Step 1: Parts List
1 x Guitar Hero X-Plorer Guitar Controller (with it's warranty prepared for departure)
1 x Phillips screw driver. I'm sure Phillip won't mind.
1 x Wire cutters/wire stripper
1 x strand of 26 gauge single conductor insulated copper wire. You might find this is some old phone wire or phone jacks.
1 x Hot glue gun with some glue sticks. (Hot glue is mandatory for this one)
1 x Drill with drill bit. Or a Dremel. Or a round file. Or something else that will make a 1/4" hole in the side of your beloved axe.
1 x Patience. Yeeeeeeaaaah. Just a little patience.
No solder option:
1 x Wire crimper
2 x small female disconnect spade terminals (need to find ones that will work with 26 gauge wire. I recommend finding some non-insulated ones for easier crushing.)
Things you'll need to buy if you don't have.
1 x Radio Shack Part# 274-0252 1/4" Mono Phono Jack. Panel mount, open circuit. UPC# 040293131401 (is a two pack in case you need to do two guitars or manage to lose/melt the first one) This will set you back about $3.
1 x Best Buy Lo Duca Universal Sustain Pedal Model# 3781 UPC# 013148037814. Of course you don't HAVE to buy this pedal but for $12 I think it's a good deal. Especially sense it has a polarity switch that allows you to step activate or lift activate. Meaning you can stomp this thing or lift your foot off of it to activate the switch.
