- Boss DS-2 Turbo Distortion - standard Boss pedal casing and three knob configuration (level, tone, distortion), with the added bonus of a turbo knob. Set the tone and distortion knobs near the maximum, and turn the turbo knob to "II" to zone in on Cobain's tone. Used DS-2 pedals are readily available on Ebay.com and craigslist.com for about $50.00. New pedals go for $90.00 (presently as low as $40.00 at Musicians Friend). While the DS-2 distortion is known to have been a mainstay of Cobain's pedalboard (look closely at the photographs in the In Utero liner notes), also consider buying the Electro-Harmonix Big Muff pedal which provides dirtier distortion at lower volumes;
- Electro-Harmonix SmallClone - a must-buy pedal if you're planning on playing "Smells Like Teen Spirit" or "Come as You Are" for an audience of more than three people (your parents and significant other excluded). Set the rate knob at the 3 o'clock position and slide the depth switch down to experience the rapid, yet deep, chorus preferred by Kurt Cobain. If you're lucky, you'll find a vintage version of this pedal on Ebay.com, but not for less than $150.00. Vintage SmallClone's are widely considered to be more expressive, but are less reliable than the re-issue pedals from Electro-Harmonix. Also, vintage SmallClones surviving the Punk, post-Punk, and New Wave eras smell awful (and certainly nothing like teen spirit).
