The Jed's Pedals 1590a Green Ringer kit is a do-it-yourself pedal kit that builds an octave-up effect, the kind of circuit that rings a note out one octave above the one you play. Jed's Pedals puts it plainly: "Insane octave up is what this is all about." The kit is built around the Green Ringer design and compares to the Dan Armstrong Green Ringer and the EQD Tentacle, a comparison the maker offers for reference only, with no endorsement or approval from any manufacturer1.
If you are new to octave effects, they sit apart from the overdrive, distortion and fuzz pedals on a board: instead of adding grit, they generate a new note. You can read more about the type on the Octave & Pitch Pedals page, or see the assembled version of this circuit on the Jed's Pedals Green Ringer kit page.
The kit options
The kit is sold in four versions, so you can buy as much or as little of the build as you want1:
| Version | What you get |
|---|---|
| PCB Only | Just the plain PCB |
| PCB & Components | PCB, onboard components and any pots and toggle switches |
| Full Kit | As above, with an undrilled JP1590a enclosure and off board components: foot switch, jacks, 9V, LED |
| Full Kit & Drilling | As above, with drilling as an optional extra for a small surcharge |
Drilling includes all the holes for a complete pedal, so the Full Kit & Drilling option saves you from laying out and drilling the enclosure yourself1.
The Full Kit's enclosure is undrilled as standard. If you do not want to drill your own enclosure, the drilling option carries a small surcharge1.
Controls and tone shaping
The circuit needs a single knob. Jed's Pedals' guidance is direct: "You will need 1 knob for this kit. I suggest you get a big one."1
The kit also departs from a stock Green Ringer layout in one way that affects the sound. Adam Richards of Jed's Pedals explains1:
"Our kit has an additional pot in place of a fixed resistor. The pot is a worthy addition and removes a bit"1
That added pot gives you a tone control over the output, trimming the edge that the Green Ringer design is known for1.

Questions
What does the Jed's Pedals Green Ringer kit sound like?
It is an octave-up effect. Jed's Pedals describes the circuit as delivering an insane octave up, which is the whole point of the Green Ringer design: it rings out a note one octave above what you play. The kit also adds a pot in place of a fixed resistor that the maker says removes a bit of the shrillness from the output tone.
Is the Jed's Pedals Green Ringer kit pre-drilled?
Not as standard. The Full Kit is supplied with an undrilled JP1590a enclosure, and drilling is an optional extra with a small surcharge. If you add the drilling option, it includes all the holes needed for a complete pedal, so you do not have to lay out and drill the enclosure yourself.
What comes in the Full Kit?
The Full Kit includes everything in the PCB & Components option, which is the PCB, onboard components and any pots and toggle switches, plus an undrilled JP1590a enclosure and the off board components: the foot switch, jacks, 9V connection and LED. Drilling the enclosure is an optional extra with a small surcharge.
How many knobs does the Green Ringer kit need?
One. Jed's Pedals says you will need 1 knob for this kit and suggests getting a big one. The single control works with the kit's added pot, which sits in place of a fixed resistor and shapes the output tone.
What is the Dan Armstrong Green Ringer?
The Dan Armstrong Green Ringer is the circuit this kit compares to, along with the EarthQuaker Devices Tentacle. Jed's Pedals notes the comparison is for reference only, with no endorsement or approval from any manufacturer. The Green Ringer is an octave-up effect, which is what the Jed's Pedals kit recreates.
