    Bart's website came up with one wiring diagram that's too small to read. yay.
    I faxed them, since they don't have e-mail apparently, still waiting for a response.
    Talkbass search came up with one other guy asking for this about 2 years back with no luck.

    Anyone been able to dig anything up on this preamp? Even just pinouts would be very helpful so I can figure out what's what.
    :help:

    lots of googling just turned up a link to this PDF from a japanese website. It's not linked as a NTCT schematic from Bart's website.

    FWIW:

    Don't know about the Japanese thing but that is Bart's diagram whether it's linked or not and it used to be on their site if it's still not. That's probably 80% of what they had listed if not all of it. I've got the hard copies and it's the same stuff. You can figure out whatever you need from that. What happens a lot with those is the pre gets seperated from the mid unit and I've never seen a mid unit for sale alone. You can use that trim pot deal but I tried wiring one was a two band once (which I'd heard you could do) and I had no luck with it.

    I had one that came with the MTC mid unit, one without, and one with pot/mid unit that looked like a miniature nuclear power plant - worked like one too. Still have that reactor.

    It's on bart's site, so I assume it's their diagram. It isn't linked to from anywhere on their site that I could find, just floating in their webspace.
    It definitely appears that you need their little mid box to use it as a 3-band, but if you just bypass that section it'll work as a two-band. The guy I got it from (Luke Sheridan on TB) was using it perfectly well as a 2-band.

    Once I wire it up and test it I'll post a schematic for using it as a 2-band.

    I'd heard that but I tried everything I could think of and it's not like they're that many options. If you use that trim pot and caps it's essentially a two band cuase you don't have adjustment of the mids without gong into the control bay. The NTMB page has a list of resistor/cap values to change mids and I may have been able to rig a mid switch to vary mids onboard but I didn't mess with that.

    Whipped up a schematic bassed on the above listed PDF.
    here's how I'll be wiring. I'll check back in once it's done with an update.
