Great Eastern FX Focus Fuzz Deluxe

The Great Eastern FX Focus Fuzz Deluxe is a limited-run fuzz pedal built in Cambridge, UK by Great Eastern FX, the company founded by David Greaves. It is an evolution of the 2023 limited edition Focus Fuzz, and its "deluxe" status comes from what was added: boost, overdrive and octave functions on top of the original fuzz circuit¹.

A three-way rotary switch selects Boost, Drive or Fuzz, and a second footswitch applies a transistor-based analog octave-up overtone on top of whichever mode is running². The whole thing is built on a through-hole board inside a gold hammertone-finish enclosure with skirted knobs, weighing a reassuring 650g¹³.

Fuzz, drive and boost with an octave overtone

The Focus Fuzz Deluxe covers three gain modes plus the octave, all from one box⁵²³:

• Boost: Guitar.com's reviewer found it can be deployed as a clean boost with quite a lot of added output available, while Guitar Pedal X described a beautiful subtle grit, adjacent to a dirty boost¹⁴.
• Drive: Guitar Pedal X found the overdrive reaches well into fuzzy-drive territory but can also be very classically overdrive-y; Guitar.com's reviewer heard too much fuzzy fluffiness for a conventional overdrive, a tonally neutral medium-gain crunch¹⁴.
• Fuzz: Guitar Pedal X described a full Fuzz Face sear, beautifully textured but immaculately behaved and expansively tweakable⁴.
• Octave/Overtone: A second footswitch applies a transistor-based analog octave-up². Premier Guitar's reviewer found it adds buzzing, fractured and ringing overtones without stripping low end from the signal, and called the octave function "a star" that is more musical than many octave-up effects, keeping chords full and detailed³.

The octave is not limited to fuzz mode. Premier Guitar's reviewer confirmed "It works with the fuzz, drive, or boost"³, and Guitar Pedal X found the octave and overtone works beautifully with the boost and overdrive modes too⁴. Premier Guitar's reviewer found that adding the octave to boosted signals with a generous heap of focus input yields funky, eccentric electric-sitar tones³.

A practical detail Premier Guitar highlighted: the output level differences between fuzz, drive and boost are pretty uniform, so quick mode switches on the fly will not cause an ear-frying level jump³.

The controls

The pedal carries three knobs, a three-way rotary mode switch and two footswitches⁴².

The Focus control is the pedal's signature, inherited from the original Focus Fuzz, where it was designed to push the guitar firmly to the front of the mix⁸. It works in all three modes: Guitar.com's reviewer notes that in both non-fuzz modes the knob is also adding gain to the front of the circuit¹.

Guitar Pedal X pointed out an unusual interplay: it is the only fuzz that reviewer knows of where you can turn down any two of the three knobs and still get interesting outputs⁴.

Inside the circuit: germanium and silicon transistors

The Deluxe replaces the all-silicon circuitry of the standard Focus Fuzz with the mixed silicon and germanium transistors of the original 2023 limited edition¹. MusicRadar describes it as a hybrid silicon-germanium circuit with an NOS germanium transistor under the hood², and Premier Guitar identifies that fuzzy heart as a Soviet-era germanium transistor that is tricky to source³. That scarcity is what limits production.

Guitar Pedal X broke the circuit down by section⁴:

The fuzz circuit is nigh identical to the original Focus Fuzz's two-transistor hybrid core⁴. The octave section's BC107B and BC177B pairing is what Guitar Pedal X credits for uniquely warm and musical harmonic octave overtones⁴. The circuit is executed on through-hole board, and Premier Guitar praised the robust pots and switches and the pedal's considerable heft³.

History: from the 250-unit Focus Fuzz to a 400-unit Deluxe

The original Focus Fuzz launched in March 2023 as the third pedal from Great Eastern, following the Small Speaker Overdrive and Design-A-Drive¹⁹. It was marketed as the fuzz for people who don't like fuzz, aimed at convincing players who never got on with fuzz that it was a viable pedalboard option, working with single-coil and humbucker guitars alike²¹⁰. Production was limited to 250 units because Greaves only had parts enough for that many, with the MP38A germanium transistors particularly hard to get hold of⁴⁹. All 250 sold soon after launch¹¹.

The all-silicon Focus Fuzz Silicon followed in July 2023 as a darker, grittier and more affordable version built on the silicon side of the original circuit¹¹¹². The Focus Fuzz Deluxe, launched in March 2025, returns to the hybrid germanium-silicon design and expands it with the boost, overdrive and octave circuits⁴². Greaves estimated he had enough transistors for 400 Deluxe units³, matching the 400 units planned at launch⁴.

What reviewers said

Reviews were positive across the board. Guitar.com's Richard Purvis summed up his verdict as "Great fuzz sounds, great drive sounds, great boost sounds"¹, and Guitar.com's 2026 fuzz buying guide named it the best combined fuzz and overdrive in that category, crediting it with nailing prized Tone Bender sounds while also serving as a medium-gain overdrive or clean boost⁶. Guitar Pedal X gave it a Silver award in the site's 2025 fuzz roundup⁵.

On the Tone Bender question, Guitar.com's reviewer found that "with the focus control at minimum, it's very close indeed to the classic Tone Bender MkII sound"¹. Interestingly, the same site's 2023 review of the original Focus Fuzz concluded that pedal was not really a Fuzz Face or Tone Bender in overall voicing, but an altogether more modern-voiced pedal than expected¹³.

The main criticism was price. MusicRadar's reviewer framed it as three or four pedals in one², and Premier Guitar's reviewer noted it is hard to imagine adding extra footswitches without sacrificing the pedal's basic elegance and proportions and elevating the already considerable price³.
