With these controls, you can enjoy full tone variation. 3. The JC-80 makes impressive, refined appearance, well integrated with functional design. Solidly built, all corners and edges are fiberglass reinforced and riveted. Chorus Effect Chorus effect of the JC series is produced through the use of special IC; which delays original signals; signals delayed have different pitches than the original ones. By mixing these signals, sound is produced in unison—that’s chorus effect. Thus sounds from an electric guitar are softened to give heavy sound never possible with conventional amps;ana “wide-spreading” effects. Terminals at Rear Panel Foot Switch Jacks .„.-® For Chorus/Vibrato Control On-Off control of Chorus effect or Vibrato effect can be done via foot switch when the switch is connected to this jack. (Controls one effect which is indicated by the Chorus/Vibrato Changeover Switch at front Panel.) ® For Reverb Control ! On-Off control of Reverb effect can be I done through foot switch. External Output Jack • Jacks for External Speakers By using 8-ohm external speaker system in combination with the built-in speakers, powerful volume output is obtained. - • Line Out Use this Line Out when connecting the JC-80 directly to PA mixer or when recording. FOOT SWITCH CHGRUS REVERB VIBRATO EXT. SPEAKER LINE OUT m 8 OHM Function of Controls • Input (High/Low) Two input sockeis are provided for suitable selection according to electric guitar output to be connected. In general, use “high” socket, but use “low” with electric guitars having large output. • Volume Control Controls volume. • Vibrato Speed Control Controls vibrato effect speed; turning the control clockwise increases the speed. ® Vibrato Depth Control Controls depth of vibrato effect; turning the control clockwise deepens the effect. ■ ® T rebie • • Middle Tone Controls • • Bass Tone controls for treble, middle and bass enable various tone settings. ® Distortion Control With this control, mild distortion sound is obtained; sounds produced by control setting are distorted without excessive tonal change.
