610hlf speakers lighting up?

    Sometimes while playing loud I notice light flashing from the inside of the cabinet. Shining thru the speaker cones!

    What does it mean? Some sort of clipping light?

    Protection circuitry for the tweeter often uses a lightbulb to soak up excess high frequency energy.

    It's a bulb that disipates the extra energy as light instead of letting it through to blow up your tweeter/speakers

    Basically when things start lighting up your cab is at it's limitations and you should back off a bit

    Well back off the highs, at least.

    Thanks guys, would you turn down the knob on the back of the cab or use the eq on the bass and/or head?

    I usually have my treble/tweeter knobs at noon.

    Are you using overdrive/distortion when it happens?

    I loved my 610HLF and the only time I got the light when I had my ODB-3 kicked up too loud.

    I had the same problem with my 610HLF. It would only do it when I was using my SYB-5 synth pedal at loud volumes. I turned my tweeter off and adjusted my pedal so it wasn't so loud when I use the effect and it fixed my problem.

    Now that I think about it, it happens when using a tech 21 sansamp petal.

    When you use a distortion pedal, it overloads your highs and upper mids to a crazy level that tweeters have a hard time dealing with. So I would suggest turning off the tweeter completely when using distortion.
