1-In 4-Out Guitar-Signal Distribution Circuit

1-In 4-Out guitar-signal distribution circuit (i.e., 4-way splitter). Controls Include: Gain, Tone, Drive, and separate output 1 through 4 Level controls. With specified ICs, this is a high-fidelity circuit. For least electronic noise, avoid overdriving the Input Buffer. Frequency range above 0 dBV is from < 25 Hz to > 10 kHz, with emphasis on mids. The low -3dB reference is at 21 Hz, with 23.4 Hz at 0 dBV. The high -3 dB reference is at 21.5 kHz, with 16 kHz at 0 dBV. Circuit is recommended only for 6-string electric guitar in standard tuning. At any output, maximum gain = +21 dBV from 250 Hz to 630 Hz with all control settings at 50%, or +40 dBV from 250 Hz to 10 kHz with all controls except the tone-control at 100%. Suitable for stomp-box or rack-mount applications. The batteries can be replaced by a regulated dual-polarity +-9V DC power-supply providing >= 25 mA of current. Circuit will accept signals from active or passive guitar, effect, effects line, preamp, or processor, including those with high-level outputs. However, for cleanest operation, the Input Buffer should not be overdriven; meaning, no input voltages greater than the voltage span between the supply rails (that is, keep input signals < 18V peak-to-peak).
