Mauman, very much appreciated that you took some time out. You are right of course on the mV for the higher V.

I got her working. To my ears having Q2 right under 7V beefs it up and slightly smooths out any mudiness. Less than that and itís too thin for me but itís all about preference.

But I guess itís a pedal you to pretty much dime out or at least that is how it is for me.

Again thanks for giving me a hand.

You have 121V at basis of transistor? Try to measure it again. Ground probe of multimeter at ground at power plates, and hot probe at points you need to measure. And measure even ground at the desk, if it is connected with ground of power supply.

Zerro, what do you mean put the ground at the power plate?

I've measued this thing multiple times. Right now it reads 118v. Same way i've always done pedals. Put the ground to the enclosure. Of the 6 test points of the two transistors 5 are spot on within range of what the BOM suggests and then there is this odd ball. I didn't know it was possible to generate that voltage in this pedal.

I'm fine with just getting another board and doing a new one but I might end up with the same issue. Bad transformer maybe? I believe the pin orientation is correct though or the other test points would be off too I would think.

Bringing this back up. So I still can't figure out this wonky voltage reading but now the pedal doesn't work or rather it does, just no fuzz. I guess my first thought is to confirm with someone other than myself the transformer is in the proper position. From everything I've researched it is. Anyone with any thoughts?

My guess is your foot switch failed.  Try jumping the pins on the 3PDT dedicated to the LED and see if the LED works then.   

I've over heated a few 3PDTs before and lost the function of only one column on the switch.

I was thinking this as well. I may just order a new switch pad .

Jimi itís the footswitch pad that something is wrong at least I think so.

Got distracted for a bit.

Does anyone have a guess as to what the ground lug is on this switch pad? I've tried to figure it out but can't be sure. This LED thing has me stumped.

General Questions / LED question - Horizon
« on: July 12, 2021, 07:21:38 AM »
I guess if you build enough pedals you run into firsts. So I built up the Horizon, amazing pedal love it, and used it for a few months. Then one day the LED doesn't come on. The pedal still works. I think no biggie, bum LED so I swap it out. Nothing. So I figure let me pull it off board and wire directly to jack. No go but here is my question.

Can I ground the LED to any ground point? I thought I could. Typically I don't use 4PDT boards and wire the LED's with the ground attached to the 3PDT. But since this build uses the 3PDT board I can't do that. So, I just wired it to my main ground point at the input jack with the 9v anode directly to the DC jack like normal.

Anyone have any troubleshooting thoughts? Did any of this make sense?  :)

So, I just finished testing this one and it is working but I have quite the wonky voltage reading. I'm thinking it might sound better, or how it was designed, if I can figure out why this weird voltage reading. All other readings are on par. Anyone have any thoughts?

Q1
C = -.68
B = 121.4   :o
E = 0

Q2
C = -4.38
B = -.68
E = -.55

Anyone have a good source for this? Is there an equivalent for this build?

Ok thanks. Iíll be out of town for the next several days so Iíll pick back up on it then. Thanks Scruff.

If you don't have a scope, just audio probe pin 7 & 8 of each BBD while adjusting its bias.

I don't have a scope but I think I've got it dialed in real close.

However, what does it mean when I get zero sound out of pins 7 and 8 of the BBD's, IC's 3 & 9?
That they're not passing signal and you have no effect... when working, you should hear clean undistorted vibrato on each chip there.

I still get no signal from the BBD's on pins 7,8. I can say with 100% certaintly some type of chorus signal is passing through. Can't tell you how but when you click it on an off there is a audible difference but that explains my subtle comment earlier. I also get no signal from pin 7 of IC 2. I do get signal from a few other spots that I mentioned earlier in the thread so I know my audio probe works.

Scruffie, could a tant cap issue be the problem?

I don't know if I'd call it a subtle chorus pedal, it doesn't really sound like most others. If you have a scope to calibrate the pedal with, that will make it A LOT easier to do. Since this has two BBDs in it, the first BBD is easy to dial in (the pedal starts to chorus) but the second BBD is harder because it's sound gets placed "on top of" the other's chorus sound. If you don't have a scope, I guess the best way to describe it is that when the second BBD gets dialed in, the chorus sound gets "thicker".
A scope makes it so much simpler though ..
Hope this helps

BTW, switch "4" will give you the most pronounced chorus sound. The Blueshift kills when used as a stereo chorus. The "lushness" comes in when used in stereo

Thanks for the explanation as it was spot on.

Success! Just about peed myself.

So I fiddled with the trimmers after starting at 3.4v but have a question. Is this a subtle chorus? I ask because the switches change the sound a little but not a lot. Same with the trimmers. Iím wondering if I need to look at some other things to get more Ďlushnessí.

I realize by separating the boards I sort of created my own monster so Iíll own it if by doing that I may have altered things.

Thanks for the sympathy thoughts Gordo  ;D
