  • 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…

  • Super Hard On – OSH Park

    Super Hard On – OSH Park

    Three Super Hard On’s built from PCBs from OSH Park. This layout was compact and well arranged. Off board pads were all arranged in a row on one edge, I used four conductor ribbon cable for neat wiring. The ribbon cable I have I got at Radio Shack, some years ago, it’s solid core, with…

  • ZVex Distortron

    ZVex Distortron

    I was thinking about building one of these myself, then I saw this used on Reverb.com for $99 and free shipping. I was hard to beat. The effort to build it woul been worth $99.

  • 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…

  • Sycophant

    Here’s my take on the SHO. With crackle free knob. Adjust the value of C3 to create a range boost.

  • MosFET Range boost

    Here’s a simple idea that you will work on almost every transistor circuit out there. We’ll apply it to the MosFET boost here. Remember the gain of the MosFET boost was determined by the Drain and Source resistors. For the example circuit, as the Source resistor decreases in value the gain increases. A capacitor acts…

  • MosFET Gain

    Here’s a typical MosFET boost. The gain is roughly determined by the ratio of Drain and Source resistors. Divide the Drain resistor (Rd) by the Source resistor (Rs) to find the gain. For example if Rd = 5k and Rs = 5k the gain is 1. Use a Pot for Rs to set variable gain.…

  • MosFet Range Booster

    Here’s a quick idea for a MosFet Range Booster.

  • MOSFET Boost

    This is Jack Orman’s MosFET Boost. This was an easy build. It sounds good, great clean boost with a lot of gain.
