Key Points

Stonegate FX’s The Figure Filter Fuzz: two fully parametric filters — Mid 1–4 kHz and High 9–14 kHz — each with ± cut/boost and internal Q trimmers (Narrow→Wide). Surface controls: Fuzz Output (into the filters) and Master Volume.

Circuit notes and hardware: op‑amp + transistor gain mix, transformer pickup simulator, top‑mounted jacks, mechanical true bypass, matte black enclosure with UV artwork, internal LED brightness control, Lumberg power jack, Switchcraft/Lumberg audio jacks, Vimex/Alpha pots, Alpha footswitch, gold‑plated PCB, Power 9V DC [-] 50mA.

Cosmetics/UX: labels hard to read and no top‑surface branding. As of 2026-07-13, the price was £295 CAD / $212 USD.

Stonegate FX is a new brand to me, seems like it’s been around for a while as there are 6 pedals on its roster - where this The Figure Filter Fuzz is the most intriguing one by far!

I features 2 fully parametric filters - which it calls Mid and High, while they’re really Highs and ’Air’ essentially. With the first one covering 1kHz to 4 kHz, while the second targets 9kHz to 14kHz - which is super high!

We then have 2 level controls - a Fuzz Output - i.e. the Fuzz level going into the Filters, and then the overall Master Volume output at the end. The Full Parametric Filter nature - means you have ± Cut / Boost for each of those Frequency Filters, along with internal corresponding ± Bandwidth Trimmers - which range Narrow CCW and Wide CW.

Looking at the internals this seems to be a mix of opamp and transistor in terms of the gain generation, just a single visible transistor in the circuit. You can also see the transformer pickup simulator - which makes this pedal very versatile within your pedalboard - and give you freedom of placement!

I have a few filter fuzzes in my collection already, and this would surely be another interesting addition. It’s the most attractive and appealing of the Stonegate FX pedals to date - with that cool artwork and twin coloured aluminium knobs. I might have been tempted to use Cyan knobs closer to the lighter blue colour rather than the lavender ones - but they still look pretty cool.

A couple of points I can’t help but focus on - firstly the legibility of the labels / legends - which is pretty much tantamount to invisible. And secondly the lack of surface branding! All pedals should have at least an ident on the top visible surface to identify them - as that is the most visible side - the one that shows up in pedalboard photos etc. If you see that pedal as is top-down, in the most common viewport - you would have no idea as to what brand or pedal model this was. Those details are on the front edge - which is not visible from the more typical playing positions - and certainly not visible by the audience.

Pedal brands need to realise the level of competition they are up against - where instant recall and recognition is critical for long-term success. At first glance here you don’t really have a clue as to whose pedal you’re looking at!

Surface Controls - Upper Mids Filter : 1kHz-4kHz, Highs Filter 9kHz-14kHz, Fuzz Output Level, ± Upper Mids Cut/Boost, ± Highs Cut/Boost, Master Volume.

Internal Trimmers - Q Controls Narrow > Wide for Upper Mids and Highs Filters.

There’s much to like here, but room for some refinements too. My ’Key Criteria’ article sets out my view on Pedal Branding in general. I would of course like to see Stonegate FX succeed. This pedal could do really well for them, especially if prospects can easily identify it from afar!
