Thundercat

This video is such high quality that at around 2:20 onward you can literally read "Shure SM58" on the mic. Great video!

Thundercats Ibanez signature 6 string

Thundercat is playing his custom made maple MTD electric bass. In this article Bass Player writes "My MTD cuts like a knife. The body and the neck are all maple, so it’s like a super shank."

Thundercat is playing a modified Ibanez Artcore bass in the photo; possibly the AGB200. The end of this interview with Bass Player lists a custom Ibanez Artcore 4-string bass as part of his gear.

Thundercat is shown in this video playing an Ibanez double-neck bass while performing live at the Hollywood Bowl in 2016. Song performed is "What a Fool Believes" featuring Michael McDonald of Doobie Brothers fame.

Speaking on the double-neck bass in an interview with Guitar Hero, Thundercat states, "It’s fantastic. It’s got this Pink Floyd-ish tone that’s really open—it rings out because there’s the 6-string on top and an 8-string on the bottom, both with EMGs. I wanted to go for that vintage P-Bass sound, but there’s hardly any lacquer on the wood, and it’s like this open “baaaaang!” It’s pretty funky; it has its own life."

At 1:16 you can clearly see the Aguilar DB 751 with two 410 matching cabs.

Thundercat - Stephen Bruner - gave an interview to Bass Player magazine in which he went into light detail about some of his equipment, and they've listed some at the bottom of the article linked. You can hear examples of these pedals being used in tracks like 'Oh Sheit, It's X!' and 'Them Changes'.

You can see thundercat adjusting the low pass throughout the video. He's been known to have the signature "moogerfooger" sound.

In this live clip he's using some kind of octaving effect, with excellent tracking, and the first visible glimpse of a large red pedal is at 20:05 https://www.youtube.com/watch?v=a7aBs66HXrU (It's gotta be a Whammy).

Also here, a Whammy is clearly visible on the desk. https://www.youtube.com/watch?v=zhVgbZdMdb0

"The Pigtronix is powerful—it reminds me of a Mu-Tron Bi-Phase, but it’s nice not to have to deal with the weight of a Bi-Phase."

The cat is clearly seen adjusting his Whammy pedal and this bass synth wah at 6:20 in this video

Check at 6:20 when you can see the effects that he has on the table. And when he starts playing the song Them Changes you can clearly hear a phaser along with an octave up from the Whammy.

This white phaser can be seen next to the low pass filter throughout the video

in the video at 2:19 you can see the Apogee Beast.

In the Video he wears that Can.

The article, in its introduction, says that as well as using his custom-shop MTD six-string, a "16th note bebop runs on... a semi-hollowbody Ibanez Artcore".
