Now all we need is a picture with that gorgeous tube lit in the dark!
What tube did you use and just how much does it light up? 
Lot of bass content, seems usable for bass maybe?
All in all, very nice build, congrats 
Thank you. I used a 12AU7.
12xx7's don't really light up much no matter what circuit they're in. But if you like to play in the dark, then you will be able to see a tiny little glow in there. But seriously, it's the sound of these things that matter. My best 6L6's (NOS RCA's) has black glass housings. Can't see anything in there no, but the sound! Simply amazing.
I haven't tried it with a bass yet. Will do. good idea.

Wow, both of those pedals look awesome, great work!
What did you use to cut a hole large enough for the tube in the enclosure?
I used a reamer to cut the hole. Reamers are excellent if you have a steady hand. You just bore a little pilot hole and then off you go. Just be sure to stop and check from time to time so that you don't go to far.
Nice build Niopren. Care to share your layout with us ?
Edit: I've done some tests running the circuit at 12V.
Disclaimer: These are my subjective opinions!

12AU7: Brand, Tube Amp Doctor. Nice muddy overdrive and sparkling clean tones. Lots of bass content. Has some nice compression.
12AT7: Brand, Tube Amp Doctor. Very nice overdrive. More distorted. A bit more sparkle on clean tones. Less bass content.A little bit more "open" sound with some more midrange. This particular tube sound better than the AU7 in terms of the quality of the overdrive. Where the AU7 sounds like a perfect tube for a blues horn this particular AT7 seems like a better choice for guitar.
12AX7: Brand, Electro Harmonix. Low output. Less gain than the AT7. This tube has been used for about a year. Probably time to discard it.
Conclusion: For that warm and cozy fireside jam, I'd go for the 12AU7. This one drips of honey and makes me want to grab a beer and play harmonica! For everything else I'd use a 12AT7. But that's just me.
