Choose from Solid State (Silver), Tube (Gold) & Tape (Titanium) saturation with the Tone selector. Silver brings a clean style saturation, with Gold you get more grit and edge, and Titanium brings the Tape harmonics and punchy saturation to your audio. You can go from very subtle sounding to edgy,. Increase apparent loudness without raising peak levels, and make your sounds cut through in a mix, or add a nice warm glow. These 3 very distinct flavors give you plenty of tone control additionally with the “Input/Drive” control and the “Roof” control. Easy to dial in the sweet spot and details you want.
