The 100 Watt DSL 100 Dual Super Lead head features two footswitchable channels, Classic Gain / Channel A and Ultra Gain / Channel B. As the names imply, each channel has a very different character, with Classic Gain / Channel A taking you from a clean to crunch 1959 and then, via a mode switch, up to a 2203 style brute. Ultra Gain / Channel B takes you from a hot rodded 2203, via a mode switch, to a higher gain response with the addition of mid-boost. Each channel also has its own individual Reverb level.
