He used an SG with a Maestro tremolo during the Alive From Pachyderm Station livestream.

Larry used PRS Custom 24's from mid-1992 to 2000. He used a Green Custom 24 in '92 and then in '93, he switched to a Vintage Yellow Maple Top Custom 24 for his primary guitar and then a Walnut Custom 24 for his backup guitar. He broke the neck in 2000 at a show in Kalamazoo, Michigan and when it was replaced, he lost Paul Reed Smith's signature on the back of the original neck. He brought it back during the 2015 New Years show and in 2017 for songs from Pork Soda and Tales From The Punchbowl.

This was his main guitar from 1989-1992 and he still occasionally used it for studio sessions during Pork Soda and Tales From the Punchbowl. He can be seen using it in the majority of live peformances at that time. However, his has a maple neck instead of the rosewood in the image provided. He no longer brings it out on tour because he is afraid of it getting broken or stolen.

The HSS Stratocaster Ler uses comes stock with the Fender Atomic Humbucker in the bridge. Ler forgets the name of the pickup even though his tech tells him all the time.

Larry used JCM 800's in Possessed, Blind Illusion, and in Primus up until Pork Soda. He kept it on the distorted channel most of the time, using the volume knob on his guitar to get a cleaner sound until Sailing the Seas of Cheese where he began switching between the clean and distorted channels.

Larry used a white SG for performances in 2006.

This was used on the studio version as well as live performances of Over The Falls in the 90's.

So, yeah, Larry, he chose the DOD Gonkulator. (...) But, the reason I chose that one specifically, kinda like, caught my attention is.. is the amazing quote from him! I don't know, I find it really funny. (...) So here's the quote from Ler: "I hit the switch on the Gonkulator and it made this great robot noise. The salesman said 'Yep, we haven't sold any of those.'" And that's how he chose it.

"He uses a number of other Strats, Teles, and two Fender Pawn Shop Series Mustang Specials." - Premier Guitar.

“Over the years every time I would see an Orange amp I would think “ Wow! That thing looks really cool”. But for some reason, mainly my excellent ability to slack off, I just never got around to trying one out. Then last summer while starting up a European tour I was given a list of amps that were available and noticed the one I was currently using was not on the list. I decided to take every head on the list and after a day of driving everyone nuts with my signature amp testing style (A blend of terrible blues licks and A power chords) it was clear that the Orange Rockerverb was going in the truck for the tour. When we started rehearsals for our current tour we were in a small room so I just plugged in a Rockerverb combo to get started. By the end of that first day everyone had taken notice of how great this amp sounded. It was also so much fun to play through. This is now my favorite amp that I have ever owned. I’m getting every sound that I have ever wanted out of my guitar now. This may be the last amp I will ever need. ”

Larry "Ler" LaLonde used an ESP 400 Series electric guitar, borrowed from Kirk Hammett, to record "Tommy the Cat." This is mentioned in the YouTube video by OutsideOwl, titled "Primus - Sailing The Seas Of Cheese Blu-ray Remaster Info."

Larry uses this guitar currently in Primus along with Strats and Mustangs. He put a Seymour Duncan Hot Rails in the bridge position.

This was the main amp used on the recording sessions for the Brown Album. Live, he used it along with his Marshall and Triple Rectifier during performances in 1997.

"LaLonde, who used Marshalls for a long time, switched to the Fender Super-Sonic 60 for the band's latest album, Green Naugahyde." - Premier Guitar.

According to the Seymour Duncan website, Larry "Ler" LaLonde has used a Seymour Duncan SH-6B Distortion Humbucker in one of his guitars, likely during his time with the band Possessed.

According to the Seymour Duncan website. Ler has used a Seymour Duncan JB in one of his guitars. it's unknown when he used the pickup.

He’s switched to using Orange Dark Terrors and 2x12 cabs. As you can see here, he’s running the Dark Terrors alongside the Fractal Axe-Fx, which helps with covering complicated sounds and pedal combinations he can’t navigate simply with his feet while performing.

Board No. 2 is home to the Fractal MFC-101 Mark II Foot Controller, Keeley Psi Fuzz, Keeley Wolff Octave Fuzz, and a Keeley Dark Side Workstation.

This guitar was used by Larry in Primus' Wynona's Big Brown Beaver music video in 1995.

Larry used this during Tales From the Punchbowl for heavy distortion.

He switched over from JCM 800's to JCM 900's in 1993 and continued using them until Primus' hiatus in 2000. They were his main amps during during the Pork Soda and Punchbowl-era, but in 1997, he began to use them with other amps.

This was part of his live pedalboard in 1993 and 1994. It was a replacement for the EHX Big Muff he used in the studio for the extremely distorted parts on songs like My Name is Mud, Nature Boy, and The Pressman. In the DMV music video, his pedalboard can be seen at 1:18, 3:57, and 4:18 for brief moments. Although you're not able to see any brand name, using the details you can see (color, number of knobs, placement of input and output jack), it's most likely an FX55B.

He used this during the Alive From Pachyderm Station livestream for the songs Those Damned Blue-Collar Tweekers, Laquerhead and Too Many Puppies.
