2026-GPX-16-Favourite-Drunk-Beaver-Overdrives-700.jpg

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 ...

My close association with Thorpy started back in late September of 2018 - at the now defunct Olympia UK Guitar Show. He was the first pedal maker I reached out to, and the first I connected with.

Since then ThorpyFX Pedals have become my 3rd most populous selection after Boss and Drunk Beaver. Those 3 brands alone contribute over 200 pedals to my reference collection!

 

The fact that I’m now at 31 ThorpyFX Pedals is a major milestone - and features every mainline MKII pedal Thorpy has made. ...

This feature has been a long time coming. I have somewhere around 60 to 70 Marshall-style Pedals in my collection - while this selection mostly features Dual-Channel or Drive + Boost Pedals - which cover you both for Marshall Plexi and JCM800 flavours - actual and ballpark.

 

I landed 4 of these this year - the Crazy Tube Circuits Heatseeker, Flattley Outlaw, Fortin Kali, and Tubesteader Gainlord.

CopperSound shrink their Foxcatcher BluesBreaker take - now in sleeker V2 Compact Edition

2025-GPX-CopperSound-Foxcatcher-V2-700.jpg

CopperSound has a new version of hits FoxCatcher BluesBreaker type - now in V2 Compact Edition - minus the Boost from the V1 edition.

 

There are significant changes to the control topology - where we have lost the Nature control from the V1 - but gain a new 3-way Gain Switch, and 3-way Shape / Bass control, Those actually give you a life more overall granularity - where the Gain Switch - kind of replaces the Boost from the original.

 

I of course much prefer compact formats - but the jury’...

Warm Audio takes on the BluesBreaker and King of Tone with its expanded features Throne of Tone Dual Channel Overdrive

2025-GPX-Warm-Audio-Throne-of-Tones-700.jpg

Another smarty rolled out Warm Audio Device - albeit a tiny bit clunky for me - while you can’t dispute its exceptional feature set. The 4 knobs per channel are the KOT controls - where typically the Presence is internal to that pedal. While on my JHS 4-Star Modded Edition - the Presence Trimmers have been externalised as knobs, as have the voicing switches - allowing you to change between Boost, Overdrive and Distortion for each channel.

 

So my version of KOT has the Presence Knobs and Main...

August turned out a little bit different than expected. Not so many releases - as expected - but really busy regardless - with a number of Marquee Events and Articles throughout the month. With the king of the crop being the Extended Capacitor Primer - to which I’ve just added a further section on Capacitor Lifespan. Obviously I hit 15,000 followers on Instagram - which is a significant achievement - a really killer month all-round with some big articles - meaning I’m a little bit burned out ...

Mad Professor re-launches its Handwired Series - with the Deep Blue Delay, Royal Blue Overdrive, and Sweet Honey Overdrive

2025-GPX-Mad-Professor-Hand-Wired-700.jpg

It’s great news that Mad Professor’s high quality Handwired Series is back in circulation with 3 of its best loved pedals. I’m not sure any of these are specifically for me - as I already have the Anniversary version of the Royal Blue, and I prefer the more expansive shaping of the Deluxe format of Sweet Honey Overdrive. So I’m very happy to see these back - while the one Handwired pedal that’s high on my priority list - the Sky Blue Overdrive - has yet to be re-issued!

ThorpyFX releases lower gain Peace2Keeper Overdrive with Germanium Diodes onboard for a grittier more harmonic sound - which gets beautifully overblown when cranked!

2025-GPX-ThorpyFX-Peace-2-Keeper-700.jpg

Thorpy has always wanted to make a lower gain Germanium edged variant of his fantastic all-rounder Peacekeeper Overdrive - which is here rendered in a slightly more lower gain, lower range Peace2Keeper edition - but which benefits from the extraordinary clipping prowess of those dual Germanium OA90 Diodes. The standard version of this circuit I believe uses 1N4148 Silicon Diodes or similar - which already sound fantastic in that circuit - but where the output profile is now further elevated by ...
