Powered by dual power sources, the tone board adopts enthusiast-grade op amp NE5532, made by patch technology, small size design, AC and DC dual use. 

The separated version of the potentiometer is easy to install and is not limited by the distance between the casings. The shielded wire is connected and will not cause interference problems. The two op amps are equipped with gold-plated round hole sockets. If you feel that the op amp is not enough to have a fever, you can easily replace a better op amp chip by yourself.
