Product description:
Single-supply power supply, tone board with fever-grade op amp AD828, patch technology, small size design, AC and DC.
The potentiometer separate version is easy to install, is not limited by the spacing of the cabinet, and the shielded line is linked, so there is no interference problem. Both op amps feature a gold-plated round-hole socket. If the AD828 is not hot enough, it is easy to replace the better op amp chip.
