After experimenting with electronic music for a while I've come back to my guitar with a newfound interest in hardware effects specifically. I'd like to start building my own effects and was wondering if you guys knew of any good sites I should be checking out...sites with lots of articles and schematics are always nice but I'd particularly like to find someplace that has an active user community where ideas can be bounced around. After spending a few years kind of "away" from guitar (i.e. playing once in a while when the mood strikes but aside from that not really even looking at it) and working more with software synths and overall production I feel like for guitarists in particular there aren't a lot of options for people who want to experiment unless you've got an electrical engineering degree and all the required doodads for programming and flashing your own IC chips. I would really like to eventually develop some kind of intuitive, low-cost guitar synth that has lots of features but isn't super intimidating to figure out and doesn't require either a proprietary instrument or a MIDI pickup.
Also, do places still exist where you can get things like "grab bags" of a bunch of random mixed electronic components for dirt-cheap? Those were pretty much the best things ever.
