Fat Mike admits he plays a dano just due to it weighing nothing. He has a bad back.
Bingo. Punk
attitude. He makes what works for him work for his punk.
Also, I'm kinda tired of hearing the "cop the right 'tude, and it's whatever, mannnnn" response to this. It is to a certain extent, but bands that play SOLELY WITH ATTITUDE tend to sound like crap. TOTAL EAR BLASTING CRAP.
Wow. So ferocious with the all-caps.

You've got the 'tude going yourself there mannnnn.
So true that sarcasm really doesn't translate well on the Net; I was being facetious in my previous post to make my point. Quite frankly, I couldn't agree with you more. I'm sick of the phrase "Cop a 'Tude", "Dude" and all that similar BS as well.
But I'm also sick of gear being exalted to magic-bullet status. The real magic bullet is putting in the time to learn your instrument and making heartfelt music. Mike Watt uses what he uses. His bass got stolen, he changed to a different brand/make for that and a variety of other reasons. Doesn't matter what he uses, he's still playing from his heart.
Jean-Jacques Burnel would sound like himself no matter what he played, Brian Ritchie rocks the VF whether he's on an ABG or EBG... Well, the list goes on.
IMO Watt, Burnel, Simonon each play with their own inimitable
attitude, no matter what gear they use. Watt now endorses [Invalid or Expired Link Removed] amps. Nobody here suggested Eden yet, it's not "punk". Sifting through this thread the general consensus is punk requires a pick, P-bass and SVT.
So, my suggestion to you is the Tronographic Rusty Box, because my ideal tone for punk (and the one I actually use) just happens to be the same tone as Shellac, except with WAAAAY more mids.

Cool suggestion. What works for you may work for the OP, especially if he uses an Eden amp

. Gear. Yes, to an extent, but just as attitude will only get you so far when it isn't backed up by talent. Many great bass players (not just punk) got their start on home-made instruments or converted guitars -- that's punk attitude. Attitude and talent gets you further than a plethora of gear.
Anyone want to start an all acoustic punk jug band infused with dub reggae?? I'll play jug...
