When do I change the tube in my Valvedrive?

    The pedal isn't functioning and the mute button isn't on.

    The valve will last many, many years. Odds are there's something else wrong.

    More details, perhaps? Lemz - let us know what you've tried to do so far. Does it bypass? Is it plugged in? If it shares a supply with another pedal, is the other pedal working? What happened before it failed? Etc.

    For all we know, it could just be the adapter not working, or something fried, or aliens. :meh:

    I about to give it another run in a few minutes. It does bypass, but when I hit the pedal to engage it pops. No shared supply it has it's own 12v which was completely plugged in. It has gone in and out of this 2 times before and do I though the tube might be going. Thanks guys

    While tubes can and do go bad sometimes, far more often a solder joint somewhere connecting to it (or to the power jack) will go bad. If it was the tube, I don't think it would work and then cut out and then work and then cut out. That, to me, says bad solder joint.

    While I'm a HUGE fan of this pedal (& frankly, cannot live without it), the footswitches are prone to premature failure. I doubt it is the tube - but it never hurts to have an extra around! Preamp tubes are pretty inexpensive & you may find a tube you like better than the stock Setlana - I did.

    I took my Valve Drive apart & cleaned out the switches with a healthy dose of pot cleaner - which did cure the occasional loud "pop" I was experiencing. Something you may want to try if you're experienced with electronics - there are potentially dangerous capacitors inside!!!! Since cleaning out the footswitches, my Valve Drive has been 100% reliable, but for some reason the yellow "vintage" led mode doesn't light - it goes from red to off.... :meh:

    That would drive me crazy, since mine's always on yellow.

    Yeah- it's a little bit annoying, I'm really picky about my gear functioning 100%! I would ship it off for repair except that:
    -It still sounds perfect
    -I love & use the pedal so much, I'm unwilling to play without it for a few weeks!!!

    At least the "Modern" setting still glows red so I know where I am, but I wish EBS switches were more reliable! My uber-old Octabass switch failed completely so I replaced it with a better one, but the Valve Drive switches are sort of proprietary & soldered to a board so I can't fix it myself! Aaaarrggh:scowl:

    Love this pedal though..... I can't say enough about the tone!

    It's embarrassing.....input/output plug in wrong
    Thanks for your help guys and sorry bout my mistake.
     

  13. The amount of time I do that is embarassing. Must be something like 80%. And most of the time I think to myself " Right, I was going to plug it in that way instinctively, so if I switch that round it must be right." And then it turns out wrong. :meh:
