Emerald Ring is designed to be an easy add-on to just about any Fuzz, or Gain circuit you wish to add an
Octave tone to. By driving the Emerald Ring with a Fuzz Face or other such as Angry Red Camel, Sriracha
Fuzz, Emexar ( Dist+) to result in much stronger octave/harmonics and less gating splatter.
Board Dimensions (W x H) 1.15" x 1.40" or 29 x 36 mm.
*Values should be precisely matched using a Digital Multimeter, in particular Capacitors, Use 1% Resistors for a closer
tolerance match. Capacitors have a wider tolerance, typically 5% to 20%.
** Silicon or germanium diodes will produce different sounds, with different circuits. Socket and See! If you have a DMM
or circuit, capable of matching the forward voltage, it is preferable to do so.

- Page 2 IMPORTANT NOTES ● Emerald Ring is designed to be an easy add-on to just about any Fuzz, or Gain circuit you wish to add an Octave tone to. By driving the Emerald Ring with a Fuzz Face [nice tonal variety] or other, such as Emexar 2 (Dist+), result in much stronger octave/harmonics and less gating splatter.
- Page 3 WIRING DIAGRAMS If you are building the Emerald Ring in its own enclosure, use this wiring diagram Use this for connecting Emerald Ring in series with another Fuzz or Distortion circuit.
- Page 4 Here is an alternate wiring scheme using a battery snap.. Be sure your In/Out Jack wiring is correct. A Stereo Jack (for battery use only) has a RING lug which is used to connect to the battery ground. If you do not intend to use a battery there is no need for a Stereo Jack.
- Page 5 For more versatility try our Easy Order Switching Boards, for switching the order of circuits, on the fly. This way you can have an Emerald Ring before Fuzz or after Fuzz in the same enclosure. Soldering Tutorial on Youtube Need a kit? Check out our authorized worldwide distributors: USA –...
