General Operating Instructions
Plug the speaker cord (supplied with the unit) into the Speaker 1 output. Check the ohm impe-
dance load of the cabinet you are going to use and adjust the impedance selector switch on
the rear panel of the amp accordingly. Make sure that all controls on both channels,
inclu-
ding Presence and Resonance on rear panel , are set to the 12 o'clock position. Set Clean
Channel and Lead channel volumes to zero. Turn on the amp using the Power On switch
on the rear panel. Wait about one minute and then turn on the Stand By switch on the rear
panel. The amplifier is equipped with a timer that starts functioning only when the tubes are
sufficiently warm. This lapse of time is indicated by the flash of this led.
We suggest the use of the supplied foot-switch to select channels. To do this please connect
the supplied foot-switch to the foot-switch input on the rear panel.
Please note that inserting
the foot-switch automatically excludes the selection switch on the front panel.
Connect now your guitar’s chord into the input jack on front panel. Every time the amp is tur-
ned on, it will automatically select the Clean channel. Twist the Clean channel Volume knob
to the 9 o'clock position and PLAY!
Your new 2/50 Head features very sophisticated tone circuitry that makes it possible for you
to produce an array of customized sounds. Use the tone controls to achieve the sound you
want. We recommend that you refrain from applying extreme tone equalization settings.
Adjust the Pesence and Resonance controls on rear panel and add the desired level of bottom
end and brightness to your sound.
Now please select the Lead channel, either by switching the relevant button once or using the
foot-switch. Twist the Volume knob to the desired position. Adjust the tone controls to achieve
the desired effect, just as you did with the Clean channel. You can also customize the amount of
overdrive by turning the gain control.
Remember, while playing at high volume levels, lowering the bass control may improve note
definition and increasing the treble and mid controls may help to project the sound further and
cut through the groove. Increasing the Resonance control while playing at low volumes, may
help to add punch to the overall tone of your amp.
Using the Fx Loop
First, you have to decide whether to use a series or parallel effects loop connection.
The difference between the two effects is that, in series mode, the signal going from your
guitar through the amp to the cabinets is subject to the quality of the effect, whereas - in
parallel mode - the original sound of your amp reaches the cabinets intact, meaning that the
quality of the effect is not compromised in any way.
Proceed as follows:
If you want to use the parallel effects loop connection, select only the wet signal on the
effects unit. Now use the Level knob to mix the level of the processed signal to the original
sound of your amp. If you want to use the series effect loop connection, set the switch to
series and select the desired mix of wet and dry signal on the effects unit.
