Just got these things boxed up. Definitely a different approach to ring mod than I'm used to, with it implementation of a PLL oscillator / modulator that only spits out square waves.
While it can do some chimey adjacent tones, don't expect bells and ethereal clangs out of this- for that you'd need a sine wave modulated circuit. This thing is all about brutal, filthy squarewave Ring Mod. It does fuzzy, and it's not quite as predictable as say a Frequency Analyzer- some notes will cause a motorboating effect, some notes might seem to be barely effected at all. It handles chords well, and becomes a nasty fuzz with 5ths.
I definitely need to spend more time with it, as it's also quite different in timbre, tonality, and feel than the square wave mode on my Ring Thing. I like it so far for its nastiness, and it's incredibly easy to tune the Oscillator to a particular note. Tuning out the oscillator whine is dead simple, and the gate circuitry seems to work well with a wide range of Vactrols.
Super simple builds, beautiful board layouts, and @Robert offers the 565s with the boards
These two are largely identical, with one being built to spec according to the screen print, except the vactrol (ST VTL).
The other has had its frequency pot swapped from 50kB to 100kC so it can get slower and into choppy tremolo territory. This one is also using an LCR0203 I picked up from Amazon a while back. Which, according to the data sheet I was able to find, is actually identical in specs to the above listed ST VTL.
Both have 10k trimpot as I was out of 5k
I haven't tried a hand rolled LDR/ LED combo, but These cheap Vactrols, VTL5C3, and VTL5C1 all seem to work identically, so I wouldn't get too hung up on this particular part.
Looking at the datasheet for the 565, there are a few other potential mods, but I'll wait til the honeymoon phase grows wearisome before delving any further
As mentioned above, I'm still learning the nuances of this circuit, so this demo is pretty trashy, but I tried to cover the range of the pedal
The vid is with the 100kC Frequency Pot
Overall, I like this circuit, and I'd recommend it to other ring mod freaks. Super stoked to finally have a stand alone ring mod offered here, and you can bet your nippy that I'll be all over any others that release in the future
