amp to break up more easily.
-
I fucking love this guy man. I can hear the cork sniffers sharpening their pitchforks.

The Edge used an Infinite Guitar, built by Michael Brook, on the album version of With or Without You, but used an EBow on tour to play the song. In case anyone was wondering.
