Tap Tempo Key (31)
This key allows you to enter the tempo for the drum machine by tapping 1/4 notes. As the effects are beat-synced to the drum
machine, this also sets the tempo of the effects. The drums do not need to be playing for the effects to lock to the tempo.
This key has another special function: It enables a simple intro or ending to the drumbeat. To hear a simple intro of four 1/4 note
hi-hats before the drumbeat starts, press Tap Tempo before pressing Start/Stop. If the drumbeat is playing, press Tap Tempo before
pressing Start/Stop to automatically stop the drumbeat playing at the exact beginning of the next measure.
Amp Key (22)
Pressing the Amp key brings up the four AMP menus in the LCD; AMP, AMP DRIVE, AMP BASS and AMP TREBLE. The rotary control
under each menu parameter in the LCD allows you to change the parameter value. Holding the Amp key down for one half second
will turn the amp effect off and "AMP OFF" will be displayed in the LCD. Holding the Amp key down for another half second will turn
the amp effect back on, and "AMP OFF" will disappear from the LCD display.
FX Key (24)
Pressing the FX key brings up the four Effects menus in the LCD; EFFECT, FX SPEED or FX FREQUENCY, FX DEPTH or FX KEY and
FX WET/DRY. The rotary control under each menu parameter in the LCD allows you to change the parameter value. Holding the
FX key down for 1/2 second will turn the effect off and "FX OFF" will display in the LCD. Holding the FX key down for another half
second will turn the effect back on, and FX OFF will disappear from the LCD display.
Compare (press Amp [22] and FX [24] simultaneously)
If both the Amp and FX keys are pressed simultaneously, the Compare function is activated and "COMPARE" will be displayed in the
LCD. During this time, any edits to the preset are removed, permitting you to compare your changes to the original, unedited preset.
Press the Amp and FX keys simultaneously again to exit the Compare function.
Delay Key (26)
Pressing the Delay key brings up the four Delay menus in the LCD; DELAY TIME, DELAY REPEATS, DELAY VOLUME and DRUMS TO
DELAY. The rotary control under each menu parameter in the LCD allows you to change the parameter value. Holding the Delay
key down for one half second will turn the delay effect off and "DLY OFF" will display in the LCD. Holding the Delay key down for
another half second will turn the delay effect back on. "DLY OFF" will disappear from the LCD display.
Utility Key (28)
Pressing the Utility key brings up the four Utility menus in the LCD; PRESET VOLUME, GUITAR/DRUMS BALANCE, EXPRESSION
PEDAL and TEMPO. The rotary control under each menu parameter in the LCD allows you to change the parameter value. When
both the Delay and Utility keys are quickly pressed simultaneously, the Tuner function is activated. "TUNER" will be displayed on the
LCD along with the note value of the currently played string. Press any key to exit the Tuner function and "TUNER" will disappear
from the LCD display.
Tuner (press Delay [26] and Utility [28] simultaneously)
If both the Delay and Utility keys are pressed simultaneously, the Tuner function is activated and "TUNER" will be displayed in the
LCD. When the Tuner is active the display will tell you if the notes you're playing are in standard guitar tuning. See the section entitled
"Tuner Function" for more information.
Start/Stop Key (32)
Pressing this key will start and stop the drum machine. When in Play mode, the tempo LED will blink 1/4 notes at the current tempo.
When in Stop mode, the LED will be unlit. To hear a simple intro of four 1⁄4-note hi-hats before the drumbeat starts, press Tap Tempo
before pressing Start/Stop. If the drumbeat is playing, press Tap Tempo before pressing Start/Stop to automatically stop the drumbeat
playing at the exact beginning of the next measure.
Rotary Controls (13)
These are used to change the parameter values and also used to name presets. When a parameter value has been changed, "EDIT"
will be displayed in the LCD display and "PARAMETER" will be displayed. This is a reminder that you must store any changes to keep
them. If the changes are not stored and another preset is loaded, the previous preset will revert to its stored settings.
LCD Display (33)
All presets, parameters and values are displayed in the LCD.
Mic Input Control
The Mic Input knob (17) boosts the level of the mic input signal. The green Signal LED (21) will light when a detectable threshold
input level is reached. The red Clip LED (20) will light if the input signal is too hot. The best input signal level is achieved when the
green LED is solid and the red LED only blinks occasionally. This input mixes into the other audio outputs so when not using the mic
input, turn this knob down to minimize any noise.
