Does anyone have the schematic for the ‘Scenario Preamp’? The cornerstone Gladio SC. I could’ve sworn I seen it on a thread her, somewhere. And, if not, Robert, can we PLEASE?! get the schematic???

CONGRATS!!! I love the feeling of getting a stubborn pedal working!! Btw, here’s a site for an audio probe. You NEED to make one of these, they help out A LOT! https://www.diypedalgearparts.com/en/novita/26_Audio-probe-how-to-build

Damn! I was hoping it fixed it for ya. You have an audio probe? That may help to find where your problem is.

If the mids is working, maybe it has something to do with the caps going to the treble and bass pots. Or a cold solder joint on the pot lugs. Idk just a thought.

Thanks for the reply!! I’ve given up on this board for right now, and just ended up making a vero board version of the Dane. I know the leads on that cap were not shorting out, and I made sure the orientation of that cap were correct. I had swapped that cap out, and in the process of taking the...

All ya gotta do is look at the traces. The trace for the gate is sent to the bottom pin which means your orientation is correct.

That’s cool your friends sending ya another matched set. I think that’ll fix your issues. As for the distortion, the only way I could ‘get rid’ of it, was running it at 12v. I haven’t tried 18v yet, because of the 15uf cap. Mines only rated for 16v. But I believe they can be run at 18v so long...

Was your soldering iron on when you heard the sound?

If I were you, I might get a cheap component tester off the bay of E, or Amazon, and check those Jfets. Even build a JFET tester. There are vero board layouts for that. Just to make sure your Jfets aren’t the problem, ya know. Because those Jfets that are running at a lower voltage don’t seem right.

Not a problem. On mine, the voltages on the Jfets are all the same on all four. I’m getting 5.14v on drain and source, and a fluctuating around 2-3v, I think, on the gates. Idk if it’s weird or not, but my ‘magic spot’ on the trimpot is just north of 3v. I doubt any of this will help, hope it...

It’s hard to tell, but it doesn’t look like it, do you have anything insulating the backs of the pots? If not, then they could be shorting out som solder joints on the back of the board

First, ya definitely need to reflow all solder joints, and clean the flux off the bottom of the board there. Most issues are solder bridges or cold joints.

Nvm, I figured it out. It was a loose fitting op-amp.

Ok, so, I built an ‘Xc phase’ on vero board with a layout from guitar effects, I think. I can never remember the sites name. And, I’ve had it working for a bit, then all of a sudden it stops phasing. I’ll get pics tomorrow, but I’ve checked all voltages, components and placements are correct...

I had a couple issue with this build the last couple days. Although, I built a vero board version, with script switch, and depth knob. I was going insane last night with the trimpot, until I noticed that if the pots are turned down, it’s hard to tell if there’s any phasing goin on.lol idk if...

Are we any closer to getting the updated pot and kettle schematic???!!! Please Robert?!?!

https://tagboardeffects.blogspot.com/2014/04/cornish-g2.html?m=1 Scroll down, and the comments section will start right after the layout, I believe.

I found some info on the vero board site. They talk about your issue also. Here’s a couple screenshots I took of their discussion. I’ll post the site in a min.

Have you tried re-flowing all solder joint? Make sure there’s no solder bridges, and check all component values and placements?
