ROAR Tubes – The Heartbeat of CHUCK
ROAR Tubes – The Heartbeat of CHUCK
An amplifier is only as good as its tubes. That's why we didn't choose any standard solution; instead, we developed our own ROAR tubes —specifically tuned for CHUCK, for maximum dynamics, harmonic warmth, and precise response.
While many modern amplifiers rely on sterile digital simulations, CHUCK's ROAR tubes deliver a true, vibrant tube sound. They operate at real high voltage , provide organic saturation, and let your tone breathe—whether you play lightly or with full throttle.
