FEATURE SET

1. Input Buffered – This is the primary input for your guitar and pedal

effects that do not buffer (pre-amplify) the signal.

2. Input Direct – Used when driving the Headbone from a device, like

the Radial Loopbone, that buffers (pre-ampliﬁes) the signal.

3. To Amp-1 Input – This is a ¼” hi-impedance guitar signal output that

connects from the Headbone to the input of the ﬁrst guitar ampliﬁer.

4. To Amp-2 Input – This is a ¼” hi-impedance guitar signal output

that connects from the Headbone to the input of the second guitar

ampliﬁer.

switch is factory set in a ‘lifted’ position to eliminate ground loops.

Headbone from your pedalboard using a standard contact closure foot-

switch or another Tonebone device that features a Slingshot output.
