Hey! The Field Kit is likely not the most noise-free device out there, in big part this is due to the high amounts of amplification available from the 'GAIN'-setting. Every Field Kit mixer channel has an input gain of x1000. This is necessary to amplify low-amplitude signals like the pickup coils for example.
The noise floor of a Field Kit mixer channel, using professional line level signal as the reference (+4 dBu / ~3.5V peak to peak), is down ~60dB. With full 6.5Vpp signal as the reference level, this translates down to -65dB. This is of course far from todays digital -100dB noise floors but that's also not we are trying to compete with.
You can compare the noise/hiss you are experiencing with the aforementioned numbers if you have access to a DAW with some sort of a Spectrum Analyzer utility. If the noise floor is around the aforementioned numbers, there's nothing wrong with your device! Also, don't get confused with dBFS / dBU.
In any normal condition / use case the noise is not perceivable if any wanted signal is present at any given time. Also, proper gaining really helps.
I hope this answer cleared out some things!
