    just picked up an swr 2x10 super redhead, second hand.

    when I turn it on it has a pretty nasty sounding buzz coming from the speaker, which increases in volume as you turn up the gain If i twiddle the speaker on/off switch I can get it to stop/diminish in volume for a bit. Tried recording out from the di and no buzz is there.

    Any ideas? Summat not grounded propor? Just a loose wire? Gonna have to take it in to be looked at I guess...

    Dodge :meh:

    sounds like a problem the signal chain either between the preamp and poweramp or between the poweramp and speaker (depending on how the speaker on/off switch is wired)
    try running another cabinet in the speaker out jack and see if it buzzes as well - all in all it sounds like an easy thing for a tech to diagnose
