    Just got a MB Compressore ... wow, talk about a buttery smooth sound. Amazing how much control it offers.

    Although I'm perplexed about something that being the tube doesn't glow at all. Is this normal for this unit?

    What about those of you that have one. Does the tube glow in yours?

    Some tubes don't glow very brightly. The one on my old Compressore was very faint so I don't think it's an issue.

    Mine does glow. Even with the pedal disengaged.
    And I though that was an issue… :)
    But as long as it is sounding good…

    That's how mine was. In some light you can't see it at all.

    That's normal.

    Some tubes glow more than others. The stock 12AX7s in my Orange Bass Terror light up like a Christmas tree, but the Gold Lion ones I put in there don't glow at all.

    Some pedals have silly LED lights that make the tubes look like they are glowing brighter than they really do.

    I was asking myself the exact same question.. (Thank you search engine).
    Now that I know my tube is working as intended with the very uneven slight toaster like lighting, I notice that it stays "lighted" even when it's not in use, and it stays warm to the touch.
    There is no power on/off switch. Should I unplug it when not in use or is it OK to leave it plugged all the time?

    Technically leaving it on does shorten the life of the tube, but in practical terms that might mean the tube lasts only 20 years instead of 40. :)

    Mine barely glows. You can see it from the right perspective but only if you are looking for it.

    I unplug mine when I am not using it. But as Bongo said it won't make that much difference. I ended up not switching tubes in mine. Likely will at some point in the future but I want to learn first whether the tube is active in the gain stage.
