MODULATION EFFECTS

The main characteristic of the modulation effect (see example) is to add and/or lay other wave forms to the signal.
This kind of effect should be used in the  loop effect of your amp, that is between the Premaplifier and the Power
amp.

SYNTHESIS EFFECTS

The main characteristic of the synsthesis effect (see example) is to modify the signal wave form. (i.e. the
distortion effects).
This kind of effect should be used between the guitar and the input of your amp, in a standard connection chain.

SERIAL LOOP

In a Serial Loop all the output signal coming from the Preamp passes throught the effect. In this case on your
effect unit it is necessary to adjust the balance between the DIRECT (DRY) and the EFFECT( WET).

PARALLEL LOOP

In a Parallel Loop only a part of the direct sound passes throught the loop effect, without going out from the
Send. This part of the signal will be mixed with the signal that comes from the Return.
In this connection the quality of the effect is not so important as it is in the Serial Loop connection, because the
Direct will be kept by the loop (see drawing).
