The Jeds Peds Double Trem is a stereo harmonic tremolo, sold as a DIY guitar effects pedal kit by the UK kit maker Jeds Peds1. Harmonic tremolo is a variation on the standard tremolo effect: where an ordinary tremolo pedal sways the whole signal's volume, a harmonic tremolo works in stereo, which is why the Double Trem uses a 4PDT footswitch for its stereo switching. Jeds Peds notes on the product page that this is a first for the maker's kits: "Because its stereo it uses a 4PDT as well, which I think is a first for me here"1.
Kit and build options
The Double Trem is sold in six versions, so you can take on as much of the build as you want. At one end, the PCB Only option is just the plain circuit board; at the other, the Pre Built Kit arrives assembled by Jeds Peds1.
| Version | What you get |
|---|---|
| PCB Only | Just the plain PCB1 |
| PCB & Components | PCB, onboard components and any pots and toggle switches1 |
| PCB & Components and off board parts | As above, plus off board components: foot switch, jacks, 9v socket, LED1 |
| Full Kit | As above, with an undrilled enclosure1 |
| Full Kit & Drilling | The drilled enclosure with all the holes for a complete pedal1 |
| Pre Built Kit | Built for you, with a 1 to 4 week build time1 |
A couple of build details are worth knowing before you order. The board is spaced for PCB mounted toggles and pots, which keeps the wiring inside the enclosure tidier than hand-wired off-board parts1. And because the pedal is stereo, the footswitch is a 4PDT type rather than the 3PDT found on most mono DIY kits1.
Pre Built Kits have a 1 to 4 week build time, and Jeds Peds does not accept returns on them. The maker instead gives a 12 month repair warranty: "There are no returns accepted on these but I do give a 12 month repair warranty so should a fault be developed I will re[pair it]"1.
Questions
Is the Jeds Peds Double Trem a kit or a finished pedal?
Both. Jeds Peds sells the Double Trem as a DIY guitar effects pedal kit, and also offers a Pre Built Kit that the maker assembles for you. The pre-built option carries a 1 to 4 week build time, and it comes with a 12 month repair warranty, though no returns are accepted on pre-built units.
What enclosure does the Jeds Peds Double Trem fit?
The Double Trem fits in one of Jeds Peds' JP1590BB cases. If you buy the Full Kit you get an undrilled enclosure and drill it yourself, while the Full Kit & Drilling option arrives with all the holes already drilled for a complete pedal.
How long does a pre-built Jeds Peds Double Trem take?
Jeds Peds states that Pre Built Kits have a 1 to 4 week build time, so the pedal is assembled to order rather than shipped from stock.
Does the pre-built Double Trem come with a warranty?
Yes. Pre-built kits carry a 12 month repair warranty from Jeds Peds, so if a fault develops the maker will repair it. Returns are not accepted on pre-built kits.
Why does the Double Trem use a 4PDT footswitch?
Because the Double Trem is a stereo pedal, it needs a 4PDT footswitch to handle stereo switching. Jeds Peds notes on the product page that this is a first for the maker's kits.
