To stop the rhythm, press the RHYTHM switch while the rhythm is playing. The rhythm will stop when you enter Bypass, Mute, or Edit modes. AUX IN Sound from an audio device (e.g. CD or MD) connected to the AUX IN jack can be mixed with the effect sound for listening, which is a convenient way to practice along with a song. The AUX input and the effect output will automatically be mixed and output from the OUT PUT jack except when you are in Phrase Trainer mode. Use the controls on your audio device to adjust the AUX IN volume. Expression pedal You can use the expression pedal to control 23 types of Pedal effect in realtime. If a program uses a Pedal effect, the pedal indicator LED’s will light to indicate the Min-Max value of the effect when you press up and down on the pedal. Operation for the SAMPLE1— LOOP2 pedal effects is different from the other effects (see p.14). Using the expression pedal as you play

1. In Program mode, select a program that uses the expression

2. Make sure that the pedal indicator is lit. If it is not lit, advance

the expression pedal once as far as it will go, making the top pedal indicator light (the pedal will be on)

3. Operate the expression pedal while playing your guitar. As

you raise and lower the pedal, the output sound will change correspondingly. If VOLUME is selected in the Pedal effect, it will not be possible to turn the expression pedal on/off. The pedal indicator will re- main lit. The on/off status of the expression pedal is not memorized by each program. Do not apply excessive force to the expression pedal. Before oper- ating the expression pedal, verify the amount of force that is re- quired to make the pedal indicator light and to apply the effect. Effect Select mode In this mode, you can press the DOWN switch to switch the drive channel while you perform. You can press the UP switch to turn the Modulation and Ambience effects on/off.

Phrase Trainer mode In this mode, you can record a phrase from an audio device (CD or MD) connected to the AUX IN jack, and play it back repeat- edly as a loop. Then you can practice a phrase on your guitar while playing to the repeating phrase. Since you can slow down the playback speed without affecting the pitch, this is a convenient way to learn or practice phrases from recordings that are difficult to play. In Phrase Trainer mode, the expression pedal will automatically function as the volume control of your guitar. When you enter this mode, the Modulation, Pedal, and Ambi- ence effects will automatically be turned off. (When you exit Phrase Trainer mode, the previous settings will be restored.)

Adjusting the expression pedal (Calibration) If you find the expression pedal difficult to use, perform this pro-cedure so that the pedal will function optimally. For example ifthe effect does not reach maximum when the pedal is advancedall the way, or does not reach minimum when the pedal is re-turned all the way, use the following procedure to make the ap-propriate adjustments.When making adjustments, use your hand to move the pedal.Accurate calibration may not be possible if you use your foot tooperate the pedal.1. Turn on the power while simultaneously holding down the EXIT switch and the PEDAL switch. The Multi-display will show “PEDAL” for approximately one second, and will then indicate “MIN.”2. Slowly return the pedal to the full back position. When it stops, release your hand and press the WRITE switch. The Multi- display will change from “MIN” to “MAX.” If you decide to halt the adjustment procedure, press the EXITswitch. The power-on display will appear, and you will enterProgram mode.3. Slowly advance the pedal. When it stops, release your handand press the WRITE switch.

The Multi-display will indicate “COMPLT” for approximately one second. Then the power-on display will appear, and you willenter Program mode.After the adjustment procedure has been completed, verify theoperation of the pedal.Select an effect that will make it easy to verify the adjustment.For example, set the Pedal effect to the VOLUME effect, set the value to 0, and check the MIN level when the pedal is returned all the way.If you make a mistake during the calibration procedure, the Multi-display will indicate “ ERROR ,” and you will return to the screenbefore the adjustment (the “ MIN ” display). If the “ ERROR ” dis-play appears for repeated attempts, a malfunction may have oc-curred. In this case, please contact your dealer. Restoring the user programs to the factory settings (Reload)

SLOWATK 0...10.0 0...10.0 — — Chorus and flanger are effects that delay the sound slightly to modulate the pitch, and combine the modulated sound with the original to produce a sensation of modulated spaciousness. The following parameters are assigned to each knob. Knob 1 TYPE Select the effect type Knob 2 SPEED/PITCH Adjusts the speed/ Adjusts the pitch Knob 3 DEPTH/FINE Adjusts the depth/ Adjusts the fine pitch Knob 4 FEEDBACK Adjust the strength of the tonal character. Knob 5 MIX Adjust the mix balance between the effect sound and the original sound CHORUS (Chorus) This chorus effect creates a sense of modulation, spaciousness, and vibrato by slightly delaying the sound, modulating its pitch, and combining it with the original sound. This is most effective when used in stereo. FLANGER (Flanger) This is a vintage flanger that produces modulation and a sense of pitch movement. PHASER (Phaser) This effect cyclically modifies the phase shift of the sound, and mixes the phase-shifted sound with the original sound to pro- duce modulation. TREMOLO (Tremolo) This effect adds depth to the sound by modulating the volume. PAN (Panpot) This effect cyclically changes the pan of sound, when stereo play- back is used. WAH UP (Auto-wah filter up) This is an auto-wah filter that automatically opens or closes ac- cording to how hard you pick the strings. WAH DWN (Auto-wah filter down) Auto wah in opposite direction from WAH UP PITCH (Pitch) This is a pitch shifter that can change the pitch in a +/-2 octave range. Intelligent Pitch Shifter MAJ3UP (3rd up in a major key) MAJ3DWN (3rd down in a major key) MIN3UP (3rd up in a minor key) MIN3DWN (3rd down in a minor key) 4TH (4th up in a major key) 5TH (5th up in a major key) MAJ6TH (6th up in a major key) The Intelligent Pitch Shifter creates musically useful harmonies by varying the amount of pitch shift according to the note you play and the key in which you are playing. For example if you select a pitch shift of a 3rd upward in a major key (MAJ3UP), the amount of pitch shift will vary automatically between three semitones (a minor third) and four semitones (a major third).

• When MAJ3UP is used with a key setting of C The pitch created by the intelligent pitch shifter is shown in parentheses ( ). If your instrument is not tuned correctly, the results may not be as you expect. In this case, re-tune your instrument. The intelligent pitch shifter will function when you play indi- vidual notes. It cannot produce the effect for chords. This effect cannot be used simultaneously with a Pedal effect (ex- cept for VOLUME) or with the ROOM1—ARENA Ambience effects. If you use the Intelligent Pitch Shifter in a program in which the Pedal effect or a ROOM1—ARENA Ambience effect is turned on, the pedal or ROOM1—ARENA Ambience effect will be turned off automatically. SLOWATK (Slow Attack) This effect gradually raises the volume each time you pick your guitar. Value knob 2 controls the speed of the attack, and value knob 3 controls the threshold level. As you raise the threshold level, you will need to pick more harder to produce the slow attack effect.14 ○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○

If you use this effect in a program where the Modu- lation effect is turned on, the Modulation effect will automati- cally be turned off. F BACK 1 and 2 cannot be used simultaneously with the ROOM1—ARENA Ambience effects. If you use these effects in a program where ROOM1—ARENA are turned on, the ROOM1—ARENA effect will be turned off automatically. DELAY—HALL cannot be used simultaneously with the Ambi- ence effect. If you use this effect in a program where the Ambi- ence effect is turned on, the Ambience effect will automatically be turned off. SAMPLE1—LOOP2 cannot be used simultaneously with a Modulation effect or Ambience effect. If you use the SAMPLE1— LOOP2 effects in a program where a Modulation effect or Am- bience effect are turned on, that effect will be turned off auto- matically. VOLUME (Volume) This is a volume pedal. Value knob 5 sets the minimum level. CHO1 (Chorus1) This is a chorus effect in which the pedal controls the depth of the pitch modulation. CHO2 (Chorus2) This is a chorus effect in which the pedal controls the speed of the pitch modulation. VIBRATO (Vibrato) This is a vibrato effect in which the pedal controls the speed of the pitch modulation. FLANGER (Flanger) This is a flanger in which the pedal controls the bandwidth (modulation) of the effect. PHASER (Phaser) This is a phaser in which the pedal controls the speed of the phase modulation. TREMOLO (Tremolo) This is a tremolo effect in which the pedal controls the speed of the volume change. PAN (Panpot) This is a pan effect in which the pedal controls the speed at which the position of the sound will change when stereo playback is used. WAH (Wah) This is a wah in which the pedal controls the peak frequency. FILTER (Resonance Filter) This is a resonance filter in which the pedal controls the peak frequency of the filter. RING (Ring Modulator) This effect creates a bell-like sound in which the pedal controls the pitch. To obtain the cleanest effect, use the pickup closes to the neck, turn down the tone of your guitar, and play near the 12th fret. PITCH (pitch shifter) The pedal will control the amount of pitch shift. When value knob 5 is at "0" only the original sound will be heard. At "5" the original sound and effect sound will be mixed equally, and at "10" only the effect sound will be heard. Feed Back In this effect, the pedal controls the vibrato that is applied to the feedback sound. While sustaining a note on your guitar, advance the pedal to pro- duce a feedback sound. The feedback sound will disappear when you return the pedal. Value knob 3 adjusts the speed of the vi- brato. There will be no feedback effect if OFF, ACOUSTIC, or CLAS- SIC COMP is selected for the Drive Amp effect. F BACK1 (Feed Back1) A feedback sound will be generated to the pitch of your play- ing. F BACK2 (Feed Back2) A feedback sound will be generated one octave above your playing. DELAY (Delay) In this effect, you can use the pedal to control the input level of the delay. By pressing the TAP switch two times, you can set the TIME of knob 2 to the corresponding tempo. ECHO (Echo) This is a echo in which the pedal controls the delay time. As on a tape echo unit, changing the delay time will also change the pitch. Value knob 3 adjusts the maximum delay time.15 ○ ○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○ p. 10
