I heard that the Radial JDI can be used backwards as a re-amping device?
Yes this is true. The Radial JDI, when driven ‘backwards’, will also reverse the impedance from low-Z to hi-Z and allow a padded down line level to drive the amp at a 10k-ohm level. The difference however is akin to comparing a passive direct box to an active direct box or like comparing a dynamic mic to a condenser. Active boxes tend to have more ‘reach’ or better high frequency transfer of upper harmonic detail.
