i just saw danelectro 9V batteries in the last issue of musician's friend ... the ad copy that accompanies the product reads more or less like this: "ordinary 9V batteries are great for some things but they have a nasty habit of ruining guitar tone." are they kidding? a danelectro 9V will make an effects box sound better than an energizer??? is that possible??? does anyone know the answer to this ... or should i call "the psychic hotline?" i'm pretty skeptical ... although being a graphic artist by trade, i will say it's an attractively designed battery.
