SIMULATOR for ELECTRIC Guitar

When using an electric guitar, select one of the settings nr, Jb, PE, Gt. These settings control the acoustic guitar simulator which makes an electric guitar sound like an acoustic guitar. Each setting gives a different sound character.

11 Editing Patches

The 504 comes with 24 predefined patches. However, the 504 offers many more possibilities for combining effects in innovative ways. To discover these possibilities, we recommend that you try changing the parameters (elements that make up patches) to create your own patches. This operation is called editing, and is done in the Edit mode.

To switch from normal Play mode to Edit mode, press
the EDIT key briefly (for less than 1 second).
* Note that if the EDIT key is held down for 1 second or
longer, the Bank Hold mode will be activated.

mode, the TYPE parameter cursor is flashing, and the

TYPE setting is shown on the display. This indicates that the TYPE parameter is currently selected for editing.

In Edit mode, the EDIT key or PATCH UP/DOWN pedals are used to select the parameter for editing. The 504 has the following parameters:

•TYPE: Selects the preamp module type. Make the selection according to the connected type of guitar and the desired application.

•LIMITER/EDGE: Depending on the setting of the TYPE parameter, this parameter enhances the edge of the guitar string sound or compresses the dynamic range.

•BODY & TOP: Emphasizes the lower frequency range (BODY) or upper frequency range (TOP), causing a voluminous sound or making the sound brighter and more distinct.

•AIR: Simulates sound as if captured with a microphone.

•MODULATION: Lends a soft expansive feeling to the sound, using a chorus effect. Depending on the parameter setting, an octave-higher component can be added, to emulate the sound of a 12-string guitar.

•REVERB & DELAY: Adjusts the reverberation effect. Depending on the parameter setting, a mix of delay and reverb can be created to increase the depth of the sound.

•De-AMP: Serves to control the frequency range that can be sonically unpleasant when reproducing the sound of an acoustic guitar over an electric guitar amplifier.

•F.B.SUPPRESSOR: Reduces feedback which can occur easily when using an acoustic guitar during a live performance.

•LEVEL: Adjusts the overall level of the patch.

Each push of the EDIT key moves the blinking parameter cursor indicator one step down. The TUNER indicator serves as parameter cursor for the LEVEL parameter. When the EDIT key is pressed while the lowest indicator (F.B.SUPPRESSOR) is flashing, the TUNER indicator starts flashing and the LEVEL parameter can be adjusted.

The parameter value is changed using the VALUE +/- keys. For details on parameters, please refer to section "12. Effect Parameters".

To terminate the Edit mode and return to the Play mode, press the EDIT key while the LEVEL parameter is selected (TUNER indicator is flashing). For information on how to store changed parameters, please refer to section "13. Storing Patches".

PRE AMP for ACOUSTIC Guitar

When using an acoustic guitar, select one of the settings na, Md, ry, br. These settings control the dedicated acoustic guitar preamplifier, each giving a different sound character. Choose the setting that is best matched to your playing style.

When one of the settings na, Md, ry, br (for acoustic guitar) is selected for the TYPE parameter, the LIMITER/EDGE parameter works as a limiter that compresses the dynamic range.

	stronger limiter effect (more narrow dynamic range).

The parameter creates a wide sound stage by adding a chorus effect.

Some settings result in a 12-string guitar sound.

HINT ! Selection of parameters to change

As described in 11. Editing Patches, parameters to be edited are selected by repeatedly pressing the EDIT key, but you can also use the patch pedals for this purpose.

Press the PATCH UP pedal (right patch pedal) to move the parameter cursor from the bottom up.

Press the PATCH DOWN pedal (left patch pedal) to move the parameter cursor from the top down.

HINT @ Switching parameters on and off

Except for LEVEL, any selected parameter can be turned on or off by pressing the PATCH UP/DOWN pedals simultaneously. The on/off condition can also be stored as part of the patch.

• To switch a parameter on or off:

When any parameter except LEVEL is selected in the Edit mode, pressing the PATCH UP/DOWN pedals simultaneously turns the parameter off. (The indication "oF" appears on the display.) The parameter can be

turned on again either by pressing the PATCH UP/DOWN pedals simultaneously once more, or by pressing one of the VALUE +/- keys. The parameter setting that was active before will be reestablished.

*When the F.B.SUPPRESSOR parameter is set to "SC", turning the parameter off and on again will cause the automatic feedback frequency detection to be performed once more. The frequency setting therefore may be different after the parameter is turned on again.

HINT # Parameter setting shortcuts

Normally, parameter values are set by tapping the VALUE + or VALUE – key once for each increment or decrement. For quick operation, you can use the shortcut function. This is activated in the Edit mode by pressing both VALUE keys together.

For example, if the LEVEL parameter is set to "20" and you want to change it to "29", you would have to press the VALUE + key 9 times. Instead, you can achieve the same effect by using the shortcut function: press the VALUE +/– keys together, which will change the value to "30" and then press the VALUE – key once to arrive at "29".

HINT $ Using the F.B.SUPPRESSOR

(1)Detecting feedback frequency automatically in Edit mode

Select a different setting for F.B.SUPPRESSOR and then select "SC", or turn the parameter off and then on again while "SC" is selected.

(2)Adjusting feedback frequency manually in Edit mode

If feedback attenuation in "SC" mode is not satisfactory, try setting the F.B.SUPPRESSOR parameter manually to a value between 1 and 30 to find the setting which yields optimum suppression.

(3)Detecting feedback frequency automatically in Play mode

In order to be able to automatically detect the feedback frequency while playing the guitar, you must first set the F.B.SUPPRESSOR parameter to "SC". In Play mode, you can then turn the parameter off and on again by pressing the foot switch FS01 twice. The feedback frequency will be detected automatically, and suppression will be active.

*During the detection interval (about one second), do not turn down the guitar volume or change other settings.

*If the F.B.SUPPRESSOR parameter is set to 1 - 30, switching the

parameter off and on again will not cause automatic feedback frequency detection.

*In either case, the F.B.SUPPRESSOR parameter setting will be stored when the currently selected patch is stored.

HINT % Master level adjustment

With the 504 you are also able to set the master level that governs the overall output level.

The master level is adjusted in Play mode. Hold the VALUE +/– keys down simultaneously for at least 1 second. The current master level will be displayed for 1 second.

While the level is being displayed, use the VALUE +/– keys to change it. The setting range is 0 –50. (Default value = 40)

The unit does not store the setting for the master level. Each time the power is turned on it has to be set again.
