I used the more desirable/sought-after ‘T’ model featuring an output transformer which adds a little extra color to the sound. You may perceive this as subtle ‘grit’.
Here is what is in this release:
- A high-pass only program. The higher input levels sampled were sent into the unit hot to get some dirt/grit, but plenty of range was sampled so you can also get a cleaner sound. The user can quickly and easily use the Nebula ‘trim’ control to decide exactly how hot of a signal to send into the program, and how strong any harmonics coming out will be. The unit’s input impedance was switched to ’10K ohms’, which generates more harmonics. The input level sensitivity was set to ‘0db’ which triggers the harmonics at lower levels.
- Low-pass by itself. Sampled the same way as the HP-only effect.
- A combo with both the HP and LP together. This one was sampled with dynamics also, but the whole sampled range was below saturation level. This one was sampled with the unit’s input sensitivity set to ‘+20db’ and the input impedance to ‘600 ohms’, both producing a very clean output.
- Each of those 3 configurations are presented with 1k lite/clean programs, and ‘full’ version programs that have several orders of sampled harmonics. The lite/clean programs can be used for a cleaner sound (they still have the sampled dynamics), or if you want lower CPU use.
- All 3 configurations were sampled with dynamics included in the actual filter program. You don’t need to load another program along with these to get the dynamic behavior, it’s right there with the filter. Most Nebula filter or EQ programs aren’t like this. It takes a lot more work and makes these things a lot more complicated to make, and they also take a little more resources (CPU) than usual. This is because they are made up of many more samples than a typical Nebula program of any type.
