You don't have to buy any new stuff. Sound Sculputure Foot Sim has two effects loops.
These two loops are identical except that loop 1 is placed in the audio path before loop 2. In other words the two loops are wired in series. When these two loops are in the “bypass” state, then there is no connection between the effects and the audio path and the inputs to both effects are muted. When both loops are activated, then the audio signal passes from the selected instrument, through effect 1 first, then effect 2, then to the selected amp head. If only one loop is selected, then that effect is inserted only and the other effect remains unconnected and muted. To connect an effect, attach the “Send” from the HeadTrip to the input of the effect, and the “Return” to the output of the effect. If you are connecting a stereo effect, then only connect
one channel of the effect.
