INTRODUCTION

Thanks for choosing the DigiTech® Nautila chorus/flange pedal. The Nautila was designed for the
selective guitarist who wants the highest quality effects in a compact package. The Nautila provides
such distinguishing features as true bypass, constant high voltage operation, and true stereo processing,
making the Nautila an essential addition to the signal chain of players who know about sound quality
and demand the utmost in performance with superior tone and control.

The Nautila is a stereo, multi-voice chorus/flange effect pedal. It offers the usual control that you would
expect when using a chorus or flange effect: mix, modulation speed, depth, and regeneration. But what
sets the Nautila apart is the additional creative control on offer.

For example, when the chorus effect is selected the EMPHASIS knob can be used to control the tone
of the effect. The number of voices is selectable using the VOICES knob, with up to 4 flange or 8 chorus
voices selectable. The continuously variable, 360° DRIFT knob lets you morph between waveforms, for
truly unique modulation movement. And if that wasn't enough, press and hold the FOOTSWITCH when
the effect is on and the modulation rate will speed up or slow down, for expressive control during the
performance.

To use the Nautila pedal, enable the effect with the FOOTSWITCH (the LED will light when the effect is
enabled). Select the desired effect type (chorus or flange) with the toggle switch. Set the MIX control
to the 12 o’ clock position so you can clearly hear the effect. Adjust the SPEED knob for the desired
modulation rate. Adjust the DEPTH knob for the desired effect intensity. Adjust the EMPHASIS knob to
alter the tone (when chorus effect is selected) or adjust regeneration (when flanger effect is selected).
Select the number of VOICES with the VOICES knob. Adjust the DRIFT knob to alter the modulation of
the effect. You can re-adjust the MIX control for the desired blend of wet and dry signals.

1. Effect Type Selector Switch

Selects between the chorus or flanger effect.

2. DC Power Jack
Connect the specified Harman power supply (sold separately) to this jack. Be sure to use the proper
power supply for your area’s mains line voltage. See 'Specifications' on page 9 for power supply

model information. The Nautila can only be powered using the external power supply.

3. Drift Knob

Varies the shape of the modulation sweep. This is a continuously variable, 360° control which
allows for morphing between triangle, log/asymmetrical, and sine wave shapes.

4. Emphasis Knob

This knob works differently depending on whether the chorus or flanger effect is selected. When
chorus is selected, this knob provides a tone control for the chorus effect signal. Turning the knob
up past the 12 o'clock position will enhance high frequencies in the effect signal, and turning the
knob below the 12 o'clock position will reduce high frequencies in the effect signal. When flanger
is selected, this knob will control the regeneration (the amount of effect signal fed back into itself),
which dramatically enhances the flanger’s harmonics during its sweep.

5. Voices Knob

Selects the number of effect voices. At the minimum position a single voice is used. The maximum
position provides 4 voices for the flanger effect or 8 voices for the chorus.
