Linking Effects
The patches of the 504 II consist of ten effect parameters (including two global parameters). By setting these parameters to the desired values, you can control the sound of a patch.
It is also possible to switch individual parameters on and off, and to program the expression pedal to adjust the value of a specific parameter.

The parameters TYPE, LIMIT/EDGE, LOW/BODY, HIGH/TOP have separate settings for acoustic and for electric guitar. Depending on

DELAY&REVERB
Mixes a delayed component and reverb component to the original sound, producing a feeling of depth and ambience.
DELAY+REVERB
is an effect which combines delay (delay time 210 mS) and
. Higher values result in deeper reverb effect and higher delay sound mixing ratio.

Allows using the expression pedal (FP01/FP02) connected to the CONTROL IN jack to adjust the delay sound mixing balance (reverb depth is fixed).

Expression pedal
A pedal icon ( 
) in the listing indicates that the parameter can be controlled with the expression pedal (FP01/FP02) when the value is selected.
If there is no parameter marked with a pedal icon selected in the entire patch, the expression pedal operates as a volume pedal.
Parameter on/off
Except for the TYPE parameter,
all parameters have an "
" setting which disables the parameter. (The effect is the same as when both [ 
]/[ 
] foot switches are pressed together in edit mode.)

De-AMP
This parameter serves for attenuating frequency bands that can sound harsh when an acoustic guitar is reproduced via a guitar amplifier. Choose the BRIGHT COMBO, COMBO, or STACK
