Can I run my Line 6 Modelling pedal in a parallel or series FX loop?
Line 6 does not support the use of any Line 6 Four Button modeling pedal in an effect loop as the Line 6 Modeling pedals are designed for instrument level (guitar/bass output) to be inserted between the instrument and the amplifier. The signal strength of a line level signal (i.e. an effect loop) can cause the input buffers to fail.
