A modern, authoritatively voiced speaker, the Electric Lighting exhibits punchy, fast basses and crystal-clear highs, with a slightly throaty midrange. It covers well the ‘super cleans’ and ‘super overdrive’ tones typical of the most contemporary pop and rock music, up to the most extreme hi-gain, detuned or baritone applications.
I play in an eclectic punk band and I use two Electric Lightning with a Marshall 100 tube amp and it sounds killer most of the sound men think I am too loud but the rest of the band and the audience loves it! Thanks Jensen!
I love this speaker! I play mostly metal and hard rock in Drop C tuning, and the Jensen Electric Lightning keeps up in a closed back 1 x 12" cab. Articulation, pick attack, note separation, and depth all from the same speaker! Also, the tone of the Electric Lightning is unlike any other guitar speaker I've ever heard, which keeps me from sounding like everybody else.
