Dear Mr. Neher,

I have a problem with my 350X SWR amphead. When i plug my bass into the amp, I turned the volume up and at first the sound sounds good but as soon as I play about 5 notes there is a very loud buzzing noise and it never stops and I know it is not the speaker because we pluged that into another amp andit sounded great so i am thinking it has to do with the inside of the amp and i am sitting here right now with the amp open so i am ready for any help and if you don't know if you could please direct me to someone who will.

Thanks,
