2026-GPX-JSA-Effects-Fuzztronought-Main-700.jpg

This was the second pedal I picked up from JSA Effects at the recent Leeds Pedal Show - and it’s even better for me than the already exceptional LNS Overdrive Modded OD-1 that I rushed to the stand to secure!

 

On the day of the show I came away with just those two JSA pedals. I later secured one of Blue FX’s oddly shaped Pillux Fuzzes, and should really have picked up a Holy Island Spectral Fire at the same time - which I also sorted out post-haste - shortly after the show! Those two pedals ...

2026-GPX-Rockwright-Fuzzmaphobia-700.jpg

This goes back to a demo that my good friend Pedal Experiments’ Phil did back in October of 2024 (2nd one below) - of the smallsound/BigSound Blarg o-tron o-tron.

 

He was in contact with Lucas from Rockwright around about the same time - they got to discussing the circuit, and decided to collaborate on an evolved compact edition of that circuit - which is what became the Phuzzmaphobia.

 

They weren’t the first to evolve the Blarg o-tron o-tron as the now alas defunct Dominican Republic’s ...

2026-GPX-Klowra-Vires-Isolated-Power-Supply-V2-700.jpg

The Vires is a high quality construction, beautifully made pro slimline mains-powered pedalboard power supply - which sits in between the CIOKS SOL and DC7 with its 6 ports, but mostly targets NUX’s 5-Port Zeus JR - delivering one further outlet than that for the same price of $129.

 

This is one of those power supplies very evidently designed for sitting on the underside of most pedalboard types. It is the main base unit - like all those other supplies just mentioned. While other brands have...

2026-GPX-Catalinbread-Clean-Little-Secret-700.jpg

What we have here is essentially a downward and sideways extension of the DLS Series - first with the lower-gain Clean Little Series compact edition - more akin to a BluesBreaker. And then a Mini version of the original DLS - the Little Secret - which contains just the dual-Mu Preamp section of the Dirty Little Secret - without the EQ’s.

 

All three of these are available current at a launch discount - and all these pedals are widely available now at international dealers - including all the ...

2026-GPX-Cioks-DC7-and-SOL-Retro-Editions-700.jpg

I’m a little late on this one! I did kind of clock these when they were first teased (October 2025!) but only very briefly and in passing - and then quite promptly forgot about them. Where I really love CIOKS Future Power Generation Power Supplies - but I don’t really have much need for these too variants - and I’m not really about shelf-ware.

 

I personally use 2 x 8’s and a 4 - and have always felt that CIOKS should reissue their DC10 as a Future Power Generation Supply - but they’ve not ...

2026-GPX-Asheville-Analoger-APH-12-Phaser-700.jpg

This project has long been on the cards, as I’ve always intended to take the Asheville Music Tools journey - the Analog Modulations in particular. The Phaser ended up being the first on the list, and I will tackle the Flanger next, and then the Chorus / Vibrato after that.

 

I’m not short of a great Phaser or two - as the APH-12 is the 29th phaser in my reference collection (full list after the demos below). I have a soft spot for so many of these - including the Beetronics Larva, Caroline ...

One of my favourite super-versatile overdrives get a new edition / makeover - to bring it up to date with the latest design phase of Colortone Pedals. The Parasite gets its name from the definition of its unique JFETs - which are described as ’... sizzling with parasitic feedback’.

 

4 JFETs make up the core soundstage - which is further served by wide ranging Active Post-Drive Low and High EQ’s, as well as the super smart Pre-Drive Bright Boost and Bass Boost stitches - where the latter is ...

Caroline Guitar Co's Arigato 4-Stage Analog OTA Phaser + Vibrato + Vibe is a beautifully executed multi-modulator

2025-GPX-Caroline-Guitar-Co-Arigator-Phaser-700.jpg

I originally featured this pedal on the site back in January of 2023 - so it’s been on the cards for a while! I obviously need to juggle a lot of priorities all the time - and some pedals unfortunately fall through the cracks momentarily - while I mostly manage to recover them at a later stage!

 

This Arigato is my 4th Caroline pedal, and I love it so much that I’m very tempted to pick up Philippe’s other 2 modulations - the Parabola Tremolo, and Somersault Lo-Fi Modulator / Chorus.

2026-GPX-ThorpyFX-Kudu-Overdrive-Main-700.jpg

The Kudu is a really cool circuit developed by Dan Coggins as a smart multi-clipping tone-enhancer - created to make everything it touches sound better. Thorpy and Dan have run the pedal into a vast array of pedals and amps - and the pedal never fails to improve the texture and tonality of the device that it pushes.

 

There’s no less than 12 Diodes onboard - while 6 of those are for power management. Which leaves 2 x 2N4148 Silicon Diodes for Soft Clipping, 2 x Red LED’s for Hard Clipping, ...

Empress Effects' new Amp-Like Drive Pedal is a super-versatile Extended Gain-Range Active-EQ Saturator with Pre or Post Boost, and a built-in Noise Gate

2026-GPX-Empress-Drive-Main-700.jpg

I really rate both the Empress Germ Drive and Multidrive pedals, and have had both Heavy and Heavy Menace pedals from the start. According to the Empress Drive introduction the development path for this new Drive pedal started with patching a Germ Drive into the middle of a Heavy Menace circuit!

 

Furthermore, on first glance - there seem to be some parallels to the ParaEQ II too, and indeed Zak tells me that the ParaEQ was an inspiration also - and was in fact used to help set the core ...
