THANK YOU!

For purchasing a Morley pedal.

Please take a few minutes to familiarize yourself with

the feature of your new pedal. With common sense

handling, it should last for years. We know you will

appreciate the rugged construction of your Morley.

Most of all, we hope you enjoy it as much as we

enjoyed building it.

OPERATION

The ABC switch can take one signal (such as a single
guitar) and split it to your choice of three outputs - A,

B or C (see Example 1). It can also take three signals

(such as three guitars) and route them to one amp

allowing you to switch to either of the three (see

Example 2). LED indicators show which signal is

engaged at all times. NOTE: A cord must be plugged

into A in order to engage the unit.

The ABC box has two switches. The first switch

engages A or either B or C depending on which you
had previously engaged. The second switch chooses

between B or C. When The A signal is engaged, the

LED on the B/C side stays lit at lower illumination to

serve as a reminder to which side (B or C) will be on

when A is disengaged.

CONNECTIONS

Example #1 shows a setup in which three output

signals are used (two amps and a tuner can be

chosen). A would be amp #1, B would be amp #2 and

C would be a tuner.

EXAMPLE #1

Example #2 shows three guitars hooked up to one

amp. This would allow for quick changeovers of

multiple guitars.

EXAMPLE #2

You’ll notice that cords fit tightly into the ¼” jacks.

The tight fit helps cords from becoming accidentally

unplugged from the pedal. To avoid poor

performance, make sure cords are completely plugged

into the input and output jacks.

BATTERY

The ABC is designed to use one 9 volt battery. We

suggest you use a good quality alkaline battery. The

unit will function without a battery although the

LED’s will not function unless a 9 volt battery is

installed.

Your pedal is designed for long battery life. To

prolong battery life, unplug your cord completely

from “A” jack when not using the pedal. When the

pedal is not used for extended periods, we recommend

you remove the battery from the pedal or replace it

every six month to prevent leakage problems.
