that's it? i thought the ds-1 was for slight boosts and wouldn't get this gainy as a sole pre amp.

would it work with a fender?

DS-1 works fine with a strat with a humbucker, turn your mids all the way up on your amp treble 5-7, bass 5, Ds-1 distortion all the way as well as the level and the tone between 10 and noon

Going by this site , which is dedicated to Kurt's gear, this is what he had at the time of Bleach's recording:

Pedals:
Distortion: Boss DS-1 or Electro-Harmonix Big Muff Pi
Chorus: Electro-Harmonix Small Clone
Fuzz: Univox Superfuzz or Vox Tone Bender Fuzz
Don't know any of the settings, the site wasn't that detailed.

Amp:
Randall Commander Head
'68 Fender Twin

And of course, guitar:
Fender HSS

Hope that helps!
Gear:
Guitars: ESP/LTD EC-400, Ibanez GRX20, Washburn D-10 M/TWR
Amp: Peavey Vypyr 75
Pedals: Digitech Whammy, Boss DS-1, Boss CH-1, Sanpera I

YDG!?
