The SX300R is a solid-state three-channel rack guitar preamp from Carvin's SX series, drawn in 2002. Two drive channels each have a dual-gang drive control, their own volume and active hi, mid and low controls on an op-amp signal path. The third, clean channel has its own clean level and its own hi, mid and low controls. A DSP effects section with level and select and adjust controls completes the front panel.
