Two green ringers in series - two octaves up?

[freddd]

^^ Just wondering if it works, I quite fancy a double octave up pedal!
Thanks.

interesting, but i dont think it would work?


we'll find out...next, on DIYstompboxes.....

It would probably get pretty nasty because you would be feeding it two notes at a time, although octaves may not be as bad as a disparate pair of notes. I think the key would be to feed the second one only the octaves from the first one to get a "clean" second octave. Might hurt your hearing even if it did work--or maybe only be audible to dogs?

I've tried it long ago and since the Green Ringer has a lot more in its sonic soup than just octave up, the results were a little sloppy.

While they'd seem to cancel each other out, the Blue Box and Green Ringer in series (in either order) sounds pretty cool.  Here are some clips: http://www.diystompboxes.com/smfforum/index.php?topic=37545.msg187636#msg187636

Try the E&MM Harmony Generator project posted at my site (http://hammer.ampage.org).  This uses a 4046 tracking oscillator to generate notes above and below the original.  I'm confident it can be coerced into producing a note two octaves up or somewhat cleaner quality than a pair of octave fuzzes in series.

Whoa.  Whoa.

The CMOS phase locked loop thing sounds like a way to a more obvious +2 octave, but I could see the two green ringers in series being an interesting sound, I'd put a LP filter before each one (like the tone knob on your guitar), to clean up the overtones.  A simple RC filter would do, or if you want more rolloff there is a GR specific filter on the GR page at GGG I drew up a while ago.  Wow thats a lot of abbreviations.

2 octaves up is pretty piping.

Two octavers in series will give a lot of dirt and inermodulation distortion, and sometimes ring modulation effect. Adding LF filter (about 400-600 Hz cutoff frequency) after the first octaver and cutting the HF with the guitar tone knob will improve the situation considerably. The sound will be a kind of "synthesizer" sound.

You might have some success doing something similar to the Z. Vex Jonny Octave route - using audio transformers.

The Blue box/Green ringer device sounds brilliant! I'll have to stick one of those on my to do list. Does anyone know which octave engine is at work in those jonny octave pedals? That sound is exactly what I'm after....
