Crate Amplifiers CR-160 is a versatile guitar amplifier that offers a wide range of tones and features to suit any player. With two channels, Normal and Overdrive, the CR-160 can produce anything from clean, shimmering tones to thick, saturated distortion. The Normal channel features a 3-band EQ with Bass, Mid, and Treble controls, while the Overdrive channel adds an additional Gain control for dialing in the perfect amount of distortion. A Bright switch on the Normal channel adds extra sparkle to your tone, while a Channel Selector switch lets you quickly switch between channels.
