  • Page 2 SUMMARY The APIS FUZZ is inspired by the TMR Bumble Buzz, a knob-less octave-up fuzz using a phase splitter followed by a differential pair to emphasise the upper octave. It features an optical true bypass, allowing for a smaller DPDT footswitch with a click more subtle than with a common 3PDT footswitch.

  • Page 4: Build Steps

    Make sure the TLP222G photofet is properly oriented. The point on the photofet must be aligned with the point of its footprint on the PCB. Push the 2N2222 metal can transistors down firmly, but gently. They must not touch the PCB and should not be taller than the film capacitors. — APIS FUZZ (2021-06-30)
  • Page 5 Measure four wires of at least 3.5 cm length and strip off about five millimetres of insulation at each end. The wires should be as short as possible, yet long enough to leave some slack to make it easy to put the PCB into the enclosure. — APIS FUZZ (2021-06-30)
  • Page 6 Check the PCB for the orientation of the +9V and GND pads. Tighten the nut of the DC jack and solder the two wires to the PCB. The longer lug of the DC jack must connect to the +9V pad. — APIS FUZZ (2021-06-30)
  • Page 7 Make sure the PCB sits low enough so that no component is higher than the edge of the enclosure. It’s supposed to be a tight fit but there’s a 1-2 mm tolerance. CONGRATULATIONS! Give your new pedal a test drive. If everything works as expected, screw on the lid and you’re done. — APIS FUZZ (2021-06-30)

  • Page 9 Removing the LED from the build entirely requires soldering a solid wire in its place. The value of R should be changed to at most 2.4 kΩ — to account for power supplies down to 8.5 V and keep I at about 3 mA. — APIS FUZZ (2021-06-30)
