DescriptionStompbox
An auto-wah (filter) effect. Sensitivity sets a threshold which
determines how the filter responds to incoming signal levels. Cutoff
sets the center frequency for the filter. The BP/LP switch enables
either a bandpass or lowpass filter circuit. Signal frequencies just
above and below the cutoff point are filtered when the BP switch
position is chosen. When the LP switch position is active, only signals
below the cutoff point are allowed through the filter. The Hi/Lo
switch chooses one of two preset (filter) resonance settings. The
Up/Down switch activates a positive or negative modulation
direction (the “wah” filtering occurs above or below the source
signal frequency).
Auto-Funk
A funky wah effect, straight from 1970’s TV police show soundtracks.
You control it by dragging the pedal.
Classic Wah
A more aggressive wah effect. You control it by dragging the pedal.
Mode enables you to choose from the following: Retro Wah, Modern
Wah, Opto Wah 1, Opto Wah 2, Volume. Each has a different tonal
quality. The Q knob determines the resonant characteristics. Low Q
values affect a wider frequency range, resulting in softer resonances.
High Q values affect a narrower frequency range, resulting in more
pronounced emphasis.
Modern Wah
Dynamics Pedals
This section describes the dynamics pedals.
DescriptionStompbox
A simple compressor. Sustain sets the threshold level. Signals above
this are reduced in level. Level determines the output gain. The
Attack switch can be set to Fast for signals with fast attack transients,
such as drums, or to Slow for signals with slow attack phases, such
as strings.
Squash Compressor
Utility Pedals
This section describes the parameters of the Mixer and Splitter pedals.
DescriptionStompbox
A utility that is used to control the level relationship between Bus A
and Bus B signals. It can be inserted anywhere in the signal chain,
but is typically used at the end of the chain (at the extreme right
of the Pedal area). See Using Pedalboard’s Routing Area for details
on use. The A/Mix/B switch solos the “A” signal, mixes the “A” and
“B” signals, or solos the “B” signal. The level setting of the Mix fader
is relevant for all A/Mix/B switch positions.
In stereo instances, the Mixer utility also provides discrete Pan
controls for each bus.
