CONTROL PANEL FEATURES CONTINUED

5. Depth Control: This 6-position rotary switch selects the output tube’s low-frequency roll-o point. Set fully clockwise for the deepest low-

frequency extension. Lower settings (counterclockwise) expose more midrange texture and detail; the lowest settings emphasize more pres-

ence and bite. The three clockwise settings are voiced for single-coil pickups, and the three counterclockwise settings are voiced for humbuck-

ing pickups.

6. Texture Switch: This 3-position rocker switch selects the output’s high-frequency roll-o point. The middle position provides maximum

top-end extension and the most harmonically complex texture; the left position provides subtle high-frequency roll-o for a slightly smoother

texture; the right position rolls-o more high frequencies for the smoothest texture.

7. Send Level: A pedal-friendly low-impedance tube-buered eects send level control. Normal settings are between half and fully clockwise.

8. Return Level: A pedal-friendly high-impedance tube input eects return. Normal settings are between half and fully clockwise.

9. Tone Control: This control adjusts the balance of the high and low frequencies.

10. Volume Control: Turning this knob clockwise increases the preamp drive and overall sound level.

11. Pull Boost: Pull this knob to partially bypass the internal tone shaping/voicing circuitry, which boosts the preamp gain and increases the

midrange emphasis. This feature can also be accessed by the footswitch.

NOTE: THE BOOST FOOTSWITCH WILL ONLY FUNCTION WHEN THE VOLUME KNOB IS IN THE PULLED POSITION.

12. Input: Pedal-friendly tube input, 1 megohm input impedance.
