SOLVED Duo phase wiring, rate and switches

I have just finished a duo phase, picture attached. The rate seems pretty fast, maybe slightly faster on one side than the other. Do the trimpots affect this? Or is there a mod that can be done to get a bit more range in the rate?

It's wired stereo at the moment and seems to be just two separate pedals period, only work if you plug into all jacks, for some reason I thought that if you plugged into one side you get to use both still? Or should I just rewire it in mono.

Also the switches don't seem to do anything, is this due to the way I have wired it?

The rate being slightly different on each side could come down to part tolerance (caps being +\- 20% etc)

Plug your guitar into the right most jack, and out to your amp from the left most jack...if I'm remembering correctly. It's been a few years since I made one.

Ok, is there a mod that can be done to slow it down at all?
Looking at the photo with this thread, I have realised I have the stereo jack on the right side, does that mean when the pedal is flipped over I should be plugging into the left side looking at the face of the pedal?

I'll use the drill template as a guide, as it's facing the right way.

Red is from guitar, yellow is to amp. The switches will only do something if it's operating properly thru the connections or you are only connected to side B.

On my build I used switched jacks for the first out and the second in. Your second in uses a regular jack, although I’m not entirely sure that’s your problem. The other thing: there are no LDRs on your right side?

The other LDRs are on the underside of the board, to help isolated the two sides. And I'm really not sure if I have the switching jack wired correctly at all. It looks like I have the ring of the stereo jack connected to the tip of the next sides input jack. Is that right, I think that is what I saw in the documents.
I'll have a quick read of that post that Giovanni linked...

Yep, I'm an idiot. Just assumed the jack was a stereo jack because it had 3 lugs in the pretty picture. Didn't even know what a switched jack was. They say you learn something new everyday. Now I'm going to have to get some switched jacks. I believe that should solve most of my issues.
Does anyone know if it can be modded to slow the rate down a little?

Ok, the only switched jacks I could get from my local electronics store are these. I actually don't know what to connect where. Nor can I seem to find info on them when I google. Please help!

Do you have a multimeter? You can use it to verify which lug connects to which of tip, ring and switched ring. You may need to insert a jack in the plug to verify the switch connection.

So one of the other leads should be connected to the tip when no jack is plugged in and open when the jack is connected. That’s the lead you need to connect to the next one.
