Nope, mine sure doesn’t sound anywhere near that noisy.

That sounds a bit hissy.

Here’s the things I’d test, if I were trying to run down a problem:

Recording clean to your input, no amp or mic in the chain. I’d even remove the guitar, just plugging a dummy chord into the input to turn it on. If possible, I’d run the pedal off of batteries, making up a battery pack so I could completely rule out noise from an odd line problem.

Using that basic set-up, so I’d know nothing extraneous was involved, I record with the pedal bypassed and on, but with only the dry signal on (both octaves turned completely down). If I knew what unity gain was for the pedal (normal unaffected volume equal to volume with pedal on), I’d use that setting for this recording.

I’d record with the effect on, dry off, and sweeping the lower octave from completely off to halfway, then to off again. Then I’d record it from completely off to halfway, wait a bit, then to full, then to halfway, then to full, then to halfway, and again to off.

I’d do a similar recording for the upper octave.

At that point, I’d be able to tell if the problem was possibly a frequency being introduced at an unnoticed pitch by the guitar, amp or microphone, or if it was coming from the pedal. Following a similar procedure, I was able to show that my Musket v2 was generating a noise internally, and that it wasn’t my set-up. I’ve also had occasions in the past where the pedal wasn’t at fault, but was merely sensitive enough to uncover a problem with other gear which had gone unnoticed.

Just out of curiosity, you write English very well. Where exactly are you located that EHX gear is completely out of reach for comparison? In most places in North America, for example, although it might require a little travel, one can usually get to a major city with music shops.

I’d be interested in hearing what happened, should you pursue the above procedure in your quest for closure….
