INTRODUCTION:

Inspired by the old-yet-innovative rotary speaker systems, like the old

Maestro Revolver, Leslie, and mostly the "Doppolas rotary speaker" made

by Mr. Gilmour & Mr. Taylor, with the DOPPOLER, we wanted to make a

pedal that really reproduce the rotary eﬀect in a physical way, just missing

the mechanical parts.

in fact, the Doppoler is NOT a "rotary simulator" but the brain of a system

that in his best setting is made of two cabinets, positioned at 180° from

each other, to let the Doppoler handle it reproducing what happened to

signal when the speaker is rotating.

We paid a lot of attention, measurement, tests, to exactly understand and

reproduce what happens to the signal coming to our ears with a rotary

speaker. This meant to apply eq ﬁlters, phase changing, volume changing,

and calculate how reﬂections reacts and aﬀect all of this.. Indeed, the

signal coming out from Front and Rear speaker are quite diﬀerent from

each other, cause 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. A very transparent

Tube preamp make your sound great respecting your instrument, and you

can easily add an overdrive pedal in front of it like our Sexydrive mkII with

his blend option, to add beautiful drive to your Organ sound.

What we keep in mind designing the DOPPOLER is the ambient and 3D

sound, people asked me to do some kind of "leslie simulator" for years,

and i've always replied that i don't want to make a simulator of an

instrument where the acoustic component of the sound was so important.

So we started designing it from the acoustic point, wanting to keep it intact

and the base of our system, then we designed our circuit to reproduce

what happens between the cabinet and our ears. So far from a simple

tremolo/rotating simulator.

You can easily use it in your pedalboard in front of your amp, and easily

add just an additional speaker behind your main speaker.. maybe an active

cabinet, a combo amp, or using one of our Miniamp to drive a guitar

Speaker.
