Pure Tone Buffer
Compact buffer with 1MΩ input/50Ω output impedance, eliminates cable capacitance—63x60x30mm, 9V.
The Pure Tone Buffer solves the fundamental problem of cable capacitance and tone degradation in effects chains, developed in 1997 for guitarist Neil Zaza who experienced high-frequency loss when using multiple pedals and wah in signal chain. When guitar signal travels through cables and true bypass pedals, cable capacitance acts as low-pass filter progressively removing high frequencies and clarity—the Pure Tone Buffer placed first in chain presents 1MΩ input impedance to guitar pickups (preserving natural pickup resonance and harmonic content) while providing 50Ω output impedance driving long cable runs and multiple pedal inputs without tonal degradation.
Neutral frequency response maintains natural midrange clarity and treble sparkle rather than imposing coloration or compression typical of lower-quality buffers. Compact undersized enclosure (2.5x2.37x1.2") designed for mounting beneath pedalboards or tucking into tight pedalboard spaces, preserving real estate for effect pedals rather than utility devices. When placed first in chain, eliminates the "tone sucking" phenomenon where bypassed pedals and long cables dull guitar tone even when effects are disengaged.
Dimensions 63x60x30mm (2.5x2.37x1.2"), requires 9V DC power supply (1 SPOT or equivalent, not included), no battery operation. The Pure Tone Buffer targets players using multiple true bypass pedals and long cable runs where high-frequency loss and clarity degradation undermine direct-to-amp tone quality, suitable for pedalboard users seeking transparent signal conditioning that preserves pickup character rather than replacing it with buffer coloration.
