HEADBONE™ VT - SS - TS

The Headbone is a guitar ampliﬁ er switcher that allows two ampliﬁ ers to share one speaker cabinet. The Headbone lets you toggle from one ampliﬁ er to another without pops, clicks, hum or added noise. For example, the Headbone could switch between a Mesa Boogie™ Dual-Rectiﬁ er head and a Marshall™ JCM800 through the same 4-12 slant cabinet.

For the best possible tone, Headbone gives you a choice of buffered or non-buffered inputs and employs opto-couplers to ensure noise-free switching of the guitar signal. For the speaker level signals, a series of high cycle sealed relays switch the ampliﬁ ers outputs. Switching guitar and speaker signals this way ensures silent and reliable switching while maintaining the natural tone of your guitar and amps.

The Headbone is safe to use. Headbone controls the transition between amps to ensure proper loads are always maintained by connecting the standby ampliﬁ er to a load resistor. Should the power be disconnected from the Headbone, SafeMode™ will automatically revert to Amp-1. The Headbone may be switched from the rugged on-board footswitch or via the Slingshot remote.

The Headbone expands your tonal range and reduces the amount of gear you need to carry to the gig. Three models available; Headbone VT for tube amp setups; Headbone SS for solid-state amps and Headbone TS for one tube and one solid-state amp.
