    I found some good information on trimming the N570 to help remove unwanted distortion. The chip contains to two identical sections which are mirrored on either side. Pin 3 and 14 provide an input for a control voltage for the gain cells. Pin 8 and 9 provide a distortion trim fro the gain cells. Not…

  • Termolo-Matic X

    This is the Tremolo-Matic X from Stompboxology. I’m in the process of building this for “Jonny” who I met at the last DIY Swap meet. He gave me this box to put it in.This project is coming together nicely.

  • Ugly Face for Steve

    Here’s an Ugly Face I built. I used PnP for the design on top. The transfer was a imperfect. But mostly worked. I’d really like to find a reliable toner transfer that works on these metal boxes.

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

  • LM386 Gain
