compressed and the envelope follower is not as responsive to the
dynamics of your playing. It is perfectly OK to use the FreqBox with the
Drive control all the way up.
Output Level: The Output Level control is used for balancing the
loudness of the signal when the effect is active with the loudness of the
signal when the effect is bypassed. When first setting up to play, adjust
the drive level first for optimum drive signal level, then adjust the output
level so it is balanced with the bypass signal. The Output Level control
has a wide enough range to boost the volume significantly - especially
with the drive control turned up all the way. Use caution with this
control for both your speakers and your ears! The Maximum output
level is much greater than your typical stompbox so watch out!!!
Freq: The Freq control is used to adjust the frequency of the VCO.
If the Envelope Amount and FM amount controls are all the way
counterclockwise, and the Sync is OFF, the Frequency of the VCO is
nominally 25Hz if it is fully counterclockwise. When it is fully clockwise
the frequency of the VCO is nominally 1.6KHz, or 6 octaves higher.
Wave: The Wave control is used to set the waveform of the VCO.
The legend around the control indicates approximately the locations
of the waveforms. The basic waveforms are: triangle, sawtooth,
square, and pulse. A triangle wave is produced when the control is fully
counterclockwise. As the control is advanced clockwise, the waveform is
crossfaded to a sawtooth, then to a square wave, then to a pulse wave.
Sync On/Off: The Sync On/Off switch engages the FreqBox’s hard sync
function, causing the VCO to be retriggered by the input signal. If the
input signal has a simple waveform, then the VCO will be retriggered
at the frequency of the signal. A very complex signal (like a dissonant
chord) will cause less predictable results, as the VCO will be retriggered
not at a predictable frequency but by the sum of all the frequencies.
A pitched tone may or may not be the result. With guitars, if a note is
plucked hard and left to ring, there are times when the second harmonic
is louder than the fundamental. You may hear this as the VCO tone will
shift with this change. If the VCO frequency is much lower than the
input signal, it is possible that you won’t be able to hear any output from
the VCO, especially if the waveform is a square wave, or pulse wave.
Env. Amount: The Env. Amount control sets the amount that the
