when the effect is engaged� Use the FOOTSWITCH to engage and disengage the effect� Also indicates Power Up Mode features� (See page 8�)

DECAY

Controls the decay time of the reverberated signal from 1 second to over 50 seconds� Lower settings reduce the size of the reverberated space�

PREDELAY

Sets the amount of time before the reverberated signal appears, an essential control in creating an accurate and pleasing reverb� For most natural results, use lower MIX settings when using higher PREDELAY

�

FOOTSWITCH

Engages and disengages the effect� The RED LED on at the top of the pedal indicates that the effect is engaged�

NOTE: Press and hold the footswitch to configure Expression Pedal parameter assignments� Please see page 13�

You can optionally configure an external footswitch for FREEZE or INFINITE mode functions� (See page 16�)

Knobs and Switches

Front Panel Controls

ENSEMBLE

Analyzes the input signal and generates a harmonically rich

pad reminiscent of a string section:

off: (left position) no ensemble effect

: (middle position, mezzo piano, meaning “medium soft”)

a medium amount of ensemble for a subtle enhancement

: (right position, “strong” or “loud”) maximum amount

of ensemble effect creating a lush soundscape

MIX

Controls the reverb mix from full dry at minimum to full wet with no dry signal at maximum� A 50/50 mix occurs at approximately 3 o’clock on the knob� (See page 8

for Dry Signal selection�)

TONE

Adjusts the high-end content of the reverb� Lower settings create darker, warmer reverberation� Higher settings are bright and crisp�

MOD

Adds a wide range of modulation to the reverberated signal� Modulation is off at the minimum setting�

Rear Panel I/O and Control

I/O MODE SELECTOR

mono : (left position) use with a mono input signal, such as a guitar�

Output is mono� Defaults to True Bypass�

mono stereo : (middle position) use with a mono input signal� Output is stereo� Bypass mode is Buffered Bypass�

stereo : (right position) use with a stereo input signal� Output is stereo� Bypass mode is Buffered Bypass�

Stereo I/O requires a TRS adapter or cable� (See the following examples�)

IN

High impedance, ultra low-noise, discrete Class A JFET TRS stereo preamp�

OUT

Low impedance TRS stereo output�

Mono and Stereo I/O Cable Connections

The cloudburst In and Out jacks can accept either TS or TRS type 1/4” cables for mono or stereo connections, respectively:

NOTE: With a TRS stereo connection, the Tip carries the left signal and the Ring carries the right signal�

pg 5

Mono In - Mono Out: To connect cloudburst in a mono signal chain, use TS cables for both cloudburst’s IN and OUT� Set the I/O Selector switch to mono�

Mono In - Stereo Out: To feed a mono signal into cloudburst, use a TS cable to cloudburst’s IN� Connect a TRS + dual TS cable to cloudburst’s

OUT to route cloudburst’s stereo signal to a stereo pedal� Set the I/O Selector switch to mono stereo�

Stereo In - Stereo Out: To connect cloudburst in a stereo signal chain, use TRS + dual TS cables into both cloudburst’s IN and OUT� Set the I/O Selector switch to stereo�

*NOTE: Alternatively, you can use a TRS - TRS cable when connecting a pedal with a TRS stereo input (such as connecting to the TRS stereo input of an El Capistan tape delay)�

Power Up Modes

Bypass Mode for Mono I/O

With the rear I/O Mode Selector set to mono, the cloudburst pedal is set for True Bypass as the default� Setting cloudburst to Buffered Bypass Mode preserves the high frequency response of your instrument’s signal through your pedal chain and long cable runs�

NOTE: With the rear I/O Mode Selector set to mono stereo or stereo, the bypass mode is automatically set to Buffered Bypass�

1 Press and hold the footswitch for at least 2 seconds while powering

up cloudburst� Once the LED flashes, release the footswitch�

2 Toggle the ENSEMBLE (BYPASS MODE) switch to choose between

True or Buffered Bypass Modes� The LED will change color to indicate the current status as you toggle the switch�

• Buffered Bypass: set the switch to the (right) position� The LED lights RED�

3 Press the FOOTSWITCH to store the Bypass Mode and begin using

cloudburst�

NOTE: The Bypass Mode setting persists across power cycles�

pg 8

Power Up Modes

Spillover Mode

Setting cloudburst to Spillover Mode allows the wet reverb signal of the currently selected preset to “spill” into bypass—or into the next loaded preset if you’re using a Multiswitch Plus or MIDI for preset switching�

NOTE: Because of the buffer architecture, the current preset must be active for at least 5 seconds before Spillover between presets will be operational� Spillover is available immediately when bypassing the effect�

1 Press and hold the footswitch for at least 2 seconds while powering

up cloudburst� Once the LED flashes, release the footswitch�

2 Turn the MOD (SPILLOVER MODE) knob to set Spillover Mode on or

off� The LED will change color to indicate the current status as you turn the knob�

• Spillover Mode Off: AMBER (default, minimum)

• Spillover Mode On: PURPLE (maximum)

NOTE: When Spillover is set to On, Bypass Mode is set to Buffered Bypass�

3 Press the footswitch to store the Spillover Mode setting and begin

using cloudburst�

NOTE: The Spillover Mode setting persists across power cycles and is not saved per preset�

Power Up Modes

Dry Signal

The Dry Signal can be set in one of three different ways�

• Digital Mode uses the converted dry signal and allows the MIX knob to dial out the dry signal when turned past the 3 o’clock position�

• Analog Mode keeps the dry signal in analog�

• Kill Dry Mode mutes the analog dry path signal, allowing the MIX knob to strictly control the “wet” effect output level� This is often preferable if using cloudburst within an amp’s parallel effects loop or a mixer’s aux or effects send�

1 Press and hold the footswitch for at least 2 seconds while powering

up cloudburst� Once the LED flashes, release the footswitch�

2 Turn the TONE (DRY SIGNAL) knob to select one of the three Dry
