I haven't found that to be the case. One might be tempted to think it would, as the chambering should theoretically make the body more resonant, which eats sustain. But, the wood species, thickness, weight, etc. is still too great for the strings to have much, if any, effect on it. An electric guitar body, even chambered, simply has too much inertia. Chambering is just a weight reduction method that has little or no effect on tonal character, at least when amplified. Acoustically, you might hear a slight difference. But, while many will play acoustics electrically, few play electrics acoustically.
