GX-212 Amplifier Congratulations! You are now the proud owner of the Crate GX-212 guitar amplifier. These rugged amplifiers deliver serious clean and distorted sounds through two premium 12” Crate Custom speakers. Channel selection, Crate’s exclusive Shape circuit, and DSP on/off are controllable by the supplied three-button footswitch. An insert jack allows virtually noise-free connection of your favorite effects.
GX-212 Amplifier 1: INPUT: Connect your guitar here by means of a shielded instrument cable. OVERDRIVE CHANNEL: A high gain channel giving you sounds from a slight edge to serious overdrive. 2: GAIN 1: Gain 1 is active only when the Gain Select switch (#5) is out. When active, this control adjusts the amount of compression and distortion from the amplifier. At far left, the sound will have a thick compressed quality. As you turn the control to the right the amount of distortion increases.
GX-212 Amplifier 16: EXT. SPEAKER: Use this jack to connect an extension speaker cabinet to the amplifier. This jack is wired in series with the internal speaker(s). WARNING: Do not attempt to use headphones in the Speaker jack! Permanent hearing damage could result! 17: POWER ON LED: This LED illuminates when the amplifier is turned on. Connecting to the Insert jack: The Insert jack (#15) lets you patch external effects into the amplifier just prior to its power amp stage.
