Analog Music Co. finally releases its much anticipated unique, visceral hybrid-transistor Notorious Rabbit Analog Octave Fuzz

So what we have here is a very unique Analog Octave Fuzz circuit construction - with a raw and ragged, extreme, visceral output - bordering on ’nasty’ at times even - in the best possible sense of that word! This is a crushing high gain octave fuzz to shake your world!

Controls - Attack (Gain), Level, Voicing / Input Filters : More Mids / More Lows.

This is a unique signature pedal and statement piece from Analog Music Co.’s Konstantin - it’s a kind of harmonic fuzz - generated through a complex interaction of expertly selected components (a mix of SMT and THT parts) - arranged in an evolved configuration. Konstantin has honed and evolved this fuzz via 3 different iterations - with the MKI edition being completed in 2023, MKI.5 in 2024, and the MKII this very year (2025) - being launched today - on the 16th of May!

Konstantin defines this as am extreme nonlinear gain circuit whose signal processing starts with the ’Voice’ input filters (More Mids / More Lows), it then passes through a pair of NOS / Vintage 1 x Germanium + 1 x Silicon Transistors in Darlington configuration, then through a 1N5817 ’Clamping’ Diode which also adds asymmetrical clipping into proceedings. The signal then gets boosted by an OpAmp - for one of the raspiest, gnarly Octave Fuzz outputs you can get - and which is extraordinarily textured to go with its extreme high gain output profile.

Representing Analog Music Co’s core philosophy for making entirely unique and differentiated effects pedals - well removed from anything any other builders might do - this is a future vision of ultimate flexibility in small batch manufacture - delivering a wide variety of different editions for its effects - so that there are rarely two exactly the same.

To that end - the Notorious Rabbit comes in 13 different colourways - where I’ve selected my 9 favourite ones below. There are versions of the MKI, MKI.5 and MKII available - with the MKI.5 and MKII the same circuit in very slightly different enclosures - those latter versions are a tiny bit more ’unleashed’ than the MKI edition which has a slightly different arrangement. These are all priced at a very reasonable $230 drirect from Analog Music Co, and via their Reverb.com Store .

I was supposed to have one of these for launch - which didn’t happen as Konstantin was still refining the circuit - he did manage to mail one out to a significant number of demoers though - as at the base of this article. I will be getting a hammered gold version as pictured - although I’m not clear on exactly when that will happen.

It’s a shame I didn’t get hands on with one of these in time for launch - as I would have had much more to say - including a better basis of comparison to the 40 or so Octave Fuzzes I already have. I can say that all of the demos sound excellent - and in particularly Ambient Trash Matt’s one - which heads up that selection. Obviously different playing styles deliver slightly different tones - while Matt’s demo delivers maximum flavour - even though he’s playing a MKI edition - which is not quite as ferocious as the MKI.5 and MKII!
