8)SEND JACK This 1/4-inch jack delivers a tube-driven preamp signal to external effects devices. It can also be used to send the signal to another amplifier to run multiple amps.

Connecting a 1/4-inch plug does NOT break the flow of the amplifier signal.

9) RETURN JACK When the effects loop is active, this 1/4-inch jack breaks the flow of ampli- fier signal to allow an external effects device to “return” to the amp. The Return jack can also be used for a power amp input when using an external preamp. This all-tube effects loop is known as a “series” loop, since it breaks the path of the amplifier and “inserts” the

effect in series.

10) RETURN LEVEL This control adjusts the gain after the Effects Return jack, to adjust for an Effects Loop level nominally ranging from 0dBV(1VRMS) to -10dBV(0.3VRMS). This control should be set to the lowest level that provides unity gain when using your effects, when com- pared to the level if the Effects Loop is disabled via the footswitch. However, using the Send and Return Levels, you can easily get up to 10dB boost when using effects. This can be very helpful when using effects like delay or tremolo where the level appears to be lower due to the nature of the effect. Because the Effects Loop is a series connected loop, this control will

adjust the overall volume any time the Effects Loop is active.

11)FOOTSWITCH Before powering up the amplifier, connect the provided 5-button footswitch here using a 1/4” TRS stereo cable. The Channel

Selector knob on the front panel should be set to Footswitch when the Footswitch is being used. If it is not, the footswitch will blink when channel se- lecting, but the channels won’t change. The footswitch selects between Rhythm, Lead I and Lead II channels; enables the power amp Boost; enables the Effects Loop. To select the appropriate channel, simply press the switch you want to activate. After doing so, the footswitch remembers the last channel, so you can toggle back by hitting this same switch again. This allows the user to jump to and from a channel quickly without having to look down at the footswitch. Any changes on the footswitch will be mirrored on the front panel of the amplifier.
