  • Mold Spore Psycho-Scumatic Wah and Ring Modulator

    Mold Spore Psycho-Scumatic Wah and Ring Modulator

    Sounds like something from an old Bugs Bunny cartoon. Though it might have appeared in a Warner Bros. production it could have easily added to a sound track. Looks like it should be on the floor of your custom van, the one with custom paint and interior. This is the Snarling Dogs Mold Spore Psycho-Scumatic wah. We’ll…

  • Eagle PCB – Autorouter

    Obviously it would be great if a schematic would lay itself out. Eagle and other applications have included Autorouters, that do just this, for years. In the case of Eagle this was a feature you had to pay for. Until recently, well recently in years. Of course the computer in this case can not do…

  • Box of MOSFET

    Rock Box! I was talking to a friend about distortion boxes and the Box of Rock came up. Which got me thinking, I’d never heard one before, and Z Vex always makes good stuff. I found a schematic in the usual place. It looked like a pretty easy build. The Box is basically two pedals…

  • Ugly face with tone control

    The Ugly Face has an interesting set of options. The Threshold knob has to be the most interesting though least useful. Last year I thought I’d add a tone control in it’s place. I wanted to build an Ugly Face and keep it in 1590B sized box. This format makes it hard to fit more…

  • Breadboard test rig

    I had been meaning to make one these for a long time. Of course, like so many other things I managed to procrastinate on this simple but practical project for years. Well I finally got around to making the thing. I started with a length of aluminum L bracket from the hardware store. I had…

  • Octave Fuzz Take 2

    Here’s an updated version of the octave fuzz. Q1 and Q2 set up a basic NPN Fuzz Face type circuit. While Q3 acts as a phase splitter. Q4 and Q5 act as a frequency doubler each side being fed an inverted signal from Q3. So far the Fuzz section is working on the breadboard. The…

  • Switching Madness

    Mark Hammer on DIYStompboxes gave me the idea to add a momentary switch to a Ring Modulator. After thinking about this for a while I thought it be great to have both a momentary and bypass switches. The momentary switch would turn the effect on when when the effect was in bypass or turn the…

  • Axe-o-Matic

    Here’s a new drawing from the Stompbox Cookbook. This is a passive mid control. Could be a good alternative to the standard Guitar treble roll off type tone control. The pot should be a dual gang linear.

  • Distort-o-Matic VI

    I’ve been fascinated by the Stompboxology and Stompbox Cookbook projects for a long time. I’ve only built a few and many of the ideas are hit and miss. The concepts presented are compelling none the less. The Distort-o-matic VI for example, uses a very off the wall concept. The input signal is imposed on a…

  • Compressor thing

    Here’s a my take on the LED  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…

  • Tremolo-matic X redux

    After playing around with this for a while I find reducing the gain on the input stage seems to get rid of the harsh noise from a hot input. Not sure if this will work for every circumstance, but it did work for my guitar. To make up for the reduced output I modified the…

  • Clipping diodes

    This is the classic route to distortion. It seems to be included in many designs. Clipping diodes to ground have many different configurations and choices of diodes. Here’s a great thread talking about clipping diodes to ground. http://www.diystompboxes.com/smfforum/index.php?topic=82764.0
