anyone here have any knowledge (websites, books, material resources) on building guitar/bass/synth/vox effects boxes/stomp boxes? i'd gladly appreciate some input directly from people who are into making music and/or know about building circuits.

i'm also interested in learning about this - i don't know much that could help, though. i've only seen websites that have instructions for slightly modifying effects or copying effects. anyone have any radical ideas about building new effects?

I build my own stuff. I work in electronics, so this sort of stuff is second nature. I take it you have some knowledge of electronics. You will need some basic tools as well.
i.e. soldering iron, solder, (know how to solder) cutters, pliers (big and small), wirestrippers screwdrivers, drill, hacksaw. etc. you should know your resistors from transistors and be willing to make mistakes and for stuff not to work.
get a multimeter which can measure. volts, ohms and miliiamps. if you can afford it, get one which can do capacitance and transistors and maybe even frequency.
if you can get access to an oscilloscope, that would be very handy.
feel free to ask me any questions.
look for Electronic Projects for Musicians by craig anderton.

get this book it should have everything you need to know to start off. its simple. no midi. guitar orientated slightly, but great book.

heres one to get you started:
a ring modulator..... with a twist. It requires no power. it is totally passive. you will need: two audio transformers (1:1 ratio small ones) link either one in the link is fine. 4 GERMANIUM diodes. I beleive this doens't work with silicon ones, although have never tried it (something to try this weekend) try to look for OA90 or OA91 diodes. again these are small and should be easy to find.
finally 3 jack sockets to plug in your inputs. a full schematic is found here: http://www.synthfool.com/ringmod.html the site doesn't mention it, but you can tie the two inputs together and make a frequency doubler. This is used a lot in RF design but I have tried it and it works rather well.
Its an old design, and appears in a lot of places, but now could be superseded by a double balanced modulator chip(for audio at least), but its much easier to do this way. And hopefully it will work for you!

you dont wanna goto that ucapps thing. that is COMPLEX. embedded systems, etc. very hi tech stuff. seriously.
START SIMPLE. start with the passive ring mod or something. then something which runs of batterys. then make a powersupply and somehting else then make more stuff and learn electronics. learn how to make PCBs learn about embeddded systems/PICs/CPUs THEN goto that site and build those projects.
