Congratulations! You have just purchased the finest harmonic distortion-sustain device developed to date for the electric guitar player. The Big Muff Pi will give you a sweet violin-like sustaining sound. It’s the same legendary sound created by Jimi Hendrix.
VOLUME CONTROL-sets the output level.
SUSTAIN CONTROL- adjusts the amount of sustain and distortion.
TONE CONTROL-provides a range of sounds from high treble to deep bass.
-OPERATION AND WARNINGS-
Power from the internal 9-volt battery or external battery eliminator is activated by plugging into the input. The input cable should be removed when the unit is not in use to avoid running down the battery.
To achieve its long sustain, the Big Muff Pi has very high maximum gain. This requires that pickups and cables be well shielded and properly grounded to avoid excessive hum when high sustain control settings are used.
The small jack on the back of the Big Muff Pi is for a 9-volt battery eliminator capable of delivering 100 mA of current. The unit’s battery may be left in or taken out when the eliminator is in use.
