I thought I should focus on my large format heavy-hitters for a change - where these 8 are some of my largest, most potent, and best favoured gain pedals. They are arranged here in alphabetical order, while they were released in the below chronological order. All 8 have featured heavily in my rig at different times - and all 8 are still very valid award winners and still in rotation. While the enormous girth of the Elektron Analog Drive means that is gets somewhat less of a rotation nowadays - ...

My second longest mission is now complete as I have 3 fantastic enhancements and evolutions of the OD-1 circuit and one intriguing adjacent

2026-GPX-Boss-OD-1-Variants-700.jpg

If you read my recent PastFX OG-1 piece - you would know that I initially intended to pick up an original long-dash OD-1 with the very original 14-pin JRC3403 OpAmp onboard. There’s hardly any of those available in the wild - and typically they are battered and way over-priced. I had intended to get one and have it modified with an additional tone-stack - as I always felt that was a key element missing from the original, and one of the reasons for the greater success of the Ibanez TS808 Tube ...

Verlie has outdone herself once more - with 3 more killer takes on notable vintage effects - utilising the same rarified components as those originals.

 

For her Klon take - she has removed a number of previously core circuit elements which can otherwise generate excess noise for some players. In removing those trouble-making parts - she has delivered an utterly unique take on the Klon - which she further enhances with 2-Band EQ, and an extra Presence switch. It has the usual Buffered Bypass ...

Celebrating Ritual Devices' Flagship Etched Series Quadfecta - Grimalkin, EVOL, Fay, and Rainmaker

It took me a few years to pick up this full set of 4 - where each of these is a revelation - they all deliver more than you might initially think, and they do it in such a clever way. Each one of these is far greater than the sum of its parts - and all those parts are high quality THT components.

 

My only tiniest niggle here is that I feel the Grimalkin could do with a little more output volume, while all of these sound amazing, and are all super versatile.

 

We essentially have 2 fuzzes ...

My second Brelliott Modular TODP Tube OverDrive Pro has landed - this time it's the Blue Mutartis Cell Edition - with Pentode Mixer Module and Single Schottky Clipper applied

So in my previous TODP features - on the Main ’Tube’ Modules, and Clipper Boards, I detailed all the different options available and how I ended up with the Germanium Dual Clipper and Green Fetzer circuit on that version. Those were my favourite pairing. With the Blue Pentode Mixer Module + Single Schottky Clipper my very close second favourites. Those 2 pairs of boards seem to be perfect for each other - and perfectly balanced in output profile.

 

The Germanium clipping weirdly only works ...

In the wake of the quite superb recent Olbia Super-Klone - which is my favourite Drunk Beaver Overdrive to-date as well as by far and away my favourite evolved Klon sound. I thought I should do a roundup / overview of my other favourite Drunk Beaver Overdrives too.

 

This listing and visual is roughly in order of my preferences - where fortunately - the first 5 pedals listed are mostly on general release. Vitalii has made 26 Overdrives so far by my count. Actually there’s a couple of earlier ...

2026-GPX-6-Favourite-Dumbles-700.jpg

I’ve been a huge fan of the Dumble sound for several years now, and have around 20 pedals representing that genre. All my Dumbles hit slightly differently and each has a distinct usage scenario - with some excelling at the cleaner lower-gain tones - like the Clean-Fusion II, and others delivering an incredibly mid-rangey sear - like the Zenkudo.

 

My very first ’Dumble’ was the Mad Professor Simble - back near the start of 2017 - that was recently reissued as a MKII with some further Lassi ...

And here we have the GRAND FINAL- with all 36 Award Winners from the Group Stages - across all 5 categories!

 

The first two places have kind of been obvious for a while, where the 3rd / BRONZE position was actually the hardest to decide on - it was between the eventual recipient - the Tubesteader Gainlord, Boss’s XS-100 Poly Shifter, Blue FX Devices Fuzz Fields and Gamechanger’s Motor Synth - all of whom would have been worthy runners-up - while in the end I went for the one that overall ...

In many ways this is the most straightforward category with singular award nominees - GOLD, SILVER and BRONZE.

 

It’s the second smallest category after Distortions - and the one where I own the least number of pedals in proportion to the whole - just 10 out of these 26.

 

The order pretty much set itself - with the Cornerstone Nucleo being the clear winner from the start. I’m so impressed with every aspect of that pedal - it’s a perfect Trifecta of Design, Feaures and Playability - pretty ...
