Doppoler Rotating Speaker Simulation System Modulation Effects Pedal

In fact, the Doppoler is NOT a “rotary simulator” but the brain of a system that in it's best setting is made of two cabinets, positioned at 180° from each other, to let the Doppoler handle what happens to the signal when the speaker is rotating. A lot of attention, measurement and tests were made to exactly understand and reproduce what happens to the signal coming to our ears with a rotary speaker. This meant to applying eq filters, phase changing, volume changing, and calculating how reflections react and affect all of this..

Indeed, the signal coming out from Front and Rear speaker are quite different from each other, because they are already made to do their job in the correct position. Speed sets the speed of rotary effect, and can also be set by the TAP tempo footswitch. Level sets the level of rotary effect and the ambient. The result, is an outstanding tridimensional sounds that will force you to keep it always ON, even with low speed and intensity without notice the rotary effect, just adding ambient and 3D to your sound.
