This range corresponds to -12dB to +12dB in 1dB steps.
Turns off the LOW EQ band.
LO MID
This EQ band is a parametric band at 700Hz with a Q of 1.5. This type of EQ
works by boosting or cutting at 700Hz, along with a band of frequencies above
and below 700Hz. Q determines the range of frequencies affected (the
bandwidth). A Q value of 1.5 is an optimal setting for most EQ applications.
This range corresponds to -12dB to +12dB in 1dB steps.
Turns off the LO MID EQ band.
HI MID
This band is a parametric band at 2.5kHz with a Q of 1.5.
This range corresponds to -12dB to +12dB in 1dB steps.
Turns off the HI MID EQ band.
HIGH
This is a single-pole high shelf filter at 5kHz. This works by allowing you to
boost or cut the 5kHz frequency, along with all of the frequencies above that.
Use the HIGH band to control the highest frequencies in your guitar signal.
This range corresponds to -12dB to +12dB in 1dB steps.
Turns off the HIGH EQ band.
EDGE
This is a filtered limiter that gives your acoustic guitar a bright, edgy sound. This
effect works by taking the original signal, filtering out all frequencies that fall
below 2kHz, feeding that into a limiter and then mixing it back with the original,
unfiltered, unlimited sound.
Increasing amounts of edge.
Turns off EDGE.
