GT -80D QuadraDrive tm GT -80D QuadraDrive tm 3 ABOUT THE GT -80D: The Crate GT -80D QuadraDrive tm with Digital Sound Processing is truly unique and versatile, offer- ing you more performance and flexibility than any other compact amplifier . Start with two completely separate preamp stages: Solid State and Tube .
GT -80D QuadraDrive tm 4 1: INPUT : Connect your guitar here using a shielded instrument cable. OVERDRIVE Gains: 2: TUBE GAIN: This serves as the gain control for the Overdrive Channel’ s T ube preamp section, giving you con- trol over the compression and overdrive characteristics of the GT -80DSP’s input tubes.
GT -80D QuadraDrive tm 5 9: CLEAN LED: This LED glows green when the Clean Channel is chosen, and along with LED #19, gives you a visual sign that the Clean gains, tone controls and volume control are active. 10: SOLID ST A TE GAIN: This serves as the gain control for the Clean Channel’s Solid State preamp section.
GT -80D QuadraDrive tm 6 18: HIGH: Adjust the Clean Channel’s high frequency output with this control: in the center position the high fre- quency output will be “flat” (no boost or cut). T urning the control to the left reduces the high frequency output; turn- ing it to the right increases the high frequency output.
26: POWER CORD: Firmly plug the supplied, heavy-duty grounded power cord into this receptacle. When in use, be sure this cord is properly plugged into a safely-wired, grounded 120 volt, 60 cycle AC power outlet.
