Final Booster FB-2

Full-range clean booster built entirely with discrete transistor circuitry—no ICs in the signal path. Delivers up to +20dB of boost with natural high-end harmonics that complement the guitar's existing tone rather than coloring it. The HTS (Holistic Tonal Solution) circuit provides electronic switching that eliminates the phase reversal problems common in single-transistor booster designs.

Single LEVEL knob sweeps from unity to +20dB. Does not degrade highs or lows when engaged—designed to be transparent. With sufficient amp headroom, works as a straight volume boost; into a tube amp's front end, pushes the preamp into natural breakup for drive boost applications.

Input impedance of 1M ohm with consistent output impedance regardless of on/off state. Compact 72 x 115 x 50mm at just 200g. Draws only 14mA. Discontinued.
