Step 3 Drill holes for new components and fitting the leds

Now it's time to start drilling ! This is probably the hardest part. You have to drill through solid steel, and Its pretty hard steel too. I strongly recommend a drill press for this, since it is more stable and powerful.

Lets start with the biggest hole: the one for the momentary switch. It has to be drilled right through the top surface of the pedal. The best spot to drill is probably between the 'A' and the 'I' (there's AMPLIFIER on the left and INSTRUMENT on the right). Grab a drill bit (i think it was 5 or 6 mm, can't remember actually. Measure the switch shaft to find out) and drill right through it. Don't rush, just drill gently with a firm amount of pressure on the drill bit.
Now take a slightly bigger drill bit, and use it to chip away some extra rubber around the hole. Don't drill into the metal this time. Now you have space to put the nut for the momentary switch. Press it in there, if it doesn't work, chip away some more rubber.
We're not going to place the momentary switch yet. You won't be able to wire it anymore if you do.

Now the side of the pedal. We need 3 holes: 2 3mm holes for the leds, and a hole for the miniswitch. I drilled them next to the output and the DC in. Check out the picture below. Put the switch through the hole and screw on the nut.

Now, lets fit the leds. Grab one, and just force it into the hole. You can also use special led holders, these require slightly bigger holes. Then put a small drop of superglue on the led and wah casing (at the inside!). Wait 2 minutes and your done, these leds won't be going anywhere!
