You wont find an unsynthy, simple Octave down DIY Project to be honest, BOSS OC-2, PAIA Rocktave Divider or The multiplexer are your best bet, or of course the POG which is great but a bit expensive.
An no file attatchment option, PM me your E-mail and i'l send it to you.
Clean Octave.. Won't happen with DIY i'm afraid, i'm currently working on some designs and it's gunna be a long process and a huge build but analogue octave being fuzzy and glitchy is just the nature of it, you really have to go DSP to get clean octave.
Well i have the OC-3 and it gets that annoying digital glitch.. *grumble* I will have to look into those other octaves. Or maybe i can EQ the fuzz out of it? Hmm...
If you want the OC-2 I have a simplified only 1 Octave down schematic for it http://www.aronnelson.com/gallery/main. ... ewsIndex=1 dunno how good you are with schematics, theres the Pearl OC-7 aswell which is supposedly good too, I have the schematic for that floating around somewhere...
Well you can EQ it to an extent yea, there are mods that can be done to help aswell, compression with it would help too, alot of the simpler or subtler octaves need alot of gain to bring out the octave which is why you end up with distortion... it's all very complex, my project is only in the early thinking stages (cause I don't have any money lol) but I shall see how that goes, I will be working to get a clean Octave out of if though...
And isn't the Jawari more of a sitar octavey sound?

I played some crazy fucking electric sitar thing in some guitar shop in london the other week. Playing chords on it was bollocks. The single note stuff, that was awesome
not worth £650

I can do schematics no sweat. :]

I've been on an octave up quest for a while - just built myself a green ringer and a jawari. The jawari beat out everything I've tried so far.
The Foxrox is awesome. Is there a schematic for that guy floating around?
I think i wanna do the OCD and Foxrox in the same box. I don't think i'd need the high, but if i can't get rid of it, than so be it.
I wanna do one footswitch for an OD/octave, Basically it'd be like sticking the OD directly infront of it, and just tagging it on after.
or should i do two footswitches... thoughts?
Should i go with the Foxrox? cuz i've been looking and nothing touches how clean that octave is
Why not have the OCD on a standard footswitch then stick the Octave in the same box with a simple DPDT toggle switch to turn it on and off as an option? That's what i'd do anyway.
Crazy Guitar thing eh? Sounds like a Line 6 Variax, which guitar shop was it? Denmark street? And most octave pedals do track single notes better, they get confused with chords poor things... even the really big expensive Pog gets confused sometimes, the micro less.
Fraid I lack an Foxrox octron schematic, it hasn't been RE'd yet as far as I know, there are gutshots if you wanna try though.
Hmmm. That would more than likely make more sense. I was thinking maybe a footswitch, but than i realized i probably would do better with a toggle. Is there a way that i could have the toggle on and still have a footswitch for the channel... I was thinking FS1 would turn the whole pedal off and on, and then toggle switched to the octave channel would turn the octave on. But i want a footswitch available to turn the octave channel on & off when the toggle is flipped. Is that possible, cuz that would be the pedal of my dreams
Well, they show the basic workings of the Foxrox in this video on a *schematic* like thing:
Maybe Guts + Schematic thing =

Wasn't a Line 6, infact i think it was the company that makes Dano guitars before dano, or other way around, bobby jones or something... i forget.
Scruffie wrote:Thinking of that switching made my head hurt lol, perhaps just stick to two footswitches otherwise the toggle seems kinda pointless...
Have you ever Reversed engineered anything from a gutshot cause i'm yet to, don't think it's that easy... surprised it's not a SMD or DSP circuit though.
The mixing idea of the block diagram is a line my pedal was heading down, glad to see it's a good idea... but I intend to make my circuit simpler but I shall see what happens...
Oh and I forgot... it's a double sided board making life more difficult.
If you happen to have BOTH sides of the PCB, than i can probably rack my brain over it for a while.
Well if i have two footswitches, can the first one act as a killswitch as well? like i can be using the pedal and hit that one and turn it off? i'm pretty sure i'm just an idiot and that was a roundabout way for me figuring out that i'm in fact an idiot. I'm pretty sure you can do that, now that i am thinking about it.
And yea you can kill the whole circuit at the main footswitch and then have the octave foot switchable seperatley
(Using 2 DPDT)
Wire the Octave True Bypass As Normal, In on the right side of the switch, Out on the Left side Run the out side (which would normally have gone to the out jack) of the DPDT into the OCD Circuit and the In Side (which would have gone to the input) to the In of the other DPDT switch then run the Out of the OCD Circuit as normal and then the rest of the switch like normal... that is a bit confusing but without being able to link a photo it's a bit hard to show you.
