    Bobtavia by Bob Starr

    Bobtavia is an old-school DIY octave fuzz. It’s a lot like the Roger Meyer Octavia but uses an LM386 instead of transistors. The Bobtavia uses a transformer like the original Octavia and the Maestro Brassmaster. What’s nice about the Bobtavia is its simplicity. The whole circuit is just a handful of parts.  This was one of the first […]

The Ugly Face is more of a synthesizer than fuzz pedal. It produces square output from the input guitar signal. You can […]

  • LM386 Gain

    I’ve playing around with the 386 Audio Amplifier. This is a really great chip. It has a lot of possibilities. Looking at all of the great circuits that use this I’ve noticed there are many different ways to set the gain. Gain is set using pins 1 and 8. With these two pins open the […]
