nebulus user manual
Introduction Modulation effects are sort of like spices, used tastefully they can elevate a dish into flavour country. With Nebulus you get it all, 9 different spices that will cater to just about any modulation meal you're after. Along with the sonic versatility, we've included 8 presets for the most demanding live sets. A hybrid of analog and digital, the Nebulus harnesses the best of both domains. The Advanced configuration mode lets you tailor the functionality to meet your needs in any situation.
Quick Start Chorus: Smooth Swirling Chorus Vibe: Classic Vibe Flanger: Big Sweeping Flanger
The Modes Chorus A - Basic Chorus Mode: By basic we mean that this chorus is basically perfect sounding: lush, beautiful, deep, you get the idea. The special switch allows you to get rid of some of the low frequency throb that is often associated with chorus effects. Chorus B - Multi Chorus Mode: This mode offers a rich and thick multi-tap chorus sound. Again, the special switch allows you to roll out some of that low frequency throb. Chorus C - Tremolo Chorus: A blend of chorus & tremolo together.
Vibe B - Classic Vibrato: This is a full featured vibrato that will give you more warble than you'll ever need. The special switch adds compression to the vibrato sound which is a match made in heaven. Hint, if you just want to just use the compressor, turn the width to 0. Now you've got a 10th mode....but who's counting. Vibe C - Rotary: This mode gives you the Doppler spin and amplitude modulation of a rotating speaker cab.

Chorus has a smooth, rich shimmering quality adding dimension to your sound. Vibe is a pitch modulation effect that adds a warbly feel.
at a Glance Tone: Changes the tonal charachter of the effect. V - 12V DC negative 0mA or greater Bright will add some high end. Clean will leave the signal uneffected. Warm will darken the sound. Special: Modifies the effect. Perfroms a different function for each mode. See the cart at the upper left to reference the funtionality in each mode. Output: Sets the overall output level(volume) of the pedal. Depth: Adjusts how wide the effect will modulate.
Advanced Configuration Entering the advanced configuration: Unplug the power from the Nebulus. Plug the power back in while holding down both the tap and bypass stompswitches. The bypass LED should blink twice to confirm that you are in the advanced configuration. Modifying the advanced configuration: Each toggle controls a configuration parameter. When a parameter is modified, tap LED will blink to confirm that a change has been made.
Advanced Configuration at a Glance Presets write protect: Choose if presets are write protected or adjust on the fly. left(default): presets rewritable center: presets are writeprotected. Any changes made while in a preset will not be saved. right: “Locked” control adjustments are disabled in all presets except the manual prest (white LED). Presets: Choose how many presets are used.
Using Presets The Nebulus allows you to save and recall presets. All settings of the pedal are saved in a preset and each preset is represented by a different color of the preset LED. To load a preset, use the preset stompswitch to scroll through presets. The LEDs will blink, indicating the preset of that color is ready to load. Press the bypass switch while the LEDs are blinking to engage the new preset. To modify a preset, just move a control.
Adjusting the Headroom The Nebulus has an internal switch which allows for the adjustment of the input headroom. This switch is accessed by removing the back plate. The pedal ships with the switch in the -6dB position, which allows for an input level of +5.1dBu. If the input to the Nebulus is especially loud, and you are noticing distortion under normal conditions, you can increase the headroom by moving the switch to the -12dB position.
