?What could be the cause of a hissing sound.

[Mickyk]

I seemed to have acquired a hissing sound resonating through my cab speaker when i am using my Sansamp which is connected to the FX Return jack on my  Amp to the out Jack on the Sansamp.

This hissing doesn't happen when i'm going directly into the Amp only when using the Sansamp.?Any ideas anyone.

Probably a gas leak.

Have you got a Sidewinder speaker in there? 😎

what time of day was it?

 

i used to experience this strange hissing sound during the summer every night at around the same time - after observing the pattern it turned out it was always exactly around 3am - so after several nights listening from the bedroom window  i decided to go out the front door into the garden to see if i could hear it any better or identify where it was emanating from 

 

turned out to be the local pitch and putt golf course (council owned and run) using an automatic watering system on their greens that was set to a time in the middle of the night when everybody would be fast asleep and hence nobody would realise what they were up to during a rather long hot summer with its accompanying hosepipe ban  🙄

If you have bass with active electronics: how is the battery state?
