I bought the FX bundle for $29. Happy with that, but really don't think I would want to spend the $129 listed price at all. Really I bought them only for the Enhancer & happy with it too. It pretty obviously has a mid Eq scoop as the main part of the FX but it also has other stuff going on under the hood. Summing amp seems to be what they're advertising and that makes sense. The enhancer is a weird effect (as most enhancers seem to be). It's not a simple saturation type thing though there is that onboard. The bass boost and high boost are more than likely just Eqs though the blurb mentions some phase processing. It has that magic box sheen that just does something to your mix to make it better. I had some fairly dense techno kinda mixes that it worked wonders on - it sounded more flattened but weirdly my analysers all said the LUFs value ended up lower than my original mixes that were heavily squashed - one of them was mixed to -9 LUFS and admittedly it did sound a bit quieter - it was peaking the same but told me LUFs was now -12. Now that has to be a good thing. Less flatline but sounded better, yet more squashed. Weird. Not sure I'll use it on all mixes but dense mixes it's a winner. My advice is keep the processing fairly low - it's quite an extreme enhancer.
As for the other FX. Meh. The delay won't give me any feedback for some reason. The phaser really doesn't do much phasing. The chorus is usable. TBH I'll probably delete the other FX but keep the lovely enhancer.
All plugins work well and sound very naturally, very good sounding Chorus and Flanger, Preamp and Enhancer also sound and work well.
Unfortunately I did not manage to get any convincing sounds from the Phaser. Phasing itself has little to do with other phaser plugins, which I know, instead of a convincing phasing the signal sounds - indenpendent of the settings - always completey distorted, even with Saturation at zero, worst with a square wave, better with a pure sine wave, nevertheless not at all what I would identify and accept as a working phaser.
Input reduction also does not help much. I personally suppose that this is some programming mistake, but as it is, the Phaser unfortunately is unusable for me.
If this mistake is corrected in a future upgrade, the whole collection would be excellent, so it unfortunately is only average.
