The Jeds Peds Bass Fuzz is a DIY effects pedal kit from UK maker Jeds Peds, built around the Bazz Fuss fuzz circuit. Jeds Peds calls it one of its "go to" beginner kits, and the maker says the PCB was specifically designed for an easy first build by a new builder. Despite the name, the maker notes it is not only a bass pedal: "Don't worry about it being called a 'Bass Fuzz' its definitely for guitar!"1
What the kit is and how it builds
The circuit is a fuzz with a single control. Jeds Peds describes the result plainly: "The resulting pedal is very good, the circuit is border line genius!"1
The build is deliberately simple. The PCB hangs beneath a 3PDT footswitch with the components sitting next to it, and the off board parts are the footswitch, jacks, 9v socket and LED. There is a little off board wiring to do to the single pot and also the jacks and power socket. The kit is supplied with an unpainted JP125B enclosure with top mounted jacks and power.1
The circuit uses one pot, and the kit does not include a knob unless you add one from the knob section when ordering. Jeds Peds suggests you get a big one.1
Versions and what each includes
Jeds Peds sells the Bass Fuzz in several versions, from a bare board to a finished pedal1:
| Version | What you get |
|---|---|
| PCB Only | Just the plain PCB |
| PCB & Components | PCB with parts |
| PCB & Components and off board parts | Adds footswitch, jacks, 9v socket, LED |
| Full Kit | Complete kit in the unpainted JP125B enclosure |
| Full Kit & Drilling | Full Kit with all the holes for a complete pedal, for a small surcharge |
| JP-Pro Kit | Full kit with a pre painted, drilled and UV printed enclosure |
| Pre Built Kit | Built for you, £25.00 GBP |
Drilling is an optional extra on the Full Kit rather than a separate product, and it covers all the holes needed for a complete pedal. The JP-Pro Kit removes the enclosure work entirely.1
The Pre Built Kit
If soldering is not for you, the Pre Built Kit is assembled by the maker. It is listed at £25.00 GBP, has a 1 to 4 week build time, and carries a 12 month repair warranty. No returns are accepted on pre built kits, but Jeds Peds says that should a fault develop, the maker will repair it.1
Where it sits
As a fuzz, the Bass Fuzz sits alongside other bass pedals and Jeds Peds' own ready made designs such as the Jeds Peds Super Sonic Bass Fuzz. Its Bazz Fuss heart is a one knob circuit, so it is a simpler proposition than a multi control fuzz, which is exactly what makes it a common first build1.
Questions
Is the Jeds Peds Bass Fuzz a kit or a finished pedal?
It is sold as a DIY guitar effects pedal kit, and Jeds Peds calls it one of its go to beginner kits. Most versions are for you to build yourself, from a plain PCB up to a Full Kit with drilling. There is also a Pre Built Kit, soldered and finished by the maker, which has a 1 to 4 week build time and a 12 month repair warranty with no returns accepted.
What circuit is the Jeds Peds Bass Fuzz based on?
Jeds Peds says the kit compares to the Bazz Fuss, a simple one knob fuzz design. The maker describes the resulting pedal as very good and calls the circuit border line genius. Despite the Bass Fuzz name, the maker notes it is definitely for guitar as well.
Does the Jeds Peds Bass Fuzz kit come with a knob?
No. The circuit uses a single pot, and you will need 1 knob for the kit. A knob is not included unless you add one from the knob section when ordering. Jeds Peds suggests getting a big one.
Is drilling included with the Jeds Peds Bass Fuzz kit?
Drilling is an optional extra on the Full Kit version, for a small surcharge. It covers all the holes needed for a complete pedal. The JP-Pro Kit goes further and includes a pre painted, drilled and UV printed enclosure, so no drilling is needed at all.
What is the difference between the Full Kit and the JP-Pro Kit?
The Full Kit gives you the PCB, components and off board parts in an unpainted JP125B enclosure that you drill and finish yourself. The JP-Pro Kit is the Full Kit with a pre painted, drilled and UV printed enclosure, so the enclosure work is done for you.
Is there a warranty on the pre built Jeds Peds Bass Fuzz?
Yes. The Pre Built Kit carries a 12 month repair warranty from Jeds Peds, so if a fault develops the maker will repair it. No returns are accepted on pre built kits. Pre Built Kits also have a 1 to 4 week build time before they ship.
