{"product_id":"lehle-mono-volume-90-311982","title":"Mono Volume 90","description":"\u003ch3\u003eA \"high-end\" approach to the volume pedal: Hall sensor and VCA instead of a potentiometer\u003c\/h3\u003e\u003cp\u003eMost classic volume pedals rely on a mechanical potentiometer: over time, wear and friction often generate noise and less consistent response. The Lehle Mono Volume 90 takes a different approach with a high-precision magnetic sensor exploiting the Hall effect (discovered by Edwin Hall). Here, the rocker plate moves only a magnet; the sensor measures its position, then controls a VCA (voltage-controlled amplifier). The result: a very fine control feel, exemplary repeatability, and a lifespan designed for both stage and studio use.\u003c\/p\u003e\u003cp\u003eThe Blackmer-type VCA (made in the USA) replaces the potentiometer: no more \"pot noise,\" no drift, and above all, signal fidelity that remains stable throughout the sweep. Internally, the voltage is processed then doubled to operate at 18 V, which improves level handling and contributes to a dynamic range rated at 110 dB.\u003c\/p\u003e\u003ch3\u003eWho it's for and what it's for: swells, level management, pro pedalboards, and pedal steel\u003c\/h3\u003e\u003cp\u003eThe Lehle Mono Volume 90 is aimed at musicians who want a \u003cstrong\u003etruly transparent volume pedal\u003c\/strong\u003e : guitarists (clean, crunch, rock, fusion), bassists, and amplified acoustic instrumentalists. It excels for \u003cstrong\u003eswells\u003c\/strong\u003e in the \"violin\" style, smoothing rhythm parts without touching the guitar's pot, or for precise level control in live situations with great gradation.\u003c\/p\u003e\u003cp\u003eIn the studio, it becomes a clean gain staging tool: you can control the level going to an amp, channel, interface, or effects chain without the \"veil\" effect in the treble often found on some traditional volume pedals. The side-mounted connectors also facilitate integration for \u003cstrong\u003epedal steel\u003c\/strong\u003e players by keeping the front\/back area free depending on setup.\u003c\/p\u003e\u003ch3\u003eControls, outputs, and mechanical design: precision underfoot\u003c\/h3\u003e\u003cp\u003eTwo controls allow you to adapt the pedal to your use. The \u003cstrong\u003eMIN\u003c\/strong\u003e knob sets the minimum level at heel position: from \u003cstrong\u003emute (0%)\u003c\/strong\u003e up to about \u003cstrong\u003e-10 dB\u003c\/strong\u003e (approximately 90% of the original signal). The \u003cstrong\u003eGAIN\u003c\/strong\u003e knob defines the maximum level and allows a \u003cstrong\u003eboost up to +12 dB\u003c\/strong\u003e : useful for raising a solo, compensating for a quieter guitar, or slightly pushing an amp's input.\u003c\/p\u003e\u003cp\u003eThe pedal remains particularly quiet and smooth thanks to \u003cstrong\u003elow-friction smooth detents\u003c\/strong\u003e made from high-performance polymer, which limit mechanical transmissions. An \u003cstrong\u003eadjustment screw\u003c\/strong\u003e allows precise tuning of the rocker resistance, from a very free sweep to a firmer vintage-style feel.\u003c\/p\u003e\u003cp\u003eFinally, the \u003cstrong\u003ebuffered DIR output\u003c\/strong\u003e is a real plus: it sends the input signal without volume variation, to feed a tuner (while muting the volume output at heel), a DAW, or a second amp without degrading the sound.\u003c\/p\u003e\u003ch3\u003eSound quality\u003c\/h3\u003e\u003cp\u003eThis is an \"audiophile\" volume pedal: the Mono Volume 90 aims for \u003cstrong\u003eneutrality\u003c\/strong\u003e and \u003cstrong\u003efidelity\u003c\/strong\u003e. The signal retains its harmonics and attack, with a consistent response throughout the sweep. Input and output impedances remain identical, avoiding the common treble attenuation effect. Add to that a wide bandwidth and very low noise floor: the pedal disappears into the signal chain while providing a very precise foot control feel.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical
