    So, what comes closest to that preamp that the Motown studio used for all them famous recordings?

    Broughton P15.

    I love mine. Could not be more happy.

    Motown used a passive DI called the Wolfbox, designed by an engineer named Ed Wolfram. The plans are available online, they are easy to build and sound amazing. The transformers, however, are hard to find and expensive when you do find them.

  5. Since most of the tracks were recorded on a B15, I'll chime in with the Broughton P15 as well.

    I'd much rather have the P15 than the DI below.


    This DI's meant to be an accurate repro of the original Motown DIs...
    Motown D.I.
    Motown DI - anyone try it yet?


    However, as the guy in the vid above points out, you won't get the Jamerson sound out of the DI.

    You won't get the Jamerson sound because it was in his hands, not the DI. The Acme box is indeed expensive, but apart from the transformer the rest of the components are cheap. I built my own for about $100.00 and used it on this record:

    On top of that I believe that they didn't DI Jamerson. I read somewhere that it was a miked Ampeg B-15 through what I believe was a Focusrite compressor.

  9. Broughton P15 is the correct answer.

    No, they weren't. All the electric bass and guitars were recorded thru a in-house built direct box, which is what the Acme is based on.

    Bassically, Michael

  11. Thanks for the clarification.

    What about the B15 then?
    It's not like they had 24 or 48 tracks back then to play with so unlikely they were double-tracking the bass through an in-house DI and an amp, yet there persists info floating about the inter-ethers that the B15 was the amp used in the vast majority of hit-making studios from that era.

    This was what was used on all the Motown recordings. No tube. I've wanted one for a while. I think @DirtyDuke actually got one at some point.

    I love the P-15 and there is no doubt it will cop the Motown sound but to my knowledge Jamerson and Dunn mainly used those Acme style DIs rather than a B-15.

    He played one live. It's been discussed ad nauseam.

    The Real James Jamerson Amp

    this thread has all the info. very early 60's was b15 but after that it was all this homebrew Tube DI to the board, no amp.

    i'd say acme motown DI to get that transformer saturation, then a Universal Audio LA-610 to get that tube warmth preamp sound. That would probably be closest for me.

    In my readings it seems they were very concerned with ambient sound in the room during those motown recording sessions, so anything that could be recorded DI was. I've read multiple accounts that they only had one single speaker as monitor for all the DI instruments.

    This is what they used in studio

    Then this was created

    Then they ran out of Urie transformers and one of the fellows that had a hand in designing this bailed and the other stayed and created the green "Motown DI" we have today.

    Which in my opinion doesn't sound nearly as good as a P-15.

    UTC and Triad Transformers not UREI. the broughton has nothing to do with the motown unit. the motown unit did not have an EQ, had an input and output tranny (broughton just 1), did not use an 6SL7 tube, and further more was wired at unity gain.

    furthermore bob olhsson and others (ed wolfrum) have said for jamerson they put him on a fairchild compressor (more tubes and transformers) and pultec eq (more tubes and transformers). babbit they said had a more aggresive sound so no compressor, maybe a little pultec.

    the signal chain is filled with massive transformers and lots of tubes, broughton has 1 of each. not even close.
