Converts your clean tone into the powerful, saturated grit that you'd hear from a vintage, high-wattage tube amp. From classic crunch tones to tighter, more modern high-gain sounds. Three distinct distortion modes: LOCK (Organic): Natural distortion tone, like an overdriven vintage tube amp. STOCK (Tight): More modern, high-gain distortion, with tight low end and beefy mids. BARREL (Classic): Well-defined, vintage-sounding high-gain distortion.
