www.execpc.com/~fdeck/bass Here it is, the design information for my BBBB -- Bare Bones Bass Blender. It is a complete solid-state bass preamp, more or less inspired by the Raven Labs Professional Master Blender. The dirty secret of DIY design is that you make up a "reason" for doing it, after it is already done. For the DIY'er, GAS takes the form of building new gadgets. My reasons were twofold. First, I found myself sitting down at the computer to unwind, every night after putting the kids to bed. Designing a preamp seemed like more fun than surfing the web. Second, I have an irrational compulsion to understand exactly how my gear works, and I learn by doing. At present, I have no intention to commercialize this design. If enough people are interested, I would be happy to order a small collection of bare printed circuit boards. More than anything else, I welcome all comments and criticism.
