ANALOG DESIGN
GETTING STARTED
The “air” boost is a gentle high frequency lift that begins around 10khz and gently
increases as it approaches 20kHz. The boost is inserted in the main signal path, at
the Triode gain stage.
Shaping tone
In addition to the harmonic and saturation control, the HG-2 also allows the user
to shape tone via the “tilt” selector and the “air” switch.
The “Sat. Freq.” selector
The 3 position “Sat. Freq.” selector is a simple yet powerful feature that allows the
user to choose what are present in the parallel saturation circuit.
In the “Flat” position, full bandwidth is fed into the circuit, allowing for
saturation of all frequencies.
In the ”Low” position, only the low mid and bass frequencies are fed into the
circuit. This allows the user to add body and weight to recordings.
In the ”High” position, only high mid and high frequencies are fed into the
circuit, allowing the user to add sizzle, presence and top end.
“Air” boost
The “Alt tube” selector switches between two sets of 12AX7 tubes in the parallel
saturation circuit. The “alt” tube is voiced slightly more aggressively, giving
the user a wider range of tones and saturation types. Both 12AX7 tubes can
be swapped for any 12AX7s for even more flexibility. The user can then switch
between them instantly.
