Compact True Bypass Preamp Pedal Metal Build

Ultra-compact electric guitar preamp effect pedal built for sonic integrity and road-ready resilience. Dimensions: 9.3 × 3.8 × 3.2 cm (3.7 × 1.5 × 1.3 inches), weight: 155 g (5.5 oz). Full metal housing crafted from zinc-aluminium alloy provides excellent shielding and impact resistance. Input and output are standard 1/4-inch mono jacks. Powered by external DC 9 V centre-negative adapter (not supplied); polarity must be positive outside / negative inside. Four tactile knobs give full tonal command: Gain shapes drive texture and saturation depth, Volume sets final output level independently of gain staging, Bass adds foundational low-end body, and Treble delivers articulate highs without harshness. A bright LED gives unambiguous visual feedback for effect engagement or bypass state. True bypass switching uses a mechanical relay-free design for silent, pop-free toggling and uncompromised signal transparency. Ideal for players seeking a no-compromise preamp solution that fits seamlessly into minimalist rigs or densely packed boards — equally suited for Stratocaster sparkle, Telecaster twang, or Les Paul thickness.
