What tubes would be a good upgrade for a Mesa Basis M-2000

    Really happy with the M-2000 so far, but I am wondering what its capable of. Can anyone recommend upgrades to the stock tubes that come with it?

    Mad Sub experimented with this a while back. I forget what his results were, but it should show up in a search. I think he said Svets sounded really good. Or was those Sovteks? Hmmm. :oops: :confused: :p
  3. I put JJ teslas in mine and am really enjoying the thick natural compression they give in my m2k. The stock tubes were a bit limiting and just werent as musical as the tesla's. I tried the Sov 12ax7LPS and liked them but they just werent as lush as the tesla's. I also tried some GT's (I've heard they are relabeled Ruby's anyhow) and they were attrocious.

    I called Tim at MB about 2 years ago and he contended that changing the tubes in the m2k are ineffectual for one reason or another. That was disheartening, even tho I disagree. I hear noticable differences with changing out the tubes. YMMV
