I've built various kits from BYOC and GGG and I've always had a good time putting them together. I want to start modding and designing a few pedal for fun, but I have no idea where to start. I can't read schematics and I know very little about electronic components. Does anyone have advice on how to get started? There's various books on amazon, but the review always vary and I wouldn't want something I'm not going to learn from. Thanks.
