UK made percolator madness; get your Albini fix!

Latent Lemon Hurts

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

As seen in The Pedal Movie in Steve Albini’s collection. As used by Pigs x7 and Placebo have a Hurts in their pedal arsenal .
The latest version of the Hurts – complete with Sputs 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 in case of oscillation.

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, unlike the alternatives these germanium diodes bring out the octave effect whilst ensuring adequate output from the vintage pedal circuit.

I wanted a Harmonic Percolator that sounded something like Steve Albini’s, but 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.


Harmonics – fuzz/distortion gain

Sputter – transistor bias

Balance – output volume

Deep switch – allows more low frequencies into the circuit and also adjusts the circuit to help prevent oscillation. Perfect for Bass and Doom!
Diode switch – Ge = germanium diodes, Si = silicon diodes, centre position = diodes bypassed.
Internal trimmers:
– Octave: adjusts the octave “sweet spot”. Set diode switch to Ge and Harmonics to max for strongest sub octave effect.

– Gain Compensation: It is recommended to leave this trimmer alone unless your pedal oscillates, in which case back it off slightly.

9V power – standard 9V DC. 2.1mm centre negative

Enclosure size: 120 x 94 x 42

Current draw – 33mA

Battery: no
