Make sure you don’t get glue on the front side of the microphone car-

tridge, or it could interfere with any sound coming through.

10. Use another cable tie to secure the wires from the microphone to one
    of the dowels.

Mounting switches and more on the box........................................

It’s time to drill all kinds of holes and pop various components into the box.

Follow these steps to do so:

1. Drill holes in the box where you will mount the potentiometer,
   audio jacks, headphone jack, clamp, and on/off switch, as shown in
   Figure 6-16.

We put the on/off switch and potentiometer on one side of the box, the

headphone jack on the opposite side of the box, and the phono jacks on

the bottom of the box.

We kept the headphone jack to one side to keep the output signal from

feeding into the input of the circuit (for example, by being near the

microphone wires), which could cause feedback.
