The IDC Direct-Linc FX is a hand held direct contact ITC device. It uses your body as the antennae for reception. It is available as a Random or Linear Scan, although I recommend Random. The Direct-Linc FX comes with a pre-set IDC Effects Echo/Reverb, the same FX I use in the larger IDC 2K series IDC boxes the IDC Direct-Linc FXWC, and the IDC Direct-Linc Choice FX.
