INPUT –
Pedal input, nominally instrument level but can accept line level as well. When operating at line level, greater headroom is available with a 12V, 15V or 18V
power supply. Input impedance is 1M ohm.
POWER JACK -
This pedal contains circuitry that auto-detects both the voltage and polarity of the attached power supply. The pedal will function properly from 9V to
18V, center positive or center negative polarity. With very high output basses and line level signals, you may notice more input headroom with 12V or higher power
supplies. Be sure to use a low noise pedal type power supply, general purpose power supplies can introduce noise into the signal path.
OUTPUT –
Pedal output,
nominally instrument level but can output up to line level. When operating at line level, greater headroom is available with a 12V, 15V or
18V power supply. Output impedance is 1k ohm.
THEORY –
This pedal is designed as an essential tool for tone shaping and in reality, it is two complete pedals in one integrated fully foot-switchable package. Each
section contains a different type of filter, HIGH PASS/LOW PASS filters and 5 BAND EQ (bandpass boost/cut) filters. These filters can be used to fine tune a player’s
tone.
FILTERS -
The HIGHPASS filter is used to limit the low frequency extension of the signal and the LOW PASS filter is used to limit the high frequency extension of the
signal. This allows the low and high frequency content to be eliminated without affecting the rest of the spectrum.
5 BAND EQ –
The EQ section allows individual frequency bands to be boost or cut, for fine tuning of the tones within the extended midrange of most instruments.
Generally, a little EQ goes a long way depending on the player’s goals. The output trim can be used to either normalize the output (compensating for eq boost/cut to
maintain the same overall volume, or can be used to include an additional boost/cut when the EQ section is switched in.
