Master Controls - Traynor Custom Valve YCV40 Owner's Manual

Boost Switch
3 4
A boost circuit is included to help you achieve 'a-bit-more' overdrive for leads. The boost can
be selected via the front panel switch or through the supplied footswitch pedal. A Red LED
illuminates to indicate when the boost is active.
Channel 1 Tone Controls
6
The Treble, Bass, and Middle tone controls are used to help you shape your sound. They
are post-gain and pre-volume. These are active only when Channel 1 is selected.
Channel 2
8 9
Channel 2 is the clean channel and thus has no Gain control. In other respects the layout
is the same as that of Channel 1, with independent Volume and Treble, Bass, and Middle
tone controls. When channel 2 is active the green LED located next to the Channel 2 Volume
control is illuminated.
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

Presence Control
12
The rotary Presence control is part of the Master Control and adjusts the amount of edge or
presence (upper midrange) on your overall sound.
Reverb Control
13
The Master Control section also includes a rotary Reverb control that adjusts the
overall reverb level for both channels. The YCV40/YCV40T is equipped with a long-style
Accutronics® dual-spring reverb for authentic vintage reverb.
Standby Switch & Indicator
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
The Send and Rtn jacks of the YCV40/YCV40T allow convenient use of an external effect unit.
Simply connect a 1/4 inch phone cable to the Send jack of the YCV40/YCV40T and then connect
this cable to the Input of your effects unit. To send the processed signal back to the YCV40,
connect the output of the effects unit to the Rtn jack of the YCV40/YCV40T.
The 1/4 inch TRS Send jack can be used as part of an effects loop in conjunction with the
Rtn jack. It 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 YCV40/YCV40T with another guitar amplifier by plugging into the Rtn jack of the
slave amplifier.
The 1/4 inch TRS Rtn jack can be used as your return jack for your effects loop. It accepts
an input signal that is passed to the power amplifier, so it can be used as a power amp in. The
Master Control section regulates the signal, so you can add Reverb as well as Presence.
Footswitch Jack
19
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 YCV40/
YCV40T is compatible with most aftermarket latching dual-footswitch pedals.
