BCU Active Onboard Tone Expander Guitar Pot Upgrade
The Artec BCU (Band Control Unit) is a compact onboard tone-shaping tool that lets you dramatically transform your guitar or bass sound with just a twist of the knob. Whether you want rich, fat mids or a bright, cutting high-end, the BCU gives you a wide range of tones — from vintage Tele sparkle to thick humbucker growl — all from your existing pickups.
Unlike typical EQ circuits that can sound artificial or sterile, the BCU is designed to enhance and simulate the natural resonance of real pickups, making your tone feel organic and musical.
How it works:
– Knob at 0: Adds warmth and thickness — perfect for getting a humbucker-like tone from single coils.
– Knob at 5: Adds harmonic presence with a slight mid scoop.
– Knob at 10: Boosts both low and high frequencies for a bright, expressive tone with a "V" shaped EQ curve.
Features:
– Works with both electric guitars and basses
– Compatible with passive and active pickups
– Push-pull switch to activate the circuit (model BCU)
– Extremely low power usage — a single 9V battery can last for years
Perfect for players who want more versatility without changing pickups.
