Channel 1

Channel 1 is the lead/overdrive channel and is
selected either by the Channel Select switch on the
control panel or by the Channel Select button on the
footswitch* pedal. A Yellow LED located next to the
Channel 1 Volume control illuminates when Channel 1
is active.
*Note: Plugging in the footswitch deactivates the panel-
mounted Channel and Boost controls.

A boost circuit is provided to help achieve a-bit-more
overdrive, especially for leads. The boost can be
selected by the front panel switch or through the
footswitch. A Red LED illuminates to indicate when the
boost is active.

Channel 2 has been optimized as 'the clean' channel.
When channel 2 is active, the green LED located next
to the Channel 2 Volume control is illuminated.

Channel 2 uses a Gain control in conjunction with a
Volume control to control the amount of tube-based
overdrive and volume. The Gain control is used to
adjust the amount of overdrive, while the Volume control
allows you to set the actual loudness of the amplifier.

This switch controls the high voltage power being
supplied to the tubes. This mode effectively keeps the
tubes warmed up when the amp is not in use. The large,
jewel indicator on the front panel glows Red
amp is fully powered-up and changes to Yellow when the
high voltage circuit has been turned off. Putting the amp
into Standby mode (i.e. during set breaks) shuts off the
amplifier output stage and effectively increases tube life
by reducing wear on the tubes.

The Send and Return jacks of the YCV20 allow convenient
use of an external effect units. Simply connect a 1/4 inch
phone cable to the Send jack of the YCV20 and then
connect this cable to the Input of your effects unit. To send
the processed signal back to the YCV20 , connect the
output of the effects unit to the Return jack of the YCV20 .
The Send Jack can also be used as a direct line out
(preamp-out). The -10dBu output is ideal for most
guitar effects pedals and professional signal
processors. You can also use this output to slave the
YCV20 with another guitar amplifier by plugging into
the Return jack of the slave amplifier.
The 1/4 inch TRS Return jack is usually used as the
Return for your effects loop. It allows an input signal to
pass directly to the power amplifier. The Master Control
section regulates the signal, so you can add Reverb.

Connecting a footswitch to the 1/4 inch TRS
Footswitch jack deactivates the control panel mounted
Channel Select and Boost switches. These functions
are then activated exclusively by the pedal. The
included footswitch features dual-latching switches,
each with a separate LED indicator.
The switching is accomplished with internal relays
so there is no audiable noise flowing through the
footswitch cable. Footswitch-induced noise is never an
issue. The YCV20 is compatible with most aftermarket
latching dual-footswitch pedals.
