Setting

Examples

To show you the immense potential of the Dr. Robert Unknown Pleasures Ltd. Edition, we recommend you trying the following setting 

examples. These examples do not show specific positions for the VOL and Disorder! Vol knobs as they will depend on the output of the 

guitar you use. The Dr. Robert Unknown Pleasures Ltd. Edition pedal is pretty loud at mid to high gain settings so we recommend you to 

start with both volume knobs at 9 o’clock and adjust them to match unity gain of the unit bypassed. This way you can make sure you’re 

not overloading the amp’s preamp and all the saturation comes from the Dr. Robert Unknown Pleasures Ltd. Edition.

These examples were fine-tuned with different guitars (mentioned on each diagram) and a Doctor Z Maz 18 amp.
