Effect loop on the amp

If your amplifier is suitable for it, you can also connect your effects via "send" and "receive". Now it may seem that it doesn't really make a difference, but it certainly isn't. Your amplifier consists of a preamp with a power amplifier coupled behind it. These are usually located in the same box with the loudspeaker integrated in case of a combo.

Effects placed between the "send" and "return" terminals through the amp will be placed between the pre- and power amp sections. Not every effect is in place here and will still be placed in front of the amplifier. An equalizer, delay or reverb are generally good for connecting to the effect loop. It may be that these give a better result.

In practice it can therefore mean that some of the effects for the amplifier are connected, as shown in the figure above. And that other effects are placed between the preamp and power amplifier via the "send" and "return" terminals. The final picture may then look like this:

* "Stemapparaat" = a Guitar tuner
** Vervorming"= Distortion

In the case of my Koch Studiotone, that would mean that pedals could be linked between the "From FX-out" and the "To FX-in" jacks on the back of the cabinet.
