Westerlund One Preamp

https://www.westerlundaudio.com/product/westerlund-one

Designed less like a traditional stompbox and more like a high-end studio preamp for your instrument, the Westerlund ONE treats your core tone as something to elevate rather than replace. Built around three unique FET-based op-amp gain stages and a FET tone recovery stage, it captures a remarkably authentic, tube-like feel with massive headroom and exceptional touch sensitivity.

The pedal’s versatility stems from a deeply configurable architecture:

  • Flexible Clipping Modes: A 3-way toggle lets you choose between Hard clipping, Soft clipping, or disengaging clipping entirely (“Amp Mode” for clean, transparent boosts), while a dedicated switch lets you select between Germanium or Silicon diodes to tailor the grit.
  • Pre-Gain Boost: An independent, adjustable boost circuit sits before the gain stage, making it easy to jump from a subtle volume lift straight into rich, amp-like saturation and compression.
  • Sculpted Tone Controls: Features a musical, responsive 3-band EQ (Bass, Middle, Treble) alongside a global Bright/Dark tone switch to help the pedal sit perfectly with any guitar or rig.

Whether you need a pristine, high-headroom line driver, a touch-sensitive overdrive, or a roaring preamp to punish the front end of your amp, the Westerlund ONE provides a polished, professional-grade foundation that honors your natural playing dynamics.
