M-107 
PHASE 100
DESCRIPTION
• Big brother of the Phase 90 with a broader range of sounds
• Four-position rotary switch selects four preset waveforms
• Spacey, psychedelic ambience for guitar solos or chords!
DIRECTIONS
To set up the Phase 100, rst plug your instrument into the Input jack and your amplier into 
the Output jack. Set the Speed knob to the middle (twelve o’clock) setting. Turn on the 
effect with the footswitch toggle, making sure the red LED is ON to indicate that the effect 
is active. Then switch between the four selectable waveform patterns with the Intensity 
knob. You’ll notice that some settings are much more subtle than others. After you choose 
the waveform that best suits the music you’re playing, adjust the Speed knob to the desired 
phase-shifting tempo.
For lead guitar, phase effects are most effective when they’re used sparingly. Playing “clean” 
through most of a tune, then popping it on for a solo, makes the effect especially noticeable by 
contrast. You can try adjusting the speed to synchronize with the tempo of the song, but most 
players nd that it’s more interesting let the phase effect have a unique tempo all its own.  
Experiment with tempos and see how they affect the emotional impact of your music.
For rhythm guitar, the Phase 100 works best with subtler intensity settings and slower speed 
rates, giving a mellow “undulating” character to chord strumming or arpeggios.
Phase 100’s are prized in the recording studio because of their high tone quality and reliable 
switching. One great studio trick is to record your track clean, then patch the Phase 100 
in between the clean, pre-recorded track and a new scratch track. You can then adjust 
the Speed knob in post-production, varying the rate for different parts of the song, and add 
interest and depth to the effect.
