One

Westerlund's debut pedal combines three FET-based opamp gain stages with a FET tone recovery stage for tube-like overdrive response. The circuit offers five clipping modes via dual switches—Hard/Soft and Germanium/Silicon—plus an 'Amp Mode' with clipping off for transparent preamp operation. Made in the USA, the ONE functions as a high-end preamp extension for guitar or bass. The pedal features a musical 3-band EQ (Bass, Middle, Treble), Bright/Dark core voicing switch, and separate Gain and Level controls. An adjustable pre-gain Boost (with dedicated footswitch) ranges from subtle volume lift to full amp-like saturation. The combination of clipping switches yields five distinct overdrive textures, from soft germanium compression to hard silicon grit. Built for versatile tone-shaping, the ONE moves from clean transparent boost through edge-of-breakup to full tube saturation, depending on clipping mode. The FET topology delivers dynamic touch response and compression similar to tube preamps, making it ideal
