Flattley Pedals has officially announced the release of the JK Fuzz, a boutique silicon-based stompbox that marries the iconic grit of the 1960s with modern engineering reliability. Part of the prestigious “Platinum Range,” this pedal aims to solve the historical headaches of vintage fuzz circuits while retaining their legendary soul.
Modern Logic Meets Vintage Grit
For decades, guitarists have wrestled with “Fuzz Face” style circuits, which famously require being first in the signal chain and often behave unpredictably with other gear. Flattley’s JK Fuzz disrupts this tradition by incorporating an integrated input buffer. This allows players to place the pedal anywhere on their board without losing the signature response of the silicon transistors.
The pedal isn’t just a clone; it’s a tool for tone-sculpting.
Beyond the standard Volume and Fuzz dials, Flattley has added a PreDrive control and a Bright control. These additions allow users to manipulate the frequency response both before and after the signal hits the fuzz stage, offering a range from thick, doom-heavy walls of sound to thin, 1960s-style “fizzy” psychedelic tones.

Premium Aesthetics and Tour-Ready Features
As with all Flattley Platinum Range pedals, the JK Fuzz is hand-processed in Flattley’s dedicated paint shop. It features:
-
The Red Halo Light Ring: A signature design choice that diffuses light when the effect is engaged, preventing the “blinding LED” syndrome on dark stages.
-
Custom Hardware: 20mm red anodized aluminum etched knobs and a matching aluminum foot topper for a larger contact area during high-energy performances.
-
UK Craftsmanship: Every unit is handmade and hand-wired in the UK using premium-grade components.
Technical Specifications & Controls
| Control | Function |
| Volume | Adjusts output levels; can act as a clean boost for solos. |
| Fuzz | Dictates the gain intensity; highly interactive with the PreDrive setting. |
| Bright | A passive post-distortion control to tame treble or remove bass frequencies. |
| PreDrive | Adjusts input frequency before distortion; boosts bass or thins the signal. |
| Power | 9V DC external power only (no internal battery option). |

Frequently Asked Questions (FAQ)
Can I use the JK Fuzz after a wah pedal?
Yes. Unlike vintage fuzzes that “choke” when placed after a buffered pedal or a wah, the JK Fuzz’s internal buffer ensures consistent behavior regardless of its position in your signal chain.
How does the PreDrive control affect the sound?
The PreDrive acts as a gatekeeper for your guitar’s signal. Cranking it clockwise pushes more bass into the circuit for a modern, heavy fuzz. Turning it down thins the signal for that classic vintage “bite.”
Does it take batteries?
No. To maintain its compact footprint and high-quality internal wiring, the JK Fuzz operates exclusively on an external 9-volt power supply.
What makes the Platinum Range different?
Platinum Range pedals undergo a more intensive hand-finishing process in the paint shop, resulting in a unique, high-end aesthetic that differs from standard production models.

The Verdict
The Pros:
-
Placement Freedom: The input buffer is a game-changer for complex pedalboards.
-
Tone Versatility: The PreDrive and Bright controls offer far more variety than a standard two-knob fuzz.
-
Build Quality: Exceptional UK hand-wired construction and stunning aesthetics.
The Cons:
-
Power: No battery option may be a slight inconvenience for vintage purists.
Final Thoughts:
The Flattley JK Fuzz is a masterclass in boutique evolution. It successfully captures the unpredictable magic of 1960s silicon fuzz while stripping away the technical frustrations. If you are looking for a “forever” fuzz that looks as good as it sounds, this is it.
Price: £259
