ok, I get a very annoying distorted sound when I'm using channel one with my guitars (takamine,taylor).
the level is set to 50% and the master volume too , no eq settings no reverb, no tone.
the distortion is more in the lower frequencies and it seems it depends on special resonating frequencies.
the distortion efx rise up in the release phase of the sound itself and there is no change when I lower or rise
the master volumen, so I think it got to do with the amplifier itself, not with resonating box parts ... very sad, because the FX150 is very awesome , exactly what I'm looking for -so I will send this unit back and hope the next one got not
this problem !
there is a red led blinking into the FX150 itself, I can can see it very clearly through the XLR connectors on the backside, is this a normal behavior ? the blinking is the whole time, from switching on till off ... ah, and yes I have done all updates ...
