content than just the fundamental note which can create unwanted
pitch shift artifacts. Overtones, subharmonics and pitch variations when
playing chords will affect how “clean” the pitch shifting is. If you hear
strange artifacts when playing chords or a harsh sound when feeding an
overdriven/distorted signal to the pedal, it´s simply because the pedal
pitch shifts every frequency present in the signal. Hence, the cleaner
this signal is (frequency-wise and distortion-wise), the cleaner the pitch
shifting will be.
We recommend connecting the 8-ball directly to the instrument, or as
close as possible. This will make the effect more natural and pleasing to
the ear. Play simple chords or single note lines for best results.
HOW TO USE THE 8 BALL
Start by setting the mix knob to noon. This will give each octave roughly
the same volume as your dry signal when the controls are set to maxi-
mum. You can then adjust the octave controls to taste for each channel.
If you need more volume from one or more of the octave signals, turn
the mix knob up. This will bump up the octave volumes and attenu-
ate the dry signal at the same time, thereby keeping the overall output
more or less the same.
The trick is to play around with the levels by finding a good starting
point on the mix knob, then tweak each octave level to taste and com-
pensate on the mix knob, if needed.
Note: Although the algorithm is very precise and polyphonic, a signal
coming from an electric guitar/bass contains a lot more frequency
