Johnson Amplification JM60 - Manual (Page 16)

Adjusting the Gate Threshold
1. Press and hold the Model button of the currently active modeling group. The numeric display will momentarily show “
”, followed by
the current threshold numeric value.
2. Turning the Select knob will change the gate threshold value. The threshold is adjustable from 1 to 30, and A1-A6. Higher threshold
values require stronger signals to open the gate. A1-A6 are auto swell gates. A1 through A3 are low threshold with varying times, and A4
through A6 are high threshold with varying times. Using these creates an automatic volume pedal type attack of the signal.
3. Press the same Model button again to exit the gate threshold edit mode.
Note: The gate threshold adjustments that are made must be stored to each preset. See page 16 for more on storing a
preset.
Editing Effects
The Marquis JM60/JM120 offer several effects to help complete your sound. There are three different groups of effects in the Marquis. You
can use one modulation/pitch shifting effect, one delay effect, and one reverb effect at the same time. You have the choice of 6 different
modulation or pitch shifting effects on the JM60 and 9 on the JM120, 3 different delays, and 3 different reverbs.
Selecting Effects
When a preset is selected on the JM60/JM120, the effects that are active in the preset will be indicated by the LEDs for each effect group.
Each of the three effects may be bypassed by pressing and holding down the Select button corresponding to the effect group that you wish to
bypass. Likewise, if an effect group is bypassed, you may engage that effect group by pressing the Select button once. Each successive press
of the button will advance through all effect types available within that effect group.
JM60 Mod/Pitch Effects Group
The Mod/Pitch effects group in the JM60 includes Chorus, Flanger, Phaser, Tremolo, Vibrato and Pitch Shifting. Only one of these effects can
be used at a time. To select an effect from the Mod/Pitch group, press the Mod/Pitch Select button until the LED next to the desired effect
lights up. The effect indicated is now active. The Mod/Pitch effects may be bypassed by pressing an holding the Mod/Pitch Select button
down. To disengage bypass, simply press the Select button again. All of the Mod/Pitch effects have three parameters that may be edited. The
level of the Mod/Pitch effects can be adjusted by pressing and holding the Mod/Pitch Select button down, and then using the Select knob to
increase or decrease the effect level. The following is a description of each of the Mod/Pitch effects and the available parameters:
