Crazy Tube Circuits Constellation OC41

A Star Map of Classic Fuzz

Meet the Constellation—a multi-mode Germanium fuzz and booster that’s like having a vintage fuzz museum at your feet. Inspired by the golden era of British fuzz circuits, this all-analog beast is built around hand-selected NOS black glass Germanium transistors for that warm, complex tone and silky clean-up we all chase.

Each pedal gets three carefully matched OC41s, giving you beautifully consistent tone and feel. The white-and-cyan print version brings a more balanced EQ response—rich but never muddy, bright without the bite.

And here’s where it really shines: a smart internal switching system gives you six distinct voices, pulling from some of the most iconic fuzz circuits ever made—plus a few surprises.

• FF – Classic Fuzz Face tones: round, wooly, and full of soul.

• VTB – Think Vox Tone Bender: brighter, tighter, and refined.

• 3/2 – A darker, moodier take on the Fuzz Face via the Tone Bender Mk1.5.

• 2 – Wild and saturated MkII flavor with sustain for days.

• RM – The Dallas Rangemaster-inspired treble booster: sharpens the highs, pushes your amp.

• RMFF – Treble booster into fuzz? Yes please. Bright, aggressive, and perfect for cutting through the mix.

Whether you want vintage-style grit, massive sustain, or a razor-edged lead tone that slices through a wall of sound, Constellation has a voice for it—and the Germanium warmth to keep it musical.
