Let me start off by saying that the guy who runs www.BuildYourOwnClone.com (henceforth known as BYOC), Keith, is pretty helpful. If you have any probs you can post to the support forum he has and he usually responds within a couple of days.

The instructions are pretty thorough, but if you're a electronics n00b like me just go slow and double check placement and value before soldering.

As far as orienting the transistors, the orientation page was pretty informative. I think all of his kits come with transistor sockets. The sockets only install one way so if you've installed the tranny wrong you just pull it out of the socket, change orientation and stick it back in the socket. Just make sure you don't solder the transistors in the sockets, just the sockets to the PCB.

AS far as the neg/pos on caps, on Keith's PCBs he marks the pos hole as square and neg are regular round holes.

I think the BYOC kits are great. They're an easy way for a person to test the waters of building DIY effects without all the hassle of chasing down all the parts, making printed circuit boards and drilling enclosures.

I've gotten hooked by the whole thing and found a great community of guys who know this stuff bigtime at www.diystompboxes.com/sboxforum/.
