Aron's Forum - One of the best forums on the net with hugely knowledgeable members. Dont ask me any questions, ask the board. You will get a far more polite and accurate response.
Francisco Pena's Site - One of the neatest clone PCB sites. Buy his boards, they are great.
JD Sleeps Site - Another great clone and DIY design site. Buy his boards, buy his pedals.
Free Stompboxes Forum - A relatively new forum without the ethics that bind the komraderie of Aron's forum. But, on the plus side. You might get a booteekers pedal schematic.
Alex Petrini's Site - Another great clone and DIY site. A few of my projects are hosted on this site. Highlights include a zvex probe workalike.
Analog Guru's Site - A site with some correct and incorrect schematics. Includes booteekers.
Smallbear - A resource for electronic components. A bit pricey for the run of the mill components. However great for discontinued and rare components. Excellent Customer service.
R.G. Keens Site - A huge disorganised effects knowledge resource. Everything from how to measure Hfe of Germanium transistors accurately to a Tychobrahe parapedal clone.
