2026-GPX-Large-Maximalist-Multi-Gain-Pedals-700.jpg

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 - ...

2026-GPX-40-Octave-Fuzz-Selection-700-.jpg

This project has been a long time in the making - I actually started off this compilation properly last autumn, and then have iterated the final selection a number of times since then - before reaching this final format. I apologise to anyone whom I’ve inadvertently left out - I still have a number of Octave Fuzzes to require - that task is never ending!

 

I own around 80 octave fuzzes so far - and this is near enough half of those - where I’ve mostly leant into compact editions - and ...

July was a tough month for me! Plenty going on for sure - and I had a particularly traumatic Sunday a couple of weeks back - when I was unable to get any sound out of my pedal-chain for the best part of that day. At the end of that I retired incredibly frustrated and kind of distraught - which zapped whatever remaining energy I had - and left me entirely shattered.

After a night’s sleep - I turned up  a little sharper on the following day - and was able to fairly quickly and systematically ...

2025-GPX-Boss-Fuzz-ology-700.jpg

So this is the 3rd and last of my Boss Gain-ology articles - and he one that’s likely to spark the most controversy. The grey enclosure ones are a given obviously, and the PW-2 Power Driver is well known for being Boss’s sort of take on the Big Muff - during the Grunge era. Notable the Power Driver only had a circulation of 6 months or so before it got pulled - so Boss’s shortest lived pedal!

 

My controversial choice here is the Lead Channel of the SD-2 Dual Overdrive - which very much ...

When Horrothia’s Tom started down this path, he was determined to make the most wide-ranging classic fuzz - one that allowed for the maximum of tone-shaping, and delivered octaves and feedback oscillation on top of a kaleidoscope of different tones and textures.

 

And what we’ve ended up with sets a new benchmark for classic fuzz, where 7 controls and 3 footswitches give you access to everything you might desire from a fuzz - there are so many clever touches to this design - that I will ...

When I first glimpsed the HARM pedal - it very much appeared to me to be the full-fat embodiment of my ’12 Degrees  of Saturation’ Methodology. Now that I’ve been road-testing it for 3 weeks, I can absolutely vouch for its potency, versatility, and prowess - its range of coverage is extraordinary!

 

This is the one compact pedal that can pretty much cover all your gain needs. That’s not to say it wholly accurately 100% replicates every gain pedal, while it most definitely gets well beyond the...

It was quite the deliberation - deciding which image should be the cover shot for this feature - on balance I think I made there right decision by picking the very first photo of the day - where Hello Sailor Effects certainly delivers that Technicolour Rainbow which looks so appealing. Moreover I snagged a one-off pedal from that stand - a few minutes before the show was officially opened - but more of that later!

So this has been on the cards for a while, in fact I needed to get an update of both boards featured here, as the first version I had was almost a year ago now. The idea was always to feature reader’s pedalboards - which had been somewhat noticeably / significantly inspired by this very site.

And I’m delighted that Long-term GPX friend and pedal fan Cyril Demaegd, board game designer / developer (founder of Ystari Games) and touring musician, has been somewhat ’Inspired by GPX’ since December of...

MIDI is essential to getting the most out of the 2 Kernom Pedals - the Moho Magmatic Fuzz, and Ridge Augmented Overdrive

2024-GPX-Kernom-Moho-MIDI-V2-700.jpg

In my recent review of the Kernom Moho Magmatic Fuzz - I already lauded it to the high rafters as the greatest Multi-Fuzz pedal ever created. It’s the perfect tool for proper fuzz fans - and in particular for those who have fully mastered the relatively tricky Zvex Fuzz Factory and similar - all those should get along with the Moho fabulously. Newbie fuzz fans may find the device a little tricky to dial in - as every knob impacts the texture and tonality of the output - so pretty much all 6 ...
