Super Hard On clone

I built this Super Hard On Booster a long time ago. I used one of those old DPDT switches without an LED. Later I wanted to add an LED I used R.G. Keen’s Millennium Bypass on a small piece of…

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…

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…

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…

MOSFET Boost Layout

Here’s a layout for the MosFET boost. The drawing is pretty sloppy. But this shows the schematic and layout I used for my build. Seemed to work well. Here’s a link to a picture of my build. Here’s a link…
