24 patches are available
The 24 patches can be easily selected by
pressing the patch pedals. The right patch
pedal switches to the next patch and the
left patch pedal switches to the previous
patch.
In the initial condition, the 504 is set up
so that the patch pedals select patches
continuously, but you can also set up the
unit so that patches are switched only
within a certain bank of four patches. [For
details, see section 9 Patch Switching
(Application: Bank Hold ON).]
Banks are selected with the VALUE +/-
keys. Press the VALUE+ key to select the
next bank, and the VALUE- key to select
the previous bank.
For example, to switch from Patch 2,
Bank A to Patch 3, Bank C, the patch
pedal would have to be pressed nine
times. Instead, you can press the
VALUE+ key twice to switch to Bank C,
and then press the patch pedal (UP) just
once to select Patch 3.
Using the Bypass (Mute)/Tuner Mode

In the Bypass mode, the effects of
the 504 are temporarily turned off,
so that the original sound of the
instrument only is heard. In this
mode, the auto-chromatic tuning
function is also active. It is also
possible to activate muting, to
prevent the tuning sound from
being sent to the output.
Press both
pedals together

reverts to the previously selected patch.
Tuner mode
The 504 is initially set so that the auto-chromatic tuning function for the guitar activates
automatically when the Bypass(Mute) mode is invoked. In Bypass(Mute) mode, pick an open
string to be tuned. The closest note will be shown on the display.

When the tuning function is active, the parameter cursor LEDs
serve as tuning meter, designed to enhance tuning precision
during fine adjustments.
Turning tuning function off
If you do not want to activate the tuning function in
Bypass(Mute) mode, press the STORE and EDIT keys
simultaneously for more than one second in Play mode. The
tuning function will be turned off, and this setting will be stored even when the power is turned
off. When you turn the function off, the display will show "tunEr oFF" (tuning function off).
To turn the tuning function on, press the same keys simultaneously again. The display will show
"tunEr on" (tuning function on).
NOTE: Please note that the tuning function may not operate properly if other effect modules between the
guitar and the 504 are on.
