LITTLE LEHLE III AS AN A/B SWITCHER BETWEEN TWO AMPLIFIERS
L I T T L E L E H L E
M A D E I N G E R M A N Y
The LITTLE LEHLE III can be extremely
useful for switching, when playing live
with two amps, for instance, between the
clean sound of amp A and the distorted
sound of amp B. It also enables you to
switch quickly between familiar sounds,
or to compare A and B, when you are in
the studio or the rehearsal room.
HOW TO DO THIS
1. Connect your instrument to the input
socket (1) of the LITTLE LEHLE III.
2. Connect the Send (3) of the LITTLE
LEHLE III to the input of the amplifier 1.
3. Do not use the return socket (4).
4. Connect the Output socket (5) to the
input of your amplifier 2.
5. There you go!

Output
Most amplifiers are connected to a pow-
er supply using a three-core cable: two
cores supply the power, while the third
core is the equipment grounding conduc-
tor which grounds the amplifier.
If this ground core is installed, it must, for
safety reasons, never be removed, taped
off or disconnected!
Because of the grounding and the signal
ground of the guitar, two amplifiers con-
nected to one guitar can generate back-
ground noise.
This background noise is called "ground
loop". You are guaranteed not to have
ground loops when you use the LITTLE
LEHLE III, because it not only switches the
signal back and forth between the ampli-
fiers, but also, simultaneously, the signal
ground.
