Best gear to connect spring reverb into line-level patchbay?

    I have a very nice spring reverb that I use between my guitar and my guitar amp. I would like to connect it to my studio patchbays and use it during mixdown.

    It is a tube buffered unit...........to be specific, a Dumblelator-type circuit with the reverb hard-wired into its effects loop.

    My studio (Pro Tools HD, mixer, rack units) runs at +4 line level, so I have the impedance mis-match problem. So, I need:
    (1) A Reamp type of unit on the input, to convert from low impedance to high impedance.
    (2) A unit on the output, to convert back to low impedance and to amplify the signal back up to line level. Note: I may not need much amplification if any, since the unit has three level controls (main signal, effects loop send, and effects loop return).

    I am looking for quality units, but I can't afford to spend a lot on gear that is dedicated to a single reverb. For example, I can't afford a high end preamp with DI to put on the output.

    What two units would be good buys for this application?

    Here's one combination I found:
    - Radial J-Iso for input to reverb ($260)
    - Radial J+4 for output from reverb ($200)

    Try just wiring it in...

    Keep the send down very low and as you don't need a lot of 'verb on the return usually, the lowered output may be fine.

    You won't damage anything, and you may get lucky.

    I have tried it, and I got distortion and what sounded like artifacts, due to the impedance mis-match I assume.

    It's probably a level thing, vs. impedance.

    Impedance mismatches usually just cause changes to frequency response/levels.

    I used to patch a Sansamp and DLS Echo pedals into the FX loops of the console at the studio and it worked just fine, using appropriate adapter cables.

    I like to use the MW-1 for these situations.

    On the low end, I believe Ebtech makes level shifting boxes. You could also scour ebay for old level matching transformers. I got a box full of mil spec 10K:1M audio transformers for $20 once.
