Open High Hat- intermittent fault, no decay and short crunch

I've got an intermittent fault with Yocto V1 with the open High Hat having no decay when turning knob and just a crunchy corrupt burst of sound with just attack sounding fine, then it fixes itself to correct and later fault returns.

I've sent it to tech and he cannot replicate it(now working Again), but I fear if not fixed the problem will return after I get it back, any idea of this fault, something starting to degrade or bad connection?

Thanks..

This sounds like a bad connection to me. It's not fun, but I think you'll have to go over the circuit very carefully checking for cold solder joints, cracks, etc. Good luck! I hope you fix it! This type of problem is frustrating I know, but nearly impossible to debug over the internet...

There is a problem with Yocto V1 that causes the open High Hat to have no decay while rotating the knob. Instead, there is a crunchy, corrupt blast of sound, and the attack sounds perfectly normal. Sometimes the problem corrects itself, but then it starts happening again later. I have already given it to a technician, and he is unable to replicate the issue (although it is currently working again). However, I am concerned that if the issue is not fixed, it will reappear after I receive it back. Do you have any idea what the issue could be—perhaps a bad connection or something that is starting to deteriorate?

I'm having a similar problem, I think you should check the circuit very carefully for cold solder joints, cracks. It seems annoying. Hope to fix it with you soon.
