It is bass guitar electronics with an active three-point equalizer and active volume control.

The heart of the system is the TL062 low-noise dual operational amplifier. The functionality of the preamplifier is compatible with the design known from G&L Bass guitars.

The potentiometers are connected to the PCB with JST XHP-3 connectors. This solution allows for easier assembly and disassembly of the guitar device, allows for quick replacement of any potentiometer without soldering, and additionally allows the user to choose potentiometers of any manufacturer - each will fit after adding a connecting cable, provided that the electrical parameters are consistent. All sets are equipped with BOURNS potentiometers.
