     Radial Revolutionizes the Lunchbox
      The Workhorse™ is a lunchbox frame that
incorporates full mixing capabilities to a stereo bus,
monitor output and headphones. It features 8 slots
that are backward compatible to previous API
formats while adding greater I/O connectivity.
      According to Radial lead engineer Kevin Burgin:
“While researching this project, we looked at all of the
current rack-frame lunch-boxes and found that they
all fell short: All they do is provide power for the
modules and 48V phantom for mic preamps. We felt
that for $1000, it just did not add up to real value. So
we took the initiative to redesign the concept and                         WORKHORSE MASTER OUTPUT                                          CARD SLOT-8         CARD SLOT-7         CARD SLOT-6         CARD SLOT-5          CARD SLOT-4        CARD SLOT-3          CARD SLOT-2          CARD SLOT-1

                  Dream Theater Records w/ Radial JD7
                    “On our latest CD, "Black Clouds and Silver Linings", I used a secret weapon for the first time in Dream

              Theater's 25 years together. Peter Janis at Radial lent me a JD7 in the studio and it turned out to be a really
              important recording tool. At times I wasn't sure which Boogie amp would be the best one for the job, so by going
              into the JD7 and recording the direct guitar sound at the same time as the mic'd amp sound, our engineer Paul
              Northfield and I were able to go back at our leisure and re-amp my performance through various rigs. That way,
              we were able to choose one sound or the other, or a combination of the two, or alternate between amps
              throughout the song without me having to replay the guitar parts. I even added wah-wah performances to some
              of the tracks while the recorded track was replaying through the amp! The Radial JD7 proved to be a real asset
              during the recording process and the best part was that my tone and the guitar's response remained true when
              plugging into the box. I purchased the JD7 from Radial after the record was done.”
