I've successfully tried all kinds of 12AX7 tubes
in both my regular 2101 and my 2101 Pro without any ill side effects. Yes,
your 2101 might sound different than another 2101 with the same or different
tubes, but who cares? As long as it sounds good to you.
For the purists, even the same 12AX7 tubes from
the same manufacturer can have different characteristics because of
manufacturing variances and can therefore sound different.
In short, listen with your ears. There's
nothing going to "blow up" in your 2101 just because you're using a 12AX7 that
has different characteristics than the ones that came "stock" with your new
unit. Go for it. Buy a few 12AX7 tubes from different manufacturers
and start swapping away.

It's confusing but it seems like many people are buying whatever tubes and putting them in and it works fine? I see that its possible that your 2101 might sound different from another 2101 by doing it this way (not necessarily bad?). If it means that slight gain adjustments might have to be made between units I might be able to live with that. I only really use my 2nd unit as a backup.
Does digitech still sell tubes for these?

How do you calibrate preamp tubes for the 2101?
