ELECTRO-HARMONIX ELECTRO-HARMONIX SWITCHBLADE + Almost unused, so it's in beautiful condition. I've confirmed basic operation at the time of listing. Price negotiations are not accepted. The ELECTRO-HARMONIX / Switchblade + is a simple 2-mode passive AB BOX. In addition to the typical A or B, it also offers A+B output and a tuner out, making it useful in various situations.
