INSTRUCTIONS
Adopting the stereo-out system, the BOSS
effect unit CE-3 is able to produce exter-
mely rich chorus sounds. By controlling the
RATE and the DEPTH knobs and the
STEREO MODE switch, you can obtain
wide variations of the chorus sounds.
Moreover, the CE-3 is designed to be noise
free, i.e. the S/N ratio is more than 90 dB
(IHF-A). Also, you can easily see wheather
the effect is on or off by the indicator
which lights up when the CE-3 is in effect
mode.
• Please read the instructions carefully .
