I used this when I got my board. I thought it was really helpful.
Here's another one I did, out of boredom. Last board for the night. View attachment 63051



Should the whole string be elsewhere? I was just responding to the OP...
The only thing that I have as a gripe with this tool, is the PS mounting. So I've had to mount the PS's on top to where I want them under the boards.
You could always position the PS where is would approximately be underneath and put what's over it on top. My PS is underneath the MXR EQ in the picture above (it's completely hidden).
