    Stone Bender #2

    This pedal sounds so good I had to make another! Check out my first build and the build page. I manufactured these boards at PCBWay.com. This board is posted at the PCBWay Shared service. You can order and build it for  I milled a gray powder-coated enclosure. It looked better than I was expecting. It’s got a […]

    Silicon Tone Bender

    Here is a Silicon Tone Bender built around four BC109 transistors. It sounds pretty good! The original circuit was provided by user Mic Tester over at FreeStomboxes.org. I built this some years ago on a piece of strip board. I ended up selling it at the Musicians Electronics Swap meet in Berkeley. Here are some […]

  • Silicon Tone Bender take 2

    Whenever I build something I usually build two. The parts are cheap. If I make a mistake or the PCB doesn’t etch correctly I have a spare. If you build the first and it doesn’t work you can build the second and compare the two. In the case of the Silicon Tone Bender I used […]

These sounded good and have that metal can with a little tab mojo. I used a ceramic .1µf cap for the input cap and skipped the […]
