EHX Pulsar, found LFO ticking cure

[Cortex]

Ok, now when I have your attention, I must admit that I found nothing of the sort. I just noticed that the only thing, the only god-damn thing that will stop it to bleed ticking [and I tried A LOT] is to put my Korg DT-10BR tuner before it. Done. No ticking at all. I couldn't believe it.
I had all my pedals in boxes for months, and when I finally connected em all together in the board, I noticed that the Pulsar is not ticking, I was overwhelmed by happiness. Then I switched things a little, put a tuner in the end of the chain to see something, and ticking reoccured. Then i disconnected everything, made this little chain, guitar => Korg DT10-BR => Pulsar => amp, and everything was smooth as butter.

Now, the schematics for the Korg DT-10BR can be found very easily on the interwebz, and Im sure some of you [or most of you] that transcend the knowledge that I have about these matters, will come to some conclusions that we could all benefit of. Of course it's the buffer, impedances, yada yada, but I don'thave the necessary knowledge to dig deeper.

So maybe that kind of buffer could be built into the Pulsar clones and prevent ticking for all of you out there that are annoyed by it. I know that I am, were. But I never ditched the pedal cause it sounds great!

Sorry if this topic is an everybody's waste of time.

Add this buffer:



Point "E" should be 2V to 8V DC.

Please reply on-forum not in PM. The problem is of general interest.

Trimpot R10??

That should have NO effect on the voltage at point "E" in the added buffer.

If you are sure of your number, then C1 is shorted or there is some wiring flaw I am not going to see from here.

added this buffer, but it didn't help with ticking issue

hi,

here is a groundbreaking advice on tick-prevention by puretube:

and here, too, by KG (who also had no ticking issue):

not my ideas, I only posted the links

great thing you tried them, and that they work!
