→Effects Loops
A ''parallel'' effects loop features a mix control, using the same logic as individual effects - you can determine the mix of dry, where the pre-amp signal goes straight from pre-amp to power amp, and wet, the signal processed by all your effects in the loop. 100% mix is identical to a serial effects loop, while 0% is like using no effects loop at all. The big benefit of a parallel loop is when you use effects without mix controls, which was typically the case with vintage effects.
What you have to watch out for with a parallel loop is when effects introduce lag into the signal, such as with some digital effects that necessarily , by nature, buffer the signal time-wise. Even a small lag in the signal will create a ''comb filter'' with the dry signal, where regular nulls occur throughout the frequency spectrum, particularly in the highs. The tone will sound dull or not as full as it should. Also, effects like tremolo or others that alter volume may sound quite awkward when blended with a dry signal.
