Three output modes allow you to use this as a standard pedal, a line-level preamp, and a direct amp-sim using the built-in analog cabinet simulator. Use STANDARD mode with your normal guitar rig to totally transform your amp, or use PREAMP or CAB-SIM mode while recording directly into your audio interface. In each mode, the all-analog design and active EQ allow you to perfectly dial in the sound you need in any situation.
