SECTION 2 - PROGRAMMING THE ACOUSTIC ONE

Navigating The Acoustic One

The Acoustic One is designed to be both easy to program and flexible.
The structure of an Acoustic One program is logical, and  doesn't
require a lot of time to master.  

To select Programs in the Acoustic One:

1) After you power up, use the Data wheel to scroll through the

Programs. As you scroll, the effect group and footswitch LEDs
turn on and off. These LEDs indicate which effects are used in
each Program, and which Program in the Bank is selected.

There are 12 effect groupings printed on the front panel of the
Acoustic One. Seven are digital effect groups (delay, reverb, etc.) , and
five cover the preamp section (compression, gate, and EQ). Each
group has its own LED that indicates the status of each group.  

If the Status LED is lit continuously, an effect in the indicated group is
active. If the LED is not lit, no effects in the group are active. If the LED
is flashing, edit mode is active, and effects in the group can be select-
ed using the Data wheel.

Directly below each vertical group are the Effect Selector buttons.
These buttons allow you to select and/or bypass effects in the Acoustic
One. The following will happen when you use the Effect Selector but-
tons:

• When you select a bypassed effect, its group LED begins flashing

and the display shows a double dash (- -), indicating that the
effect is selected, but is currently bypassed. (Pressing the Select
button again activates the effect.)

• When you select an active effect, its group LED begins flashing

and the display shows the number of the currently selected
effect. (Pressing the button again bypasses the effect.)

When lit, the User LED below the display indicates that the current
Program is a User Program. When the LED is not lit, the current
Program is a permanent Factory Program.

Using The Footswitches

The Acoustic One's pedalboard consists of four footswitches: the far
right footswitch is the Bank selector, and the remaining three are
Program selectors.

A Bank is a group of three Programs. There are 10 User Banks in the
Acoustic One, each with 3 Programs for a total of 30 User Programs.
There are also 30 Factory Programs that can be selected using the
Data wheel only. User Programs in any of the Banks can be recalled in
one of two ways:

• Pressing the Bank select footswitch followed by footswitch 1, 2,

or 3, or:

• turning the Data wheel in Program mode.
