This photo shows Trevor Dunn playing his customized 1991 Alembic 5-string Europa bass guitar. On his official site, he talks about the details of how he came to own it and how he customized it:

"So I met this guy at a Bungle show who happened to work for Alembic. He got me a good deal and brought me to the factory up in Santa Rosa, California where I was able to pick out the actual pieces of maple that would be used on the front of the body. Since it was being made from scratch I customized it in a couple ways: I had them refrain from putting dots on face of the ebony fretboard. It looks cool but it really messes with your eyes and took me a while to get used to. Luckily there are dots on the side of the fretboard. I also had them use a left-handed head-stock for that Hendrix look. Unfortunately this puts the E-string tuning peg out of the reach of my stumpy little arms. Oh well, there's no other bass in the world like this. I used it on Bungle's DV & CA cds as well as Zorn's The Gift, but I don't play it that much these days." – Trevor Dunn on his 1991 Alembic 5-string Europa

This photo shows Trevor Dunn performing live and playing his 1975 Fender Precision bass guitar. On his official website he says:

"Around 1998 I got the vintage bug and decided that I had to have a Fender P-bass. I went to Univibe in Berkeley where they had two. I picked this one up and it felt the best so I bought it. It has since been my main ax. I had a BadAss bridge put on and I had the nut and bridge at the E-string cut to fit a low B-string. In Fantomas I string it B-E-A-D, but for everything else I use regular tuning. Somewhere along the line I decided to start putting butterfly stickers on it--maybe out of contrast to the music I was playing. So, I call this my Butterfly Bass." – Trevor Dunn on his 1975 Fender Precision, from the GEEKING OUT section of his official website.

Trevor can be seen playing a 1966 Starfire Bass at 1:05 in this video. He talks about this bass on his website, saying, "It records beatifully and feels amazing. I have flatwound strings on right now. I believe it was made in '66 but it seems like most Starfires from that year have the neck pick-up whereas mine is closer to the bridge. I've used this bass on some of my own film music, Zorn's The Dreamers and some stuff with Yuka Honda."

"The strings are made out of silicone and sort of look like snot, so I started calling it the Booger Bass. I used it on Bungle's Golem," says Trevor, about his Guild Ashbory, which Trevor's dad bought him in the late 80's.

In an interview with Guitar World, Trevor Dunn mentioned using the Gamechanger Audio Plasma Pedal during the latest Mr. Bungle recording session.

On his official website, Trevor Dunn talks about his preferences when it comes to bass amps. He lists out his Acoustic Image Focus 1 Amp Head:

"When I play with the Melvins or Fantomas I have an Ampeg SVT Pro-4 out in LA, or I'll just use whatever crap Buzz has lying around. Honestly, when the sound is about pushing air, I'm not picky about gear. As long as I have an 8x10 cabinet I just keep my EQ close to flat and work from there. Also, I rarely bring my own amp to the recording studio. I use whatever good stuff is sitting there, like an Ampeg B15 for example.

What I AM picky about is my upright sound. I used to HATE amplifying my upright but I've learned to deal with it. I still like SWR so for really small gigs I use a Workingman's 10, or as I like to call it, the Lazyman's 10. It's super portable, although not very loud and not the best tone. When I can, I use my Acoustic Image head. It too is super light but sounds incredibly natural to me and is versatile in terms of EQ. It can get plenty loud and I've also used my electric with it.

I still have my SWR cabinets that I use with this head. To me, that's the perfect combo with my upright." – Trevor Dunn on his Acoustic Image Focus 1

"For years I used an SWR SM-400 with the Goliath Jr 4x10 or 2x10 for smaller gigs. I burned it up on the first Fantomas tour and it hasn't been the same since. At that time I bought a GK 800 as a spare but now I use it for loud gigs." – Trevor Dunn on his Gallien Kruegger 800 RB

"It was probably built in the 1950s. Since I've had it I've replaced the bridge, fingerboard and wooden tuning pegs. Usually I use Thomastik Superflexible strings (rope core), but currently I'm trying out the Bel Cantos. I've been using the simple Underwood pick-up from the beginning and I'm still happy with it," Trevor explains on his website.

At 1:23, you can guess that the amp that Trevor adjusts is an SM-900

"When I play with the Melvins or Fantomas I have an Ampeg SVT Pro-4 out in LA, or I'll just use whatever crap Buzz has lying around," says Trevor, on his website. And in this photo, two Ampeg SVT Pro-4s can be seen behind Trevor.
