Hissing issue with Blackhole pedal

[SOTAG]

Hello,
I just bought a Blackhole pedal because I’ve loved the plugin for years. I added it to my pedalboard and noticed a huge “hiss” as soon as the effect is active—it’s a kind of very intense, very loud white noise that’s constantly present except in “relay” mode when the pedal is off.
All the videos I’ve seen online seemed to have a super clean sound… I don’t understand.
I’ve tried several different firmware versions, but even when I plug in just the pedal, the hiss is still there. It disappears in kill dry mode so I assume it is an analog dry through issue.
I’m using a mono rig—maybe switching to stereo would fix the problem?
Is there a solution?
Thanks in advance,
Guillaume

A shot in the dark … how is the Guitar / Line level switch set?  And is that appropriate to your signal chain?

My telecaster full volume goes to Polytune mini 3 > Cornerstone Gladio > RC Booster V2 > Strymon Flint > Seymour Duncan Vapour Trail > Eventide Blackhole> Amp
Every pedal is powered by Strymon Ojai
I’m playing low level but the hiss is here anyway…
I’ve tried Telecaster > Eventide Blackhole> Amp and the problem is still here…

Hi Guillaume,

Please contact support@eventideaudio.com. They can help troubleshoot the issue. That said, does this happen when the pedal is isolated from the rest of the board, meaning guitar > Blackhole > Amp? Running it mono or stereo, there should be no hiss. Make sure the back switches are set to mono and guitar level. Does this happen with every preset or just a single one? Have you tried powering it with the supplied factory adapter? Are you sure you are using In 1 and Out 1? I’ve seen cases of people mistakenly using Out 2 in a mono setup.
