S econd, you should set the effects in the loop so that it produces a 100% ‘wet’ signal. Some effects blend the signal from their input with the effected signal in such a way that the two are ‘out of phase’. That results in degradation of your tone. For example, when I use my old Boss DM-2 analog delay in a parallel effects loop, I set the “Echo” control for the delay length I want, I adjust the “Repeat Rate” to produce the number of echoes I want to hear after each note, and I set the “Intensity” control to maximum to provide a 100% wet signal. The controls on your effects will of course be labelled differently, but you get the idea.
