EHX Good Vibes?…

[Coda]

Wasn’t there a PCB for this in the works? I can’t find any mention of it anymore.

 

[Big Monk]

I’d kill for a schematic. I’ve been dying to see what makes my Good Vibes tick.

I’m seriously thinking of keeping the Good Vibes and Electrovibe.

 

[Coda]

Thinking about it a bit more...it wasn't the Good Vibes, it was the Pulsar...which is also absent from the Coming Soon list...

 

[Big Monk]

Well, I’d send my Good Vibes to @PedalPCB to be traced if there was any interest.

Yep, you're thinking of the Pulsar. It's been postponed because of some of the issues surrounding the original circuit.

@Big Monk I'd certainly be interested in seeing what's in there. Can you snap a pic of the PCB?

I suspect there are going to be some digital elements in there. I thought it would be 100% DSP but the description says there are photocells, so it's probably a digitally controlled analog circuit.

Here you go!

it's using 4 nsl32's for the lamp and cells, that's interesting!

I noticed when I opened the much smaller values for Speed and Intensity. Also just a single gang Speed control.

 

[Robert]

Yep, I suspect it has a digital LFO. (Judging by the PIC microcontroller over beside JP1)

 

[Big Monk]

I just got a response back from EHX for thier QC document they use to set the internal trim pot. I just set it back to factory and am going to test it today.

It's a sweet pedal for the price and with the expression pedal it has a lot of versatility. Especially since you can assign Intensity or Speed to the expression.

The madbean harbinger 2 is like that as well I believe.

Right. I believe his Harbinger 2 is a form of R.G. Keen's UVICS design.

I know the pictures aren't a lot to go on, but above there are 2 tests points, TP1 and TP@, that EHX shows in their QC document for adjusting the voltage with the trimpot.

Any idea what they are adjusting there and going higher than the 3.86 v they suggest would do for the tone?
