Reverb
The Galaxy includes a built in 2-spring, tube-driven reverb circuit. Reverb is applied to
both the Rhythm and Lead channels. In order to compensate for the higher gain of the
Lead channel, the reverb drive is reduced slightly on the Lead channel. This reduction
helps to match the reverb level when switching between preamp channels, when the
Lead channel is being driven hard and the Rhythm channel is set for a clean tone.
The Reverb level is controlled by the front panel Reverb control, which adjusts the
amount of the reverb signal which is mixed into the signal path.

Tremolo (Rate & Depth)
The Galaxy’s tremolo circuit is a form of the old-fashioned “bias modulation” tremolo
circuit. This circuit achieves the tremolo effect by varying the bias of the output tubes.
This type of circuit creates the tremolo effect by varying the gain of the output tubes.
This has the benefit of providing a nice smooth, rounded modulation effect, but it does
have some limitations. In particular, at very slow speeds, and/or high settings of the
depth control, you may hear some “thumping” or other sonic artifacts. This is a
limitation of this particular method – it can’t provide a very deep, “on-off” style tremolo,
like you would get with an “opto-coupler” type tremolo circuit.
The “Depth” control varies the intensity of the modulation effect, and the “Rate” knob
controls the speed of the effect.
If the footswitch is not being used, then the tremolo circuit is active all the time, so you
will need to turn the “Depth” knob all the way down if you do not wish to use tremolo.
When the footswitch is plugged in, you can turn the tremolo on and off with the
footswitch. An LED shows the status of the effect (LED on = tremolo on)
