Treble Adjustment Instructions:

The treble adjustment potentiometer has two functions:

1> When the potentiometer is adjusted to the left (within the range of 3/1 clockwise), the BBE is straight-through (that is, the bbe function is turned off);

2> Adjusting the range outside 3/1 of the potentiometer clockwise is to enable the bbe function, and the potentiometer is used for treble adjustment at this time. In this way, there is no need to add a bbe switch, and the bbe can be controlled on and off by adjusting the treble potentiometer, which is more convenient to use and kills two birds with one stone.
