Fat Mike

In this picture you can see an Ampeg SVT Cabinet behind Fat Mike on stage

Fat Mike uses this pedal for play songs like "Medio-core" or "the decline" (intro)

From 0:00-0:04, a young Fat Mike can be seen jamming on an early model headless bass (no tremolo system). This is the only time I have seen him use this. He mostly uses Fender P basses, and a few other random models as backup.

On the second page of this website, I got the clue to which headless bass model it could be. The Hamer Slammer series headless bass is the one he uses in this video. The cutaways are to make it look more like a Steinberger headless, a popular model at the time. The picture I had to upload to add a new item, is a similar headless bass, I could not find any pictures of a similar Hamer Slammer headless he is using.

During this video, when performing onstage, at 0:40 there is a pretty good shot of it. Fat Mike is using a modified Fender P-bass. He used this throughout his time with NoFX, he also used a danelectro later as well as several other bass guitar models.

Throughout this live performance, fat mike can be seen using a P-bass style G&L.

He is holding/playing a Danelectro DC Cooper bass in his profile picture on EquipBOARD.
