The Westerlund Audio - ONE - Overdrive delivers a high-fidelity, studio-style preamp to your pedalboard that works great when pushed from preamp to overdriven territory. Loads of tone shaping options from the built-in 3-band EQ along with user-selectable clipping and transistor options. A Bright/Dark Tone Switch adds extra flexibility when paired with the EQ. A built-in adjustable boost can be added to your signal, great for when you need an extra bit of "umph" for stepping up to that solo. Touch sensitive and dynamic, this Westerlund One delivers some high-end tones to your rig.

From Westerlund:

With three unique modes (Clipping Off or "Amp Mode", Germanium 'GE' Clipping, and Silicon 'SI' Clipping), a gain boost, a 3-band EQ, and plenty of headroom, the ONE covers a wide range of sounds (from transparent to full on tube saturation) that enhance the musicality of your instrument and your unique playing.

Clipping Modes
The three unique FET based opamp gain stages and a FET tone recovery stage lend to a very tube-like tone and feel.

3-Band EQ
A musical and responsive EQ with treble, middle and bass control. The EQ helps dial in the ONE to perfection.

Tone Switch
The Bright/Dark switch gives additional tonal flexibility. "Bright mode" can be used for normal operation.

Adjustable Boost
The adjustable pre-gain boost is used in conjunction with the overdrive to go from a subtle volume increase to pushing your sound into amp-like saturation and compression.
