Make a footswitch, become a monkey.

Step 2 Make a trash strain relief

Let me just say this, do the right thing and buy a proper Heyco strain relief. I threw this quickly together for the sake of time. While it works for now, it may become hazardous with usage.

Obligatory Warning: You may be risking injury or property loss by using this trash mod. But here's what I did:

Drill a hole in the cap the same dia. as the power cord.
Insert the power cord into the cap then mount it to the box.
Set it to the proper length inside the box giving yourself enough wire.
Pull the cap and cord back out and measure the length of the cord from the end to the bottom of the cap.
Pull more length of cord through and put a zip tie to the length you measured.
Clip off the excess zip tie and pull back the cord in the cap until the zip tie bottoms out in the cap.
Partially fill the cap with hot glue until the zip tie is fully covered.
Put the cap/cord back into the J Box tightly securing it with glue.
