I've been watching this thread. I'm curious how this one compares sound-wise with your Phase Revolution? I've been playing the heck out of that guy pretty much every day, and I love it, especially in the box with a Magnus Modulus. Does this phaser bring something new to the table in your opinion?
The concept with this project was for a phaser that anyone could build with no matching of components. Do a search for builders who have issues around FET matching in Phase 45, Phase 90 and Phase 180 builds and you'll see what I mean.
This is my third phaser build. My first was the Phase 45 with Maillet mods
a.k.a. Phase Evolution, I was so disappointed in the (lack of) phasing that I added two extra phase stages, which makes it a nice phaser, somewhat akin to the Phase 90. My second was the Phase 180 Plus
a.k.a Phase Revolution, it's taken some tinkering to get it near to what I want, and I'm still not entirely satisfied with it. Causality 4 has some great sounds, more flexible IMO than my Phase Evolution, easier to use than my Phase Revolution - as you'll know there are a number of settings on the Phase 180 which just do nothing.
So, all in all, Causality 4 is not trying to compete with a Phase 180. It has a sound of it's own, there are no settings that 'do nothing', and the Depth control works particularly well and gives a broad palette of tones. I'd say it's probably 'more' than a Phase 45 or Phase 90, and an easier build than either of them. For it's sound, simplicity and utility, Causality is my favourite of my three phasers right now - but I do have the PCB's to build an 8 stage Ross Ropez, to which I'll add 8 extra fixed stages making 16 in all, I'll have each set of four stages switchable, and it's going to have every concievable mod................
