Single parallel loop box with a mix control knob for wet/dry blend, and bypass switch, the Paraloop is designed for use in most amplifiers serial loops, i.e. in conjunction with the use of digital multi effect units so it's possible to maintain the guitars analogue tone without having it all digital converted in the effect unit, simply by running the effect unit all wet, then blend the effect in with the Paraloop's wet/dry control, the result is so much better than running the signal serial.
