This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

VooDoo Lab Sparkle Drive

The Sparkle Drive is a very versatile drive pedal, offering everything from clean boost to full on dirty Tube Screamer tones. The Clean blend allows you to layer both clean and dirty sounds (kind of like playing through two amps, one clean and the other dirty). One of these has lived on my pedal board for the last 4 years and it sounds great for both guitar and bass.



A common mod to this circuit is adding some clipping options. On the PCB I've added 2 extra pads right above the "Gain 2, Gain 3" pads. These will allow you to use an on/off/on DPDT switch to go between which ever diode combination you want. The most common combination seems to be the stock 1N4148s and red LEDs. The center "off" position of the switch will remove the diodes altogether. See lvlark's vero layout for the switch diagram.

    I've just finished building this and the layout is missing a trace/connection between NE5532N pin-6/1k resistor and 13.3k/100k resistor.

      Thanks for catching that! The layout has been updated.

    Hey buddy! Long time without posting here and doing pedals for myself, but I got around building this. You can tag it!

    Hi.
    There are resistances with values that are not normal. What are the real values? I guess it will be the closest value. It is right?
