The infamous Harmonic Percolator circuit tuned for maximum tone. Capable of filthy sub octave and wilful feedback, through to just a hint of grit, or an amp slamming transistor booster. Definitely more than just a fuzz.

As in the original HP-1 the Hurts uses both germanium and silicon transistors carefully selected and graded for both sound and gain. Inside it has a couple of trimmers, one to tune in the octave "sweet spot" and one for gain compensation. 

It uses 1N695 germanium diodes as in the original HP-1 and has a switch to change to silicon diodes which are slightly louder (my favourite on bass). In the mid position this switch bypasses the diodes making it a loud transistor booster that really pushes the front end of an amp. I have bought up the last of the best quality 1n695 diodes I can find, these germanium diodes bring out the octave effect whilst ensuring adequate output from the vintage pedal circuit.

Each pedal is handbuilt to order in Luton, England. They are built to last and with a view to servicing in the future.

When I made my first Harmonic Pecolator I never guessed I would be selling them around the world! The idea was to build one for me and another to sell to pay for the parts, Ash from Magic Mountain has the other original with its glow-in-the-dark blue paint!

I had wanted a Harmonic Percolator that sounded something like Steve Albini’s, but I couldn't find the sub-octave throaty HP-1 sound I was looking for - especially after I luckily got to record an old 70s original Ed Giese Interfax HP-1 which sounded amazing!

Anyway, back in 2012, after more breadboard experimentation and research than is probably healthy, I came up with the Hurts pedal. Although I have now changed the name from 1000 Hurts to just Hurts, it is still exactly the same circuit.  


Available mods:

Bass Density Switch – this has an added switch to let more low frequencies into the circuit.


Hurtsenboost - this mod adds a bypassable MOSFET booster option. It sounds glorious and LOUD!


Temperature compensation switch – I have experimented on a few pedals with temperature compensation (if you have one of these they are very rare!). Part of the nature of germanium transistors is that their characteristics can vary with temperature, if they get extremely hot or cold the tone/drive may change. The temperature switch helps to compensate for this, if you are likely to play gigs in saunas or in full desert sun this is for you!

On this Ex Wives track the guitar setup  is EGC guitar - Hurts - Bassman amp. They also have the first Hurtsenboost pedal - the Hurtsenboostenstein!

Hurts demo with P90 pickups:

“I dont know how to thank you? You’re attention to detail... you nailed it. You have the best harmonic percolator on the market. Truest to Interfax as far as I can tell. Plus your pedal just out right kicks ass with all the options you offer in Ge and Si switches and so on. This pedal knocks all other HPs in the dirt. Including the (name removed - Ed.) cause I got one of those. Kudos, man. Playing it through my Orange amp... makes me the happiest kid in the world. Where may I leave a positive review, sir.”


My original prototype pedal demo which became the Hurts:

Bass demo, note that the density control is now a switch which not only allows more low frequencies into the circuit, but also alters the internal gain to avoid oscillation. With the Density switch off the pedal is a regular Hurts:
