Would any of you mind taking a second look at my BB Preamp layout? It's my first attempt at rolling my own. Only mods are diodes w/ switch and smoothing cap between pins 1 and 2.

2N5088 pinout is reversed. I'll have a closer look when i'm not on my phone. I'd also advise using black traces for ground, which is pretty standard and makes checking easier and quicker since it's what people are used to seeing.

Cool, thanks. I put this up on Reddit, too. This is the revised layout. The 5088s are still backwards though :oops: .
