Hi I got the TRBX 504 a few days ago. I like the tone and how it sounds but the hissing noise is mostly audible and distracting even if I increase the treble slightly. I tried it with an Amp (Rumble 40 v3) and also directly to my audio interface. I'm new to bass and I've never had any other basses to compare to. Is it normal or mine is faulty perhaps? Thanks
