Nebulus

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!

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.

These pedals have a microcontroller in them that has firmware loaded on it. Occasionally we'll make small changes to the firmware. To find out which version of firmware you have, unplug the power from the pedal, then plug it back in. You'll notice that the LED above the "tap | preset" stompswitch flashes in a pattern of long and short red flashes. (Actually, if you don't get any flashes, that means you have version 0). It always starts with a long flash. A long flash represents a 1, and short flash represents a 0. The resulting pattern of 1s and 0s is a binary number that gives you the firmware version. If you know how to convert from binary to decimal, you're all set. If you don't, you can do the conversion here. Or you could just email us the pattern and we'll tell you!

For example, if you get a pattern that goes "long short long," that represents 101, which means you have firmware version 5. If you get the pattern "long long," that represents 11, which means you have firmware version 3.

If a pedal with a charge pump is placed in front of the Superdelay, Tape Delay, or Nebulus, and the charge pump noise leaks into the Empress pedal's input, there's a good chance a high pitched noise will be heard. This is caused by the codec in the Superdelay, Tape Delay, or Nebulus aliasing down the high frequency noise.

The solution is to a) stop using the pedal that is producing the noise; b) put the noise producing pedal after the Superdelay.

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 for details. We'll reimburse you for your shipping costs.

High pitched noise when using the Superdelay, Tape Delay, or Nebulus with some other pedal.

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