    Hello evrybody !

    I recently purchased a Marshall DSL5CR, while overall I am very pleased with its sound, there's one point on which I have mixed feelings: like a "whistling", a metallic resonance, which especially superimposes when I am playing on the high strings. That's particularly audible on chords or when I let ring notes.
    An example here, on a D chord: http://soundcloud.com/alexis-ferreira/test-ampli/s-HkG0pV4HOjN

    In a first time, I would like to know if it's not only me ! :rofl:
    And I would like to know if it's normal and it's just a part of the amp identity (maybe I just struggle with its brightness and higher frequencies), or if it's unusual and what could be the cause of this.

    What I already tried, without result:
    - Tried with other tubes and an another speaker
    - Tried on the two channels
    - Tried various settings on the amp (except for Trebble at 0 ...)
    - Tried with an other cable Jack
    - Tried with the two humbucker of my guitar

    Thank you a lot :thumb:

    From your description it sounds like tube rattle, probably from the power tube. It's the vibrations from the speaker that causes the tubes to vibrate. Try gently tapping the tubes to see if you hear it.

    A good test is if you have an external cabinet that you can try, place the amp where there aren't a lot of vibrations.

    Thank you for your answer !
    Unfortunately I don't have an external cabinet !
    I tried to gently tapping the tubes, but nothing special ! They seem good

    Do you hear a similar sound when playing the same chords acoustically (Guitar not plugged in)? If so could be a bridge rattle on one or more strings. Does it happen when playing a different guitar through that amp? Ringing in the amp's audio circuits while not common can happen though the usual culprit is microphonic tubes. However to my ear the ringing sounds a bit too high frequency to be tubes.

    What guitar do you use? Does it do it with more than one guitar?
