Orange Squeezer +++/fullwave compact PCB layout - please check

[DC9V]

While I was waiting for my missing components to arrive (dealer forgot to ship about a quarter of the ordered parts ) I started to muse on my next projects.
I decided to build an Orange Squeezer +++. I did a search for a PCB layout and I found Nelson's, unfortunately it was too big to fit in a 1590B box. So I decided to try to do a more compact layout with DIYLC. Here's the result:



Since the OS+++ was reported to have a little treble loss I added Jack Orman's Stupidly Wonderful Tone Control 2 to add a bit of treble boost.

Can someone please check this layout? This is my first serious layout and don't know much about PCB drawing dos and don'ts, so corrections/improvements/explanations are welcome.

Anyone tried it?

I love how one of the SIX pots  is optional on this squeezer!

Yeah, and normally it has only one pot But the way it is shown here, it's very versatile, I think.
