Breed by Nirvana — Amp Settings & Guitar Tone

Reference tone dialed on a Squier Classic Vibe Stratocaster into a Fender Mustang LT25. Settings below are cited from real sources; open the page in a browser for the interactive version, or get this tone dialed for your exact gear.

To recreate the aggressive grunge tone of 'Breed,' we'll use the Fender Mustang LT25's 'METAL LEAD' preset to capture the high-gain, mid-forward character. The Squier Classic Vibe '60s Stratocaster will stand in for the Mustang, with its single-coil pickups approximating the raw edge of Cobain's sound. This setup will emulate the saturated tube crunch and articulate picking response heard on the record.

What Nirvana actually used

Kurt Cobain's setup for recording 'Breed' on Nirvana's 'Nevermind' album featured his Fender Mustang guitar through a Boss DS-1 Distortion pedal into a Mesa/Boogie Studio Preamp, powered by a Crown Power Base 2 amplifier, and output through Marshall 4x12 cabinets. This configuration contributed to the song's aggressive tone. The recording took place at Sound City Studios in Van Nuys, California, with producer Butch Vig.
