A month wait mate ? Wow.
More likely some form of variable voltage regulator.
I variable resistor (or equivalent) could be used, but it will increase the impedance of the power supply as you turn the power down, which is not ideal.
Most amps will have this problem to some degree, as the signal sent to the reverb tank varies with the guitar signal (and indeed volume settings on the amp).
Hammond had an ingenious gain reduction circuit in their reverb circuit (an incandescent bulb!), but I've not seen this circuit in a guitar amp.
Perhaps in most amps the tank is driven hard enough at modest volumes that variations in drive don't have that great an effect; reverb tanks don't generate much more reverb once the input is driven beyond a certain point, almost like some form of signal limiting.
