Of course, players can recreate tape flange in this exact way. Engineers used to use
a third tape deck to record the resulting flanged signal, but any recording device
will work. However, the more punk rock version of this effect uses only four things:
two mics, some tape and an oscillating fan. Yes, that is correct.
Mic your speaker cabinet on one side, then use the tape to attach the second mic
to the rotating shaft of the oscillating fan. Turn the fan on and position it such that
when the fan has reached maximum rotation, the mic is the same distance from the
speaker cabinet as the other mic, and be sure to set this up so that
the mic swings on an arc away from the cabinet, then back to
the original position. Feed both mics to the same channel,
turn on the amp and fan, and boom, that’s a flanger. As
a bonus, if the fan has three rotation speeds, that’s a
three-speed flanger. If it has an adjustable speed, that’s
a flanger rate knob.
