Summary

Input Stages for Hexaphonic Guitar Preamp


Description

Input Section for Hex-Preamp circuit intended only for a 6-string electric guitar. Accepts 6 inputs from a SubSix hex-pickup made by Submarine Pickups. https://submarinepickup.com . Hex-pickup cost = $389.00. This section also includes one extra channel for a normal guitar signal, plus an auxiliary channel. Each channel has its own gain control and a clean output. [The eight Input and output symbols represent 1/4" female phone-jacks.] They also each have an output going to an 8-channel mixer that is part of the overall Hex-Preamp design. The other sections are labeled "Mixer Section" and "Output Section" at this website. In particular, the Outputs shown here go to separate power-amps, while the arrows labeled MI (mixer input) go internally to the Mixer Section, and the Full-Mix Output Section processes the full-mix signal from the Mixer Section. It includes 2-band tone, a fuzz option, and output signal booster, where its output goes to a lone power-amp, such as a self-powered PA speaker. Power-supply for this section not shown. Requires a regulated dual-polarity +-15 VDC power-supply providing >= 160 mA of current. Experimental Circuitry! Fully breadboard test before committing to a soldered build. This circuit is one of three for the complete Hex-Preamp design, not counting a power-supply. All circuits are shown at this website.
