TUBE AMP (TUBE pre-AMP)
The Tube Pre-Amp settings are made in this mode.
To locate this mode:
1. Press the [MENU/EXIT] button to display the MENU, select PAGE B by the [PAGE] button,
and then press the [1] TUBE AMP button.
2. Or, move [OVERDRIVE] knob pressing the [MENU/EXIT] button.
1. OVERDRIVE - EXPRESSION
This is for varying the Overdrive value by operating the Expression.
EX EX
EX EX EX-OD
-OD
-OD -OD -OD:
If you operate the Expression Pedal, the overdrive changes along with the volume.
OD OD
OD OD OD-EX
-EX
-EX -EX -EX:
The Expression affects only the volume and not the overdrive value.
2. OVERDRIVE - BIAS
This parameter finely adjusts the bias voltage of the tube 12AU7.
The setting range is -32 to +31.
3. OVERDRIVE - DRIVE
This is for adjusting the Overdrive Value.
The overdrive increases as the value increases.
This is linked with the [OVERDRIVE] knob on the volume panel.
4. BUFFER - TUBE AMP
This is for switching the buffer on/off by the tube 12AX7. All the signals of the Swell,
Great, Pedal pass through this circuit.
NOTE: If you are using the LINE OUT jack and the HEADPHONE jack, the Buffer Amp works only
on R (right).
5. BUFFER - BIAS
This parameter finely adjusts the bias voltage of the tube 12AX7.
The setting range is -32 to +31.
NOTE: The parameters in these modes are Preset Parameters and are recorded to each Combi-
nation Preset.
™ Please understand that the tone color or the depth of Overdrive varies from
organ to organ even if the parameter are the same, as the characteristic of
each tube is different.
USING THE EQUALIZER TOGETHER
If you distort the sound by overdrive or by changing
the bias, new harmonics are added. By using the
equalizer, a wider range of tones may be acquired.
BUFFER AMPLIFIER
A Buffer Amp changes the characteristics of the
sounds passed through it, without modifying the gain.
This organ uses a tube and a transformer in its buffer
amp.
