Another octave up + down

Im tryin to put together one of these. I know there are tons o threads on this but ive looked through them while deciding what to do and hit a wall.

Its the green ringer with full null switch and filter mod with the shocktave through the splitter-blender from run off groove, with a switchable bass fuzz at the end. I built
an orange squeezer and GR + bazz fuss in that order in one box. But wanted this more so ive taken the os out and put it in its own small box.

My problemnis i liked the box with two switches and wanted this to havw two. I wanted to be able to switch one on at a time. But with this idea, when i turn one off, then i have to mess with the blend knob.

I cant figure a way out to make it so i can engage each circuit alone and then turn the other on and have it blended in.

Could someone please help me figure this out?

Heres the splitter blender

I have the shocktave through the channel that has the phase switch. The way i hve it breadboarded makes it hard to switch around to see what it would sound like the other wau around.

Actually, could i also biuld anothe splitter blend channel to mix in the dry signal, so i could blend octave up, down, and in between??

Do i even need the jfet phase switcher part of the circuit? There doesnt seem to be any difference in the sound. Is this feature for certain other effects and the octaves will sound the same (cause they do) with the phase switched.

also When i dissconnect lug 1 and 3 of the blend pot the other effect comes through. I need to figure
out how to do this with two 3PDT switches. And light them with LEDs.

Sure!  The Shocktave already provides a mixing function, but you could do it either way.

Probably not.  A full-wave rectified sine has the exact same relationship to the original sine as it does to its polarity-flipped twin, so you would hear no difference.  For the octave down, you might hear a slight difference because of the added harmonics, but maybe not.

The shocktave mixes an overdriven sound in. I have a 3 k resistor instead of a 2k pot for the gain. But if i could
mix three signals together it would be cool.

So ill just take out the phase switchin portion of the splitter blender.

Im using ge diodes for the GR and Shocktave. Bass fuzz too. Bass fuzz will only be after the GR. I also matched the resistors for the octave generating parts of the circuit (i think) and the transistors. MPSA18 for the shocktave except the two input transistors. I used 2N5089.

They sound nice blended together. The dry signal was just a thought I suddenly had.

I really just wanna be able to turn each unit on with the splitter blend at the same time. But be able to turn the GR and Shocktave on individually. I think i would have to use the third pole of thr 3PDT switch instead of for LED indicators. Which i dont want. Also dont wanna order 4PDT switches!

Bump, dont mean to spam but ive been thinkin all day (im stupid) and cant figure out how i would do this.

Could someone please help me figure out a switchibg mechanism to turn the splitter blender on, while turning only one of the effects on at a time? Disconnecting the other circuit by removing the connect to the blend knob, makes the effect that is connected unaffected by the blend pot. But i cant fifure out how to do with this two 3pdts and still have true bypass for both switches.

Im dumb
