Latent Lemon Audio - Hurts

Harmonic fuzz, Percolator, distortion, OD, boost

The Hurts - now with Sputter control! This lets you alter the transistor bias which allows you to go from classic dad-rock tones to Mr. Albini and beyond! This is the Hurts with the Deep (bass mod) switch mod. This switch allows more low frequencies into the circuit making it ideal for Bass and Doom! The Deep switch is also sounds great on guitar, please check out my YouTube channel for a demo.

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 in case of oscillation.

It uses best quality 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 volume 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 built 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.

Controls:
Harmonics: fuzz/distortion/overdrive gain control
Sputter - transistor bias
Balance: output volume
Diode switch: Ge = germanium diodes, Si = silicon diodes, center position = diodes bypassed.
Deep - this allows more low frequencies through the circuit, great for both bass and guitar.

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.

Top quality components: Alpha footswitch, Lumberg power socket, Neutrik jack sockets, Hammond enclosure etc. Latent Lemon designed circuit boards. Hand built to last in Luton, England.

9V power - standard 9V DC Boss style power supply.
