Kim Thayil — £1,000 · Pro-Level Rig

• Alternative tunings are essential — Thayil rarely plays in standard tuning. Drop B (BGDGBE), open D, and drop C are his most common registers
• Open strings ringing against fretted notes is the signature dissonance — in "Black Hole Sun," the open low B creates a constant drone under the chord changes
• Less is more — Soundgarden guitar parts leave space. Count rests as carefully as notes
• The boss DS-1 settings are mid-way, not maxed — tone around 4-5, distortion around 5-6. It adds grit but doesn't eliminate the amp character
• Heavy pick gauge (.10s or heavier) for the low tunings — lighter strings feel like rubber bands in drop B
• The guitar body matters more than the amp channel — Les Paul into the Marshall's clean channel with DS-1 in front is very different from a Strat
• Feedback is a compositional element — "Superunknown" era Soundgarden uses feedback as melody in places like "Like Suicide"
• Listen to the bass first before learning guitar parts — in Soundgarden, the bass and guitar are often in different rhythmic layers, not locked together

• ✗Scooping mids on the JCM800 with humbuckers — the mid-forward character of British amps with humbuckers is the central sound of classic rock. A mid scoop removes the fundamental voice of the combination
• ✗Placing a tuner or buffered pedal before the fuzz pedal — most fuzz circuits (especially germanium ones) are sensitive to the impedance of the signal feeding them. A buffered pedal before the fuzz changes how the guitar volume knob responds. Run fuzz first in the chain
• ✗Setting the amp bass too high — the inherent warmth of mahogany means you need less bass EQ than with a Strat. Starting at 5 rather than 7 prevents low-end mud.
• ✗Using a high-gain distortion pedal instead of amp gain — British crunch amps have a specific harmonic character when driven from their own gain stage. A pedal changes this character.
• ✗Playing at bedroom volume expecting amp-driven tone — the power-tube saturation that defines this gain structure only occurs when the amp is working at substantial output. This is not replicable at low volumes.
• ✗Expecting consistent performance from a germanium fuzz in cold conditions — germanium transistors are temperature sensitive. The bias point shifts significantly in cold weather.
• ✗Keeping the gain on the fuzz at maximum all the time — rolling back the guitar volume on a Big Muff gives a cleaner, more dynamic tone for rhythm parts while keeping the pedal engaged.
• ✗Perfect production standards — grunge is intentionally rough and not always in tune. Striving for technical precision misses the emotional point of the genre.

Gibson Les Paul or SG into a Marshall head, often with a Boss DS-1 for additional gain. The key to Soundgarden's heaviness is the tuning — frequently in drop B, C, or open D — rather than pedal gain. Thayil uses open strings ringing against fretted notes to create the dissonant, droning quality of songs like "Black Hole Sun" and "Spoonman."
