Fender Mustang LT50, User Manual

There are two ways to adjust an amp control knob setting. A control parameter that corresponds to an actual 

physical knob on the control panel can be adjusted simply by turning the physical control knob until the 

desired value is reached in the DISPLAY WINDOW. In the example below, the amp model’s TREBLE setting is 

adjusted by turning the physical TREBLE control knob on the control panel: 

 
Alternately, select a control parameter by turning and pressing the ENCODER; its surrounding box will turn 

from blue to red:

The control can then be adjusted by turning the ENCODER or by turning a corresponding physical control 

knob on the control panel:

At this point, press the ENCODER or the BACK utility button (

green arrow

) to accept the adjusted control val-

ues. Pressing BACK returns the user to the preset contents screen; pressing the ENCODER lets the user contin-

ue making controls setting changes, and the box surrounding the control setting will return to blue. When 

control setting edits are complete, press the SAVE utility button to save the changes to the preset.
