Les Claypool

Primus is listed on Shure's website as a user of this microphone at "What they use". Les Claypool uses this mic for "dirty" during songs like "Tommy the Cat", and "My Name is Mud" and this can be seen at live performances.

In Bass Player Magazine, Decemeber 2017, it states in the segment "The Many Colors of Les", "According to tech Ryan Becker, for live shows these days, Claypool's basses feed a Shure UR4D wireless system"

Les Claypool, vocalist and bass guitarist of bands such as Primus, The Claypool Lennon Delirium, and Duo de Twang is shown playing a live 2016 performance with a modified Regal RD-05 Resonator Bass Guitar. He has the 3 port holes covered with a pickup which does not come stock on these models. All of his performances with "The Claypool Lennon Delirium" so far have featured this model which he has been cited as naming, "The Dobro". Truly a wonder of nature this bass is, if there ever was.

Les Claypool is known for making music not considered "normal". As not "normal" as his music is, he uses a Whamola, a 1 string upright bass with a lever behind the neck to change the pitch. It is clearly seen starting at 0:20. A short clip of it being played is used in some versions of the theme song for "South Park".

Taken from the Carl Thompson official website, there's a section dedicated to the bass guitars that Les bought from him!

The Carl Thompson site features Les Claypool and his basses. The source image is linked directly from the Carl Thompson page.

The bass also gets brief mention from Claypool in his Vintage Guitar interview. This bass was used on "The Desaturating Seven".

I used my six-string fretless Carl Thompson I call “The Rainbow Bass” quite a bit, which I hadn’t done in a while. So, I think that was exciting for people who are fans of that thing. There was also my NS upright and my black Pachyderm bass.

Used in many live performances, such as on Late Night with Jimmy Fallon, and also seen and demonstrated briefly here in this interview with Boing Boing Video on the Oddity Faire Tour + "Fungi or Foe".

A red one can also be seen throughout the music video in "Wynona's Big Brown Beaver".

Les Claypool has been seen in live performances with this bass. He's seen in this performance with Gov't Mule performing with the red 4003.

In this photo, Les Claypool of Oysterhead and Primus, is seen playing his Carl Thompson - Maple Piccolo Bass.

Designed by Les Claypool and made by Les’s longtime friend and luthier, Dan Maloney, the bass was made to be the most comfortable and easy to play four string basses to his standards. This was one of two original basses that Les performed with onstage with Primus and has a walnut top with a maple back and exotic wood pick guard. It is 32” scale with LED lights in the side of the fingerboard and has a Kahler brand tremolo bar. Keeping the electronics simple, it has one single custom split EMG pickup with a single control knob. This combination of woods and electronics gives this particular bass a warm but punchy attack with a medium finish. This bass was auctioned in 2013 to help pay for the medical treatment of Les' nephew, Baby Matthew.

In this video, from the performance of Claypool Lennon Delirium at the Outside Lands Music & Arts Festival 2016: for "Astronomy Domine" by Pink Floyd, Les Claypool briefly abandons his Pachyderm Bass to play an EKO 995 Violin Bass.

This is one of Les Claypool's main basses. It has a Kahler Tremelo equiped and one EMG 35. He uses this on songs such as "Those Damn Blue-Collared Tweakers" and various other songs.

In this performance, you can see Les using a 70's Jazz Bass. FYI, both pickups seem to be on full.

In this picture from Summer 2018, Les is shown playing a Thunderbird model bass.

In this image we can see Les standing in front of his stage set up. The 400+ can be seen to the right of Les.

Les is shown in this image standing next to his live set up gear; including the Mesa Boogie 2x15 Diesel Cabinet.

According to Ampeg's site, it says that Les uses an SVT 3 Pro.

......................................

Early to mid 90s, modded MP-1 guitar preamp through the Mesa 400+... Can't find any definative proof but back in the day he was on the back page of just about every guitar player magazine advertising for ADA...

He's been using these amps for a while now

He uses this as a head for his Mesa Boogie Subway Cabs

Les Claypool used one or two of these at a time placed horizontally and angled towards him for a period of time and can be seen with this setup live on several occasions.

Les Claypool uses this pedal for the album "Animals should not try to act like people.

On this vídeo there is a quick shot of Les Claypool's pedalboard from 0:27 to 0:34. It is possible to see clearly the Line 6 DL4 and DM4 and the Roland PK-5.
