The Nebulus brings guitarists high quality chorus, flanger and vibrato effects in a really compact 4.5 by 3.5 inch pedal. To increase the tone range even further 3 variations on each effect are available for a total of 9 tweak-able modes. All this flexibility is easy to access via a preset system capable of storing up to 8 different presets.

The chorus mode offers a lush and warm sounding chorus, a fluid and dreamy multi-chorus, and a unique tremolo'ed chorus. The flanger setting has a classic tape flange, a 70's negative feedback type flanger, and the elusive thru-zero flange. Lastly, but certainly not least, are the vibrato sub-modes which include a standard vibrato, a classic vibe sound, and a rotating speaker effect.

Each mode includes a special switch which allows the guitarist to really tweak crucial settings and it also offers some bonus features like the ability to add compression to vibrato mode, for example. For further fine tuning, a tone switch is available offering warm, clean, and bright voicings to the effect.

This true bypass pedal offers the uncompromising sound quality that guitarists have learned to expect from Empress pedals in an incredibly small box. With chorus, flanger and vibrato all only one touch away, this pedal is an incredible value.

User Manual & FAQ



Empress Nebulus User Manual



Question: When I save a preset, then power cycle the Nebulus, the preset is missing. What's going on

Answer: There was a bug in some of the early Nebulus' pedals. If you have serial number 100 or below, this bug might be affecting your pedal. Unfortuantely, the only way to fix it is to update the code, which means you'll have to ship it in to us. Please contact us at support@empresseffects.com. We'll reimburse you for your shipping costs.

Question: What kind of bypassing does the Nebulus have?

Answer: The Nebulus has true bypass switching. It uses a relay to switch. It also does buffered bypass. You set what kind of bypassing you want in the advanced config.

Question: When I load a factory preset and I change any of the controls, is that change stored?

Answer: The default is for presets to be altered when the controls are moved around. So if you go to a preset, crank the output knob, then exit that preset and return to it, the output will be cranked. You can change the default behaviour with Advanced Configuration. You can set the 'presets write protect' options to one of three things:

1) The default (left position), which is where presets are written over when you move the controls. Great for experimenting.
2) Write-protected (middle position) where the controls affect the sound, but the preset isn't written over. Great for being able to mess around with knobs during a show, but have your presets not get messed up.
3) locked mode (right position): adjustments are completely disabled except for in manual mode. Great for if you have the perfect settings that you don't accidentally want to change with your foot during a show.

I suggest you check out the Advanced Configuration in the manual. It's got a bunch of goodies!

Question: Can I use the Voodoo Lab Pedal Power 2+ as the power supply?

Answer: Yes. But you need to use outputs 5 or 6 of the Voodoo Lab Pedal Power 2+, and have nothing plugged into the other output. Also, you must set the corresponding DIP switch away from the NORMAL position. Also, if you have the 230V version of the power supply, we're not sure if it will work.

Question: I'm using the Voodoo Lab Pedal Power 2+, but it's not working! What's up?

Answer: Check to make sure you're not using the SAG outputs of the PP2+. Our pedals don't work with the SAG outputs.

Question: Is there an external tap tempo jack? Can it be modified to include one?

Answer: There isn't one, but you can replace the tap stompswitch with a jack for external control. Be aware that the tap stompswitch also controls the preset system, so you'll be messing with that too. You'll need an isolated mono jack like this. Here's the steps to do the mod:

1. Unsolder the wires from the two terminals on the tap stompswitch.
2. Use a wrench to remove the tap stompswtich
3. Use a wrench to fasten the isolated mono jack to the enclosure in place of where the tap stompswitch was.
4. Solder the two wires to the mono jack.

On older versions of our pedals, we used latching stompswitches, which look like this (the one in your pedal might only have two terminals). On new versions of our pedals, we use momentary-close switches, which look like this. So the signal that you send to the pedal has to be the same as whatever stompswitch you're replacing.

Question: Can you guys do the mod to replace the tap stompswitch with a jack?

Answer: We don't do mods, but the fine folks at Nice Rack Canada do. Send them an email at info@nicerackcanada.com.

Question: I play bass! Can I rock out through this pedal?

Answer: Yes! All of our pedals play nicely with bass. Check out the "Features & Specs" section for information on the frequency response of our pedals. We have lots of customers who play bass through our pedals!

Question: Can you mod my pedal so that an expression pedal jack controls one of the knobs?

Answer: No, sorry. But it's not a hard mod to do. Here's a good resource on how to do it: Add an Expression Pedal to Any Effect. If you don't want to do it, you the fine folks at Nice Rack Canada do. Send them an email at info@nicerackcanada.com.

Question: The pots turn easily, so they move when I accidently hit them during a show. What can I do?

Answer: One of our customers has a great solution to this problem. If you wrap rubber bands at the base of the pot it makes it harder to turn.
