The pedal is constructed from heavy 14-gauge steel for durability and features Electronic Impulse Switching (EIS) for unmatched performance without the challenges posed by mechanical switches. Additionally, the Twin-City employs bright, easy-to-see LEDs for on-stage switching cues.
The Twin-City requires an external power adapter that outputs 9 to 12 volts DC with a 2.1mm barrel jack wired center pin negative, drawing a maximum of 100mA. It is important to note that using another type of power adapter may cause damage to the pedal.
The pedal also includes a ground lift switch and 180º polarity reverse switch to ensure both amplifiers play in phase while reducing noise to a minimum, even when using older vintage amps that are generally more prone to noise.
The Radial Tonebone Bones Twin-City is a powerful AB/Y switcher that delivers natural tone, punch, and clarity without inducing noise of any kind.
