Radial ToneBone Switchbone Amplifier Switcher
The Radial ToneBone Switchbone Amplifier Switcher is a high performance ABY switcher that is designed to deliver the natural tone and feel of the instrument without introducing noise, distortion or artifact of any kind. It allows you to drive 2 guitar amplifiers at the same time and to switch between amplifiers without problems.
The Radial ToneBone Switchbone Amplifier Switcher's design begins with the same 100% discrete class-A buffering circuit as the critically acclaimed Radial JD7 Injector for exceptional audio performance. Each part is hand inserted into a double sided through-hole PCB for optimal signal transfer. To ensure the natural feel of the instrument is maintained, Drag control load correction lets you re-introduce the natural relationship between the guitar pickup and the amp that is invariably lost when the guitar signal is buffered. This also allows longer cable runs of upwards to 15 meters (50') without noise.
There are three footswitches on the top panel: The first selects between A or B amps while the second is used to combine amps. To get rid of the pops common to passive switchers, the Radial ToneBone Switchbone employs photocells that ramp-up the signal for smooth noise-free switching - even when used with high gain amps. To eliminate hum and buzz caused by ground loops, the Radial ToneBone Switchbone's second output is equipped with a transformer for 100% isolation. To ensure the two amps play in absolute phase, you simply toggle the easy access 180º polarity reverse switch.
The third footswitch lets you engage the built-in power booster. This is equipped with a variable level control and is augmented with a 3-position mid-boost switch for extra cut when soloing. The boost function can be bypassed and converted to a mute switch for quiet on-stage tuning. A separate tuner out is always on for quick tune-ups and buffered to keep your signal path clean. Smart 'flashing' LEDs let you know which amp was last selected keeping you in total control at all times.
The Radial ToneBone Switchbone is the most natural sounding ABY amp switcher made today.

Radial ToneBone Switchbone Amplifier Switcher Applications
- Standard ABY setup - The Radial ToneBone Switchbone is a high performance ABY designed to deliver the natural tone of your instrument to your amps without introducing noise or artifact.
- Adding a tuner to your setup - Drive two amps plus your tuner at the same time. Photocell switching, transformer isolation and buffered outputs eliminate popping, ground loops and noise of all types.
- Used as a channel selector - For older amps, the Radial ToneBone Switchbone can be used to drive the two amp channels so that you can toggle between them. The 180º polarity reverse ensures both channels play in phase.

Great ABY! No signal degradation when driving two amps at once and no thumping when using as an A/B switch. The mid boost and drag controls really help to dial in your tone. On top of all this, I saved $50 by purchasing a demo unit that looks like it's brand new. Thank You Front End Audio!
Purchased a Radial ABY that had an open box but was otherwise in perfect shape. Great price. Quick delivery. Pleasure doing business with you.
