Precautions
Power Supply
Always use a DC 9V center negative AC
adapter. Use of an adapter other than
that specified could damage the unit or
cause malfunction and pose a safety
hazard.
Always connect the AC adapter to an
AC outlet that supplies the rated voltage
required by the adapter.
Disconnect the AC adapter from the AC
outlet when during lightning storms or
not using the unit for an extended
period.

Always turn off the power before
connecting or disconnecting. Make sure
to disconnect all cables and AC adapter
before moving the unit. This will help
prevent malfunction and damages.

●Easy Controls, Wide Flexibilities
The Golden Tremolo features an easy-
to-use three-knob tone control: DEPTH
(effect depth), RATE (effect speed) and
BIAS (waveform bias) for using in
different scenarios. Each knob gives you
a wide control range.
●Unique Bias Control
The Golden Tremolo provides a bias
