i just got a new Bongo, and I'm trying to diagnose a constant "hiss" coming from the bass. The hiss is present no matter what pickup setting is selected and is not cured by putting hands on strings. I have eliminated all other possible sources, going direct to multiple amps, and still having the same issue. No other bass I own (8 currently) have this sort of hiss. The hiss is present across a wide swath of the frequency spectrum, and can only be reduced with dramatic eq cuts. Batteries have been replaced, multiple cables tested. Issue still persists. I'm working with EBMM now, but curious if anyone else has had this issue with a Bongo HH.
