I put this together tonight. Won't have chance to play loud until Thursday, but having had a knock around through a practice amp for 20 minutes I'm feeling pretty thrilled about it!
I did try mounting the power supply on the bottom, because the board is designed with that in mind, but it wasn't working for me.
It doesn't look as bare as I feared it might, and to be honest I'm clumsy enough that having the pedals a couple of inches apart will definitely make my life easier. I kept hitting two pedals at once by mistake on my old board.
I'm not dead set on the layout, and I may end up reordering the signal chain (chorus after dirt, perhaps?), but right now it goes:
Boss DD3 > TC Electronic Sub 'n' Up (replacing my Mooer Pure Octave which shit the bed) > TC Electronic June 60 > TC Electronic Eyemaster > Electro-Harmonix Silencer > Tomsline Black Teeth > Behringer TU300
Also planning to add a second DD3, replace the Black Teeth with a proper RAT (haven't had any problems with it in almost 2 years but it feels flimsy so I don't trust it), and possibly add a Big Muff into the mix. The PWT80 is only designed to power 8 pedals, but I thiiink I could just daisy chain a couple of the less power hungry ones if I needed 9 (can anyone confirm/deny?). I'm also tempted to experiment with the Silencer's effects loop at some point.
