01Boss DS-1 Distortion (RECOMMENDED — not currently owned)

RECOMMENDED — essential for this tone. The DS-1 was Kurt's primary dirt source on Bleach. Run into amp's clean channel if you acquire one, then drop amp gain to 2-3.

Why these settings

Your Joyo DC-15 is a solid-state practice amp with a Marshall-voiced overdrive channel — more midrange bite than the original Fender Twin, which was used clean as a pedal platform. Without a DS-1, I'm pushing the amp's overdrive channel harder (gain 7) to approximate the grinding distortion. Roll treble back slightly (7 vs Kurt's reported 8) because the Joyo's solid-state clipping gets fizzy. Your GRG170DX humbuckers are hotter than Kurt's single-coil Mustang pickups, so the gain translates well. Tune to Drop C if possible — that's half this tone's identity.

PRO TIPKurt's right-hand attack was critical — he dug in hard with downstrokes on the low strings, letting notes bloom into controlled feedback. On a small amp, get closer to the speaker (2-3 feet) and let the guitar feed back naturally on sustained notes. The DS-1 is a $50 pedal and non-negotiable for authentic Bleach tones.
