    Comments about Radial Engineering EXTC 500 Reamp Guitar Effects Interface:

    The device is great for using any guitar pedals on a recorded track. Even if someone uses plugins, we all know the real TS- 9 sounds awesome and can be used with EXTC 500 on a dry track, guitar, bass, even vocal.
    The EXTC 500 might be used as a reamp, (in this case use only Send jack and plug the other side into you favorite amp).
    The similar one is Radial X-Amp, which only does reamping.

    Overall, Great product from Radial, Great service from MusiciansFriends.
