Can someone check this over for me?

Hi, I built a layout in PCB Express for a Big Muff, with the goal being to fit it inside a Hammond 1590B. It will fit, but I was hoping another set of eyes could check it out for me to see if I missed anything. I based it off the Big Muff Pi layout from Tonepad. Thanks a lot.

by no means a proper answer to your question, but...

that red side is the top copper layer. if you're sending these boards to be made, you may want to change that.

Looks ok, however, I dont like a thin trace going from Q4 all the way across to the C10 and in such proximity to the 9V power trace. Noise?

You know its always better to try and build one o nthe PCB u designed before ordering a large quantity...

Otherwise good and compact looking, perhaps I suggest that the 9V red trace could be run Across those three blue traces above the board, by eliminating that portion of the 9V trace and using a jumper wire to reroute it so it's not close and parallel to anything.

everyone seems to experiment with the diodes.
2, 3, 4 or more.
So it might be nice to have room for 4, 2 in each direction and with enough room around them to use leds instead of diodes and a big enough copper pad so that they can be solder/unsoldered without lifting the copper from the board

For that I've [on perf ofo course but...]
used two pads [for structural stability/strength] and a couple...'staple shaped' [doubled over, or just 'double footprinted' a 'copper nail' to solder to] wires sticking out of the board to hook diodes or other parts to, this prevents having to mess about desoldering with the copper parts of the bottom of the board, and allows changing components from the top of the board...it may have some limitations or drawbacks, but I like it in some cases.

Could you clarify a bit please? Sorry, I'm new at this.
