    I would like to buy this nice preamp because it sounds.. well, awesome!
    But first i need to know what tubes it uses and what the approximate tube life expectancy is of these tubes.
    If these tubes aren’t commonly available and the tube-life is low it makes no sense for me to buy the pedal, that’s why i ask these questions.

    Specs and info here: https://www.ehx.com/products/lpb-2ube

    (2) 12AX7WB tubes. How often they need changed depends on your usage. If you’re using a lot you might want to change every 6 months or so. Normal use probably a year.

    Thanks for your answers!
    Oops, i indeed could have found the tube specs myself. Sorry for that.
    What does WB mean? The only 12AX7WB tubes i can find are from Sovtek, doesn’t EHX have them in their lineup? Or does the EHX normal 12AX7 also fit?

    You say six to twelve months, but what’s the lifetime in hours? I mean, using them a lot or normal can mean something totally different for you than it is for me.
    (i won’t use the pedal for distortion, but for warming up my synth sounds)

    From the EH catalog:
    The Sovtek 12AX7WB has more gain and saturation than our WA. Its warmer, darker sound is preferred by Rivera, VHT, Demeter, and Kendrick, among other manufacturers.

    You can use any 12AX7 tube in it. The WB suffix is for low noise.

    There is no set standard that I’m aware of on how often tubes should be changed. Basically, when it starts sounding different or tired. That;s when you change them. You might actually be fine for years.
