    Has anyone played through one of the Ampeg SVT heads made in Japan by MTI in the 80's? If you have I would like to know what you thought of it. Did you like the sound?

    MTI SVT’s were made between 1980 and 1986 and are easily identified by their black face, white rocker switches along the top, medal corners, and the enclosure doesn’t slant back at the control surface like that of the SVT-CL SVT-HD, and SVT’s of the 70’s.

    I've got one. I think it sounds good and sounds like an SVT, but I've never side-by-sided it with an older one to see what the difference really is. But the point is, just playing through it, it seems to do everything one would expect an SVT to do, just fine.

    I've used it with several different cabinets, but just recently I (finally) picked up a fridge for it. Whoa buddy!

    I believe I've read that the 80's Japanese MTI STV is exactly the same as the 70's US SVT internally. I think they used all the same components and even the same circuit boards. I've seen them and the chassis looks the same - same controls, jacks, tube positions etc. in the same spots. I may have read that at some point in production they designed out the hard to find 12BH7 tube. I think that's it.
    I read that for their initial runs they simply built them from american parts they received from Ampeg when they bought the name.
    Other than the control panel printing and the cabinet, I believe MTI didn't make any significant changes.
    SLM did significantly redesign it when they bought Ampeg but I think they did a good job and improved the amp.
    I've never played thru one but there's some SVT gurus on TB that probably have.

  4. MTI's use different transformers and put out slightly less power than old US SVT's, but their build quality is superior.

    They had a rep for spotty quality back in the day............ Good general build quality, sometimes bad parts or mistakes.

    I'd bet any still around have been fixed if they had a problem originally.

    Good amps, although many have the "12AX7 mod" instead of the 12DW7, same as SLM units.

    I used one on a gig about a month ago, and it was outstanding.
