As part of the growing line of Tonebone foot pedals, Radial introduces the Headbone VT, a guitar amplifier head switcher that allows the player to transition from, for example, a Mesa Boogie Dual-Rectifier to a Marshall JCM800 while using the same cabinet. The Headbone employs a series of photocells to assure noise-free guitar-to-head switching and a series of high cycle relays that switch between the 2 heads and the speaker. A digital programmable interrupt controller receives commands from the onboard footswitch or the Slingshot remote switching system and controls the transition between equipment to ensure proper amplifier loads are always maintained.
