Build of a 1 channel looper switcher

Build of a 1 channel looper switcher

Today we see the basic approach to build a true-bypass 1-channel looper / switcher (analog - non-programmable). First of all, what is the true-bypass looper / switcher for? This pedal can be used in two ways:

1. Make "buffered" pedals of true-bypass type(reduction of signal loss in the chain of effects);

2. Insert in a loop a series of pedals that can be activated and deactivated by means of a single switch (that of the looper / switcher).

Our looper / switcher KIT, contains:

List of tools required for assembly (not included in the KIT):

  •   Soldering iron and solder tin;
  •    Drill and bits of suitable size for drilling aluminum boxes;
  •   Scissors and pliers;
  •    Star screwdriver;
  •    9V power supply for effect pedals;
  •   Tester (recommended for debugging but not strictly necessary).

If you are not familiar with the use of the welder, I suggest you follow some tutorials that you can easily find on youtube.

Assembly procedure:

1. Check that the contents of the kit received coincide with the material listed above;

2. Drill the aluminum box according to your preferences (the components can be mounted horizontally or vertically);

3. Assemble the different components with the aluminum box as shown in the figure according to the preference layout, vertical or horizontal (seen from the underside of the aluminum box);

4. Preheat the soldering iron and proceed with the connection of the different elements following the diagram below:

5. Close the aluminum box using the cover and the 4 screws provided in the KIT;

6. Connect the pedal to a 9V power supply;

7. Connect the input guitar (IN), the output amplifier (OUT), the IN of the pedal with buffer on the Send and the output of the pedal with buffer on the Return.
