?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.

How high up is the Presence control, this can be a tad hissy if high up.

Probably a gas leak.

Have you got a Sidewinder speaker in there? 😎
