Lil’HarpZone was initially motivated by a custom order…
It is now available to everyone !
Lil’HarpZone is a low sized transposition to harp of the famous Metal Zone distortion pedal.
It takes back most of its saturating circuit and features a specially designed One Knob Tone control.
Lil’HarpZone, and its simple controls.
General features
• Universal input, dedicated to all kinds of mikes.
• Saturating circuit ans its pre-filter close to the MetalZone®.
• Diode + LED circuitry improving the dynamics of saturation.
• 2 voicings “Sharp” and “Warm”…
• One knob tone knob, with simultaneous action
on the treble and the mids…
• Low impedance output.

Interior and detail of the card, with the vintage integrated circuits providing amplification: JRC4558D and MC741N.
Technical details
Overdrive circuit
• The overdrive circuit is made up of an operational amplifier, classic in the world of overdrives / distortions of the 70s to 90s: the JRC4558D.
• It attacks a composite network consisting of a 1N914 silicon diode and an red LED.
this combination improves the level and dynamics of the distorted signal, as well as a more textured tone, without being harsh.
Standard gain settings according to microphone type
The settings below apply to a microphone without a potentiometer, or with a potentiometer set at its maximum.
The benchmarks are given for a moderate saturated rendering.
Bullet mike, piezo or ceramic technology
(antique: JT30, Green Bullet… neo-old: Superlux D112/C)
• High nominal output level, high impedance.
• Recommended gain setting: between minimum and 9:00, or more for a violent saturation.
Dynamic old or neo-vintage mike
(Shure Control Magnetic, Shure 515, 588 switched on HiZ,… Bottle O Blues, Silverfish…)
• Nominal output level close to a guitar, Mid or high impedance.
• Recommended gain setting: between 9.00 andt 10.00, or more for a distortion with balls.
Dynamic modern mike
(Shure 55SH “the skull”, 565D, SM57, SM58, Audix Fireball V…)
• Nominal output level: 10 to 30mV, low impedance.
• Recommended gain setting: around 12:00 — or higher for more pronounced overdrive.
Tone control
This montage designed by GuitarPoppa is intended to be easy to use, but rich in effects.
• It is almost neutral when the button is set at 12:00.
• On both sides, it acts simultaneously and reversely on the mids and the treble :
To the left : attenuated treble, accentuated mids then low mids.
• To warm up a harp that is a bit too strident…
• To find “sweet spots” that sounds like old vintage amps…
• To increase the growl of a deep overdrive or a fuzz…
To the right : accentuated treble, medium hollow more or less accentuated.
• To find a sweet spot between warmth and brilliance, in clear or saturated sound…
• To lighten the lower midrange with some somewhat throaty harps…
• To deliberately freeze the sound like in italian westerns.
These filterings are very sensitive to the grain of input signal :
The best instrument/fuzz grain/tone combinations often depend on light differencies of Gain and Tone adjustment.
Be curious !
Power supply
Lil’HarpZone is powered a 9V battery or an external 7 to 12V power supply.
• Typical current with 9V : 8mA.
• Internal electronic filtering eliminates common power supply noise.
• The sound is typical at 9V, it is a little more dynamic at 12V.
Conversely, it compresses and can become filthy when below 9V.
