The Jeds Peds Super Sonic Bass Fuzz is a one-knob fuzz aimed at bass players, sold by the UK kit maker Jeds Peds as either a DIY kit or a pre-built pedal. The circuit is based on the Meat Head, modified for bass guitar, and it sits in the maker's One Knob Fuzz range of single-control fuzzes1. If you are browsing the wider field, it belongs alongside other bass pedals and the fuzz family generally.
What it does to your sound
Jeds Peds describes the modification plainly: "Its a modified Meat Head with huge input and output caps allowing a lot of bass into the mix!"1 In practice, those large input and output capacitors are what set it apart from a standard Meat Head-style fuzz: they keep the low end from being filtered out before and after the fuzz stage, which is the usual reason plain guitar fuzzes can sound thin on bass. The maker also notes that although it is named a Bass Fuzz, "it works brilliantly on guitar too"1, so it can pull double duty on a board that serves both instruments.
Jeds Peds is careful to frame the lineage honestly: the pedal is a slightly modified version of the Meat Head to suit bass guitar, with no endorsement or approval from any manufacturer, and that information is for comparison only1.
Buying it: kit or pre-built
The Super Sonic Bass Fuzz is offered two ways, and the terms differ between them:
- DIY kit: supplied with a JP1590B enclosure; the builder will need 1 knob for the pedal. A build guide is available, with build guide V2 as the current version and an older build guide also available1.
- Pre-built: listed at £27.00 GBP, with a 12 month repair warranty, so should a fault develop the maker will repair it1.
Jeds Peds states there are no returns accepted on pre-built kits. The 12 month repair warranty is the cover that applies instead1.
For players who want a related but differently voiced option from the same maker, the Jeds Peds Bass Fuzz is the other bass fuzz in the lineup.
Questions
Does the Jeds Peds Super Sonic Bass Fuzz come as a kit?
Yes. Jeds Peds sells the Super Sonic Bass Fuzz as a DIY kit, and also offers it pre-built. The kit is supplied with a JP1590B enclosure, and the builder will need one knob for the finished pedal. A build guide is available, with a V2 guide as the current version and an older guide also on hand. Pre-built units carry a 12 month repair warranty, but no returns are accepted on them.
Can the Super Sonic Bass Fuzz be used on guitar?
Yes. Jeds Peds says that although it is named a Bass Fuzz, it works brilliantly on guitar too. The circuit is a modified Meat Head with large input and output capacitors that let a lot of bass into the mix, so guitar players get a full, low-heavy fuzz rather than a thin one.
What enclosure does the kit use?
The kit is supplied with a JP1590B enclosure, which is Jeds Peds' own 1590B-format box. That is the standard small pedal enclosure size, so it fits a normal pedalboard footprint.
Can pre-built Jeds Peds kits be returned?
No. Jeds Peds states that no returns are accepted on pre-built kits. Instead, the maker gives a 12 month repair warranty, so if a fault develops the builder or owner can send it back for repair.
What is the One Knob Fuzz range?
The One Knob Fuzz range is Jeds Peds' line of single-control fuzz pedals, and the Super Sonic Bass Fuzz is part of it. Each pedal in the range uses one knob, keeping the controls minimal, and the Super Sonic Bass Fuzz is the bass-oriented take on that format.
