Ebs Valve Drive volume drop?

    So I bought a valve drive from some guy on the interwebs. It gets to my home, I just do a very quick check to make sure it turns on and sound comes out, and tell the guy it arrived in good shape.

    Putting the pedal through the paces today, I found that it has a significant volume drop off. I checked and made sure that the pad button was "off" and used my Rick and my jazz with an audere 9v preamp for testing.

    In order to get the same volume out as if the pedal was bypassed I have to have the volume cranked all the way and the gain at 12 o'clock minimum.

    Would this be a tube problem? I actually tried another tube in it and still had the same issue.

    I have heard really great things about this pedal, but this is driving me nuts.

    I have one as my always on pedal. It boosts my signal quite a bit. How do you have your EQ set?

    happened to me once... changed the tube... and everything went to normal

    so change the tube and see what happens.

    So, finally got around to changing the tube. For the quick while that I got to test it (right before stage time) it seemed to resolve the issue.

    So.....like everyone said....just change the tube. Perhaps I had a hard time doing it because it was $23 for a 12Ax7 at guitar center. Better than a dead $300 pedal I suppose :)
