Hi, I've just got a new Spider V 20 MkII as an upgrade to my Spider III. I was surprised and disappointed to hear the loud buzzing and high-pitched whine coming from the amp on all settings except clean. My Spider III is completely silent on all modes, including INSANE. The Spider V is pretty much unusable because of the noise emitted when there is no significant input from a guitar. I have tried changing guitars, changing instrument cables, using different power sockets, moving to different rooms, but nothing seems to improve it.
I can remove a lot of the noise using the Spider Remote noise gate and adjusting gains, but I don't see why that should be necessary with out of the box, factory preset tones.
Is there something wrong with my Spider V amp or is this just something this amp does?
Any help in getting rid of this unwanted buzz and whine is appreciated.
Thanks
