Trevor Dunn

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

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