Lusithand F1 Dual Filter Pedal
The Lusithand F1 is a powerful dual-filter pedal built for players who want deep control over frequency movement, resonance, and tone shaping. Using the same filter topology found in Lusithand’s NFP filter preamps, the F1 offers two separate filters that can be blended together for everything from subtle utility EQ work to expressive, synth-like filter effects.
The left filter sweeps from 50Hz to 6kHz and can be switched between Low-Pass and High-Pass modes. The right filter sweeps from 120Hz to 4kHz and offers selectable Low-Pass or Band-Pass operation. Each filter has its own dedicated RES control, allowing you to keep the response smooth and fairly flat or push the resonance for more pronounced, vocal-like peaks.
A central PAN control blends the two filter paths together, opening up a wide range of creative textures and practical tone-shaping options. Use it to tighten low end, tame harsh frequencies, create sweeping filter effects, add movement to bass lines, or carve out space in a mix. Whether you are using it with bass, guitar, or studio gear, the F1 works equally well as a creative effect or a precise utility tool.
Designed for high-headroom performance, the F1 features an internal voltage doubler that allows up to 36V internal operation when powered from an 18V supply. This gives the pedal excellent dynamic range and helps prevent unwanted clipping from hotter signals, making it a strong choice for modern pedalboards, active instruments, and studio setups.
