Klon BufferThis simple and effective buffer improves the high frequency degraded by long cables or pedal chains.
Enclosure and wiring Step 4 of 4
Place the assembled PCB and the rest of the elements (DC and 3.5 jack connectors, 9V battery clip, 3PDT foot switch, led...) in a metal enclosure. Connect the ground of the circuit to the enclosure in order to attenuate the noise (the GND of the input and output jacks are in contact with the enclosure). The following figures show the components mounted in the 1590A and 1590B enclosures.
For the wiring, use a 24 AWG stranded wire and connect all the elements as indicated in the following figure. No matter the order you follow to connect the ground (GND) as far as all the elements are connected. The led can be placed directly on the PCB. The figure shows the wiring with a negative tip DC connector (standardized Boss style 2.1 mm with a negative tip orientation).
