Channel 1 1 2 5

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 the­footswitch* 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.

Boost Switch 3 4

Aboost 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 6 9

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.

Gain & Volume Controls 7 8

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.

Brightness Switch 10

Channel 2 includes a Brightness switch that activates a circuit to provide additional treble boost to help make your tone sparkle.

Master Controls

Tone Controls 11

The Treble, Bass, and Middle tone controls are to help you shape your sound. They are post-gain and pre-volume.

Reverb Control 12

The Master Control section also includes a rotary Reverb control that adjusts the overall reverb level for both channels. The YCV20 is equipped with a long- style Accutronics® dual-spring reverb for authentic vintage reverb.

Standby Switch & Indicator

14

13

 

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 when the 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.

EFX / LINE Send & Return Jacks 17

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.

Footswitch Jack 18

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.

External Speaker Jack 19

The chassis mounted ¼ inch jacks allow convenient connection of a 8 ohm external speaker cabinet. If you disconnect the internal 12-inch Celestion® speakers, you can connect up to two 8 ohm external cabinets.

Headphone Jack & Speaker Defeat 20

The headphone jack can be used with any stereo headphones. The headphone signal is post-preamp and pre-master. This means the signal is affected by all controls, including reverb, but not the Master Volume. For practicing silently, don't forget to disengage the speaker outputs by depressing the Speaker Defeat button.

D.I. Out 21

The D.I. signal is derived from the same source as the Headphones, the pre-amp. The balanced XLR output can be used to send the signal directly to a mixing console, poweramp or another line-level audio signal processor. Don't forget to disengage the speaker outputs (by depressing the Speaker Defeat button) if you like to record silently.
