Seppuku FX

[Howsyrface]

I purchased a Hystronic Modulator/Hysteresis on Reverb on a whim because of a good price, and I am kind of mystified by it so far. I'm not sure what all the controls do. It seems almost certain that the knob on the right hand side is wet/dry mix, and the bottom two knobs on the left are the two lfo speed. I think the knob above that might be how the two lfos are blended. No idea what the toggle switch and the push button do yet. Anyone had this pedal and could help me out? any suggested settings? Thanks!

Ugh I just played mine last month. I don't know the controls off the top of my head but let me plug in tomorrow and I can help you out. It took me a couple of minutes to "understand" what was happening.

Okay, following up. Gotta call a spade a spade here and say I have no idea what these controls do . I remember thinking that knob was the wet/dry signal too but...it isn't. Certain knob settings in different configurations give me a dry signal (which would make sense if the two knobs below are oscillators out of audio range?). It's an odd one. Two knobs are Oscillators of some sort that much I know. EDIT: On the site they are 'wide range oscillators' so maybe that has to do why they straight up oscillate to a 'tunable' pitch yet, act as LFO's in other settings (at some point in my playing, I got "mild" phasing/chorus sounds).
If all else you made me remember how much I enjoy that pedal though! If you get it to certain settings you don't need any drums on your track. The LFOS (let's call them WRO's ) crack up the amp rhythmically so you can get a four-on-the-floor crackling in your amp and play some space disco.

I thought the red button was 1. Wet/Dry together and 2. Just wet like on the Kompact Kassette. This pedal humbled me today... .

Hahah, thanks, glad you had some fun! i wonder what the mysterious toggle is...

Does anyone know how much an old Sub-Octave Synth would be worth now? Just found my old one in storage.

I paid 180 EUR for a brand new Octave Synth in 2014. Since Rhys' prices have gone up overall and these cool units aren't going to be produced again (I really doubt it), I'd say that the value is around 130 to 160$.

Octave Drone back in stock for those interested http://seppukufx.com/products/octave-drone/

I don't know if the recent models are as great sounding as my early Octave Drone. I have the first version (serial number 005!) with an extra mode:





Awesome with guitar, awesome with bass, awesome with drawbar organ, awesome with digital piano. I still have to try it with synths. I think that Rhys should have kept that drone knob which is a blend of normal distortion with the octave fuzz. Really versatile this way.

That drone knob sounds like a good idea - does it only work if the octave switch is on then? I've built this circuit a couple of times and added my own control to it to make it even more chaotic - you can watch a demo my son and I made of it here if you like:

Sounds great there, moid!

So what's the Cadillac seppuku effect? I've seen a few and I'm curious

Horizontal Memory Loss.

Horizontal Memory Loss.

Watched your demo for it! It looks pretty cool, kind of reminds me of the Echo Dream 2. Do you know if it runs a charge pump inside? The Echo Dream doesn't like the longest repeats and they get pretty ugly quick, but up to like 500ms they are pretty clean, and I mean it has a Fuzz knob.. Cmon! It's meant to be dirty. Does this pedal also have a "Wet only" switch? I'm not the biggest fan of that, but I think I just need to get a looper and layer that stuff with a reverb to make some ambient pad type noises.

Thanks for sharing

I've just started the work on cloning mine for shits and giggles (and knowledge), but I'm not a technical person at this point so IDK what a charge pump is. The button on the side is just a simple dirty boost. I'm probably gonna put that on the front of mine as a regular stomp instead.

Well the Echo Dream 2 uses an XR2206 modulation chip to generate the LFO, which runs at 10V or higher, (though there are reports of people getting it to work at 9.2V ish etc..) so you can use a 7660 chip or 1054 etc, to "Pump" your voltage up to 17ish Volts DC off a 9V source. I built one for my Echo Dream and run it at 15V, the oscillation circuit works way better. Originally I was running it off a 20V laptop power supply I ran through some 35V caps for filtration, it worked great too, but separate power supply for one pedal isn't my favorite. My ED2 is a clone I built bee tee dubs.

As for dirty boost, that's a cool feature. The ED2 just has a fuzz knob, which is a dirty boost as well. I'm not trying to compare this thing repeatedly to the ED2, it's just my only frame of reference on this type of effect!
Once again, thanks for sharing and I enjoyed your demo!
