The PRS Sonzera 20 Combo's two channels achieve a stunning array of tones. Bell-like chime? It's in there. Thick crunch. No problem. Heavy saturation? You got it. Sculpt each channel with independent tone controls. A global Presence knob dials in the perfect level of intensity. Inject your lead tone with a distinctive high-end snap via the Bright switch. A lush reverb adds dimension to your playing. Or use your own effects with the built-in effects loop. The PRS Sonzera 20 Combo is a solid gig- and studio-worthy guitar amplifier.
