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…
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…
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…
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…
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.…
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…
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…
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.
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…
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.…
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…
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.
