Tone Profile

A heavily distorted and vocal bass tone that functions as both a rhythm and lead instrument, characterized by a prominent midrange, aggressive pick attack, and expressive wah-filter sweeps.

Production Credits

Producer: Metallica; Flemming Rasmussen

Engineer: Flemming Rasmussen

Recorded at: Sweet Silence Studios (Copenhagen)

Signal Chain

Instrument: Aria Pro II SB-1000 Bass Guitar

Amp: Mesa/Boogie D-180 Head -> Mesa/Boogie 4x12" Cabinet (top) & 1x15" Cabinet (bottom)

Microphone: Electro-Voice RE20 (on 12" speaker cone) blended with a direct signal from the bass or amp's DI out.

Processing: Morley Power Wah Fuzz, Ibanez Tube Screamer TS9 (as a boost), dbx 160 Compressor (studio)

Other: Cliff famously used a bi-amp setup. The signal was split, with one signal running clean to one amp for low-end foundation, and the other signal running through the effects chain to a separate amp for the distortion and character.

Recording Notes

  • The core of the sound is the fuzz from the Morley pedal combined with the overdriven Mesa/Boogie tube amp.
  • A pick was used, and the playing style is aggressive, contributing significantly to the clanky attack and treble content.
  • The wah pedal was not just used for sweeping effects but was often 'parked' in a specific position to act as a powerful EQ filter, boosting certain midrange frequencies to help the bass cut through the dense guitar tracks.
  • The blend of a miked cabinet and a clean DI signal was crucial for maintaining low-end definition while allowing the top-end to be heavily distorted and processed.
  • The Aria Pro II's active electronics provided a strong, bright signal that was ideal for driving the effects pedals and amp head hard.

Recreation Tips

  • Start with a bass with active pickups if possible. Use a pick and play closer to the bridge for a brighter, more aggressive attack.
  • A key component is a vintage-style fuzz pedal (like a Big Muff or a dedicated Morley Fuzz Wah) placed before a wah pedal.
  • To simulate the bi-amp rig without two amps, use a pedal like a Boss LS-2 Line Selector or an EQ pedal with a blend knob. This allows you to mix your clean bass signal back in with the distorted signal to retain low-end clarity.
  • Boost the high-mids (around 800Hz - 2kHz) on your amp or an EQ pedal to achieve the signature 'clank' and presence.
  • For the melodic solo section, use the wah pedal for long, slow, and expressive sweeps to give the notes a vocal-like quality.
