Octave up and down in one pedal

[stezza]

Hi Guys,

I can't decide if my next project should be an octave up (octavia, green ringer etc.) or octave down (MXR Blue box or similar). So I think I'll do both. Does anyone know of an existing pedal/schematic that does this? As these pedals split the signal and then blend it back in, ideally there could be 3 signals - normal, up and down, with knobs to blend in the up and down. More likely I'll need to split the singnal at the start and run into 2 existing octave effects, then combine them at the end??? Any ideas guys?

build a green ringer and a blue box and put them in the same enclosure. have them running into each other and have true bypass for both.

Yea thats sortof what I was thinking. But how would that work? Would I need to split the input signal and run the effects in parallel? I'm guessing that if I ran them in series I would have problems with both on at same time. Has anyone used both types of pedal at same time? Does it work?

[snakey]

i've done this to a blue clipper and a green ringer. Built them on 2 boards and wired them in series, true by pass for both.

Wired like this:

(input jack) --> blue clipper --> green ringer --> (output jack)
                   \                       /     \                   /
                     ---> DPDT ---         --> DPDT --

Sounds good, do you have any pics? How does it sound with both on? any mods?

[snakey]

I have been meaning to up some pics i'll get around to that soon. it sounds fine both on, both off, 1 on 1 off. um its pretty much all salvaged parts so whatever i have that works i use . but no mods to get it to work no.

Thanks mate, I'll start breadboarding with my scavenged parts do you use PCB? I'll either go perf or vero if possible. U up late or down under?

I could be a good idea to do a bit of redesign so the two parts of the effect are fed from one input buffer and are fed parrallel to a mixing section and buffer out. this way you can control the amount of each octave level in the mix.

This is essentially what the EH micro pog does, right? Only you want an analog design that you can build obviously.

If you don't mine your octaves fuzzy and dirty you could have a look at this http://www.diystompboxes.com/smfforum/index.php?topic=76695.0.

yes and no.  MicroPog delivers octave up and down, but does so digitally, and polyphinically.  Big difference.

I have an old Ibanez 10-series Octave pedal, the OC-10, that gives you any combination of the fundamental signal, one octave down, and one octave up.   It's pretty cool, although like many octave pedals I like the sound of it feeding another OD/distortion pedal to keep it less "digital-sounding" (although I think it's analog).   Cutting out the fundamental tone, and leaving only the octave down and octave up is an interesting sound, and you can also get an Octavia-type sound by mixing the fundamental tone and octave up only.   Also like many octave pedals, it sounds best through the neck pickup with the tone rolled off, which is also how I use my Proctavia.  I don't know if there is a schematic available for it, but it might be worth checking out.  The upper octave is called "edge" on the pedal.

Has anyone ever pondered a "scaled-back" EHX Microsynth that skipped the filter and envelope stuff and just gave you octave up/down stuff?

I bet that would make an interesting project, and a board that could easily fit into a 1590BB.

i usually pcb, looks alot neater to me . Um it was 11 oclock at night in Newcastle Australia

Thanks for all the info everyone,

Can you explain what sort of input buffer and mixing section would work? This sounds pretty much what I'd like to do. The Pearl OC-7 and Super Octaver (although a translation would be good) also look cool, any more info on them? There's lots of good stuff out there, I saw a good demo of the bass blue box (meant for bass) which sounded really good. Anyone used one of these?

What about that ADA Harmony synth pedal? Or I should really say ADA Harmony Synth Workstation. That thing is a beast.

The Pearl OC-7 ... looks cool, any more info on them?

I was contemplating having a go at the Gaussmarkov DIY version of this bad boy a while back, but this was a few years back and it was just too daunting a task. I managed to snag an original on eBay, and I would heartily recomend having a go if you're up to the challenge. The two sub-octaves are much like the Boss OC-2, i.e. solid tracking, big sound, not too synthy. The upper octave is a bit like an octavia, i.e. slighty fuzzy edge, ghostly artifacts on double string bends, works best around the twelfth fret with neck p/u and tone rolled down, but it does a superb "robot ring-mod fuzz" if you play chords high up on the lower strings. With all three octaves on together + a bit of dirt, it sounds absolutely massive:

This is what I've been able to find on the OC-7 build





Anyone attempted this or have links to any further info? All I'm getting is alot of dead threads.
