What is the series-parallel loop?
First, the effects loop is tube driven. When you run the loop in series, your signal goes directly from the preamp thru your effects unit and then into the poweramp. This is the easiest way to run effects units. The potential drawback is: the effect unit may color/degrade your tone and your tone will not be true. Running the loop in parallel allows a dry/uneffected signal to be mixed with an effected signal thru use of the mix control on the back panel. This allows you to blend the effects into your sound. Keep in mind if you use the parallel mode, you will need to run the “effect level” of your effect alot higher. Also, on all of our loops, your channel volume is the effect loop send level. If your signal is too hot, turn down the your channel volume and increase the master volume level, this is your poweramp return level. Also, most pedal effects work in the loop of the ECSTASY if your channel volume is about 10 o’clock or lower.
