The Jeds Peds Foggy Twin is a dual-channel distortion that the maker calls "a posh distortion plus" built around both halves of an op-amp chip, with a three-way clipping selector on each side1. It is based, according to Jeds Peds, on "a now discontinued dual distortion pedal, thats grey with an A and has two channels"1, and the maker notes that "this kit compares to the EQD Gray Channel"1. It is sold either as a DIY project or as a pre-built pedal made to order.
Clipping options on each side of the chip
The Foggy Twin's two channels are not identical. Each half of the chip has its own toggle switch with three positions, and the two sides offer different clipping types1:
| Side of the chip | Clipping options |
|---|---|
| One half | Silicon, Germanium, No clipping1 |
| The other half | LED, JFET, No clipping1 |
Silicon and germanium diodes clip in the familiar hard-edged ways players know from distortion pedals and fuzz pedals, LED clipping is a softer, more open form of hard clipping, and JFET clipping is a softer still, tube-flavored option. The no-clipping position on each side lets that half of the chip run clean, so the pedal can work as a boost or clean gain stage on one channel while the other clips1.
Kit or pre-built
Jeds Peds sells the Foggy Twin in four DIY forms plus a built option1:
- PCB Only: just the plain PCB1
- PCB & Components: PCB, onboard components and any pots and toggle switches1
- Full Kit: as above with an undrilled enclosure and off-board components (foot switch, jacks, 9V, LED)1
- Full Kit & Drilling: full kit with drilled enclosure1
- Pre Built: a pre-built kit made to order, with no knobs1
The kit comes with a JP1590BB enclosure1. You will need two knobs for the kit, and the maker suggests medium sized ones1.
The pre-built option arrives without knobs, and Jeds Peds states that no returns are accepted on it. The maker does offer "a 12 month warranty though so if it develops a fault then please get in touch"1.
Questions
What is the Jeds Peds Foggy Twin based on?
Jeds Peds describes the Foggy Twin as based on a now discontinued dual distortion pedal that is grey with an A on it and has two channels. The maker also notes that the kit compares to the EQD Gray Channel, which is offered as a comparison point rather than a claim about the circuit's origin.
Is the Foggy Twin a kit or a finished pedal?
It is available both ways. Jeds Peds sells it as a PCB only, a PCB with components, a full kit with an undrilled enclosure and off-board parts, a full kit with a drilled enclosure, and a pre-built unit made to order. The pre-built version arrives without knobs and cannot be returned.
What clipping options does each side of the Foggy Twin have?
Each half of the chip has its own three-way clipping selector. One side offers silicon, germanium and no clipping. The other offers LED, JFET and no clipping. That gives the two channels different clipping palettes.
How much does the Foggy Twin cost?
The maker's product page lists the Foggy Twin at £65.00 as of October 2026. The price is given in pounds sterling because Jeds Peds is a UK maker.
Does the pre-built Foggy Twin come with a warranty?
Yes. Jeds Peds offers a 12 month warranty on pre-built items, so if the pedal develops a fault the maker asks buyers to get in touch.
What enclosure does the Foggy Twin kit use?
The kit comes with a JP1590BB enclosure. The full kit version supplies it undrilled, and the Full Kit & Drilling version supplies it already drilled.
