  • Flatline v1.1

    Flatline v1.1

    The first version of my Flatline PCB worked well but had a couple of small problems. Check out my original post for more information about the Flatline Compressor.  I fixed the issues with the original PCB, and had some boards made through PCBWay.com. The cost is only $5 for 10 boards, so it’s perfect for prototyping. The first […]

  • Flat Line by John Hollis

    Flat Line by John Hollis

    The Flatline is a compressor with a simple effective design. It works surprisingly well for its simplicity. I’ve built a few of these over the years on strip board. This time I decided to make my own printed circuit boards. Who is John Hollis? John Hollis was an early contributor to the DIY Pedal scene. […]

  • 1776 Bear Hug Compressor

    1776 Bear Hug Compressor

    It’s a compressor, might be a good one, I can’t tell. From what I here the best compressors are the ones that make you ask “is this thing on?” Easy build worked on the first test.

  • Compressor thing

    Here’s a my take on the LEDĀ  compressor thing. Really this is just a “mash up” of mictester’s “Really Cheap Compressor and the John Hollis Flatline compressor. You could look at this as the Flatline with a simplified LED driver. Or, the Really Cheap Compressor with a non-inverting amplifier stage. This hasn’t been tested. It […]

  • Flatline

    I had wanted build a compressor for a while now. But had never actually gotten around to actually making one. A few months ago I etched and soldered a a Saffron Squeeze, which is a Ross clone. Somehow I had not actually finished this before I found stripboard layout for John Hollis’ Flatline, which jumped […]
