Akula Posted May 17, 2009 Report Share Posted May 17, 2009 Hello, I'm looking into building a DIY piezo bridge for a project of mine, and I've become aware that I'll need a preamp, to prevent the classic squawky thin-sounding piezo situation. So I did a little googling, and after a very long search (first result), I found this web page here: http://www.scotthelmke.com/Mint-box-buffer.html My plan is to use the circuit explained there: http://www.scotthelmke.com/Mint-box-buffer-schematic.jpg But my bridge will have six piezo transducers, one underneath each saddle, and I'm planning to build a single preamp for each piezo. This will allow me to set the gain of each string's sound individually. I showed my plans to my dad, and he wondered what would happen when all the preamps are just connected together, such as this: http://img29.imageshack.us/img29/7379/piezopreamps.jpg (sorry for the huge size...) Any blindingly obvious error I've overlooked? 6 piezo's -> 6 preamps -> combined into 1 volume pot -> output... Cheers, Akula Quote Link to comment Share on other sites More sharing options...
