The Lightning's interactive tone controls influence each other in a very dynamic way and pull each other's range and reach up and down. Actual tonal possibilities are very extensive and it produces loud output volumes not normally associated with a 15 watt rating.
The Pro-grade single channel preamp with its interactive tone controls is coupled to a serious dual-EL84 power section with a tube rectifier. All models have active EQ to attain an excellent array of complex tones. User controls include Volume, Interactive Bass & Treble, and Master Volume.
