他注意到，直接用手调节收音机的旋钮来调整声音要比按住专用按钮再说“收音机——调大音量”要来得快得多。

It is much quicker to turn up the radio's volume control by hand than it is to press a special button and say "radio-raise volume," he notes.

低音音量可以用装在后面板上的控制旋钮来调整。

The bass level is adjustable with a rear panel mounted control.

哦，我们还忘了说电路控制部分，对，还是跟原厂的一样，一个音量控制旋钮，和两个音色控制旋钮，不过我们做了些细微的调整，中间档位控制的是琴颈与中拾音器的音色，后档位控制的是琴桥拾音器的音色。

Did we forget the circuitry, sure a volume control as usual, and two tones, but the middle tone works on the neck and middle pickup, with the back tone working on the bridge pickup.
