  • Uber Drive #2

    Uber Drive #2

    Second build of the “Uber Drive”. This is clone of Paul Cochran’s Timmy overdrive. Maybe this needs a better name? I manufactured these boards over at PCBWay.com. Their prototyping service gives you 10 boards for $5. Which is a great deal. It also left me with a few boards to spare so I thought I […]

  • Rock Box

    Rock Box

    The Box of Rock is a great Marshall sound in a pedal. It includes a boost section also. Box of Rock is pretty amazing and sounds great. J. Mascis likes it so much that he had Zvex put two in one enclosure. But what if you wanted something more like an Orange amp? Here’s an […]

  • Timmy clone

    Timmy clone

    Timmy is a boutique overdrive by Paul Cochrane. This pedal generated a lot of discussion over the ethics of cloning pedals. A couple companies were accused of cloning Timmy. Most of the most popular boutique pedals out today are clones of something. In the case of Timmy, Paul is a small manufacturer, who does all of […]

  • The Crank by Mark Hammer

    The Crank by Mark Hammer

    This is interesting variation on the Tube Screamer style diode clipping. Read more about it at Mark Hammers site here: https://hammer.ampage.org/files/The_Crank.gif In a nutshell the goal seems to be less distortion. More of a booster to overdrive effect. I’d say this circuit meets that goal. The sound is mostly clean with some gravel or grit […]

  • UBE Screamer 4069

    UBE Screamer 4069

    I wanted to do something a little more artful as a box. The Joy Division’s Unknown Pleasures has a very iconic image. I don’t know what the secret sauce of this image is but it’s very compelling. From what I read the image appeared in Scientific American 1971 and was described as “stacked plot” of […]

    Smash Drive is a DIY community project by Aron Nelson, who runs the DIYStomboxes.com forum. Smash Drive is a overdrive/distortion built from the LM386. Its simple and easy to work with. you’ll find the 386 in many guitar circuits. its cheap and easy to get. Projects that use the LM386 RunOffGroove Ruby Earth Quaker Devices […]

  • 6 new PCBs from PCBWay

    6 new PCBs from PCBWay

    I got 6 new boards made at PCBWay.com. The PCBWay.com service is a great deal the biggest cost is shipping. The best deal is to order multiple boards at once since the shipping is combined. This time I waited til I had 6 boards designed and ready to go before ordering. As long as your […]

  • Vulcan 1.2

    Vulcan 1.2

    I made a couple small updates to the first Vulcan PCB. Got the new boards and did a build to confirm they are working as expected. Everything works as it should! This is a pretty good sounding overdrive distortion. The best part is the ability to clean up the sound by rolling off the volume. […]

  • UBE Screamer 4069

    UBE Screamer 4069

    This is a version of the UBE Screamer using the 4069 in place of the 4049. Essentially these chips are the same. They both contain 6 inverters. The 4049 is a 16 pin DIP while the 4069 is a 14 pin DIP. Electrically the should the same but the pin arrangement is different. The original […]

  • Another fail!

    Here is a UBE Screamer with blend knob. I left a resistor out of the mixer and mixed up the Blend and Gain labels.

  • UBE Screamer v2

    UBE Screamer v2

    I made an update to the RunOffGroove UBE Screamer from a suggestion in their notes. This version adds a mix control the blends some of the original signal with the distorted signal. The original uses Rx to set a fixed mix amount. The notes suggest a value of 100K to 470K for this resistor with […]

  • 1981 Inventions DRV clone.

    1981 Inventions DRV clone.

    Here’s a PedalPCB Informant. This is mostly the Rat circuit with a few changes. The biggest change is the addition of a charge pump. The charge pump provides a +9 and -9 volts power for the circuit to run off. Effectively this doubles the voltage. I have some reservations about the power supply. The clipping […]
