Features & Specifications
The Radial Headbone combines simplicity with functionality. Hook-up was designed to be intuitive for all users, be they neophyte or experienced technician. Although most will be able to connect and play through the unit immediately, we recommend a thorough reading of the user guide first for best results and safety.

In use, the Cabbone is a model of logical design and offers the professional guitarist the ultimate in creative options on stage through smooth and noise free amplifier switching.

An on-board footswitch toggles between amp heads and large LED indicators monitors the current signal path. Tonebone's versatile Slingshot™ system allows remote controlled switching between heads from any stage position (eg.: a pedalboard) using just regular ¼" to ¼" guitar cables.

  Maximum Power Ratings
To switch the speakers inside the Headbone, a relay is used that is rated for 100 Watts (MUSICAL PROGRAM). This 'general' specifications does offer some leeway as detailed below. Please consult your local Tonebone dealer to ensure your system is configured to meet the following specifications:
100 Watt into 4 Ohms
 = 5.00 Amp RMS
100 Watt into 8 Ohms
 = 3.54 Amp RMS
100 Watt into 16 Ohms
 = 2.50 Amp RMS
150 Watt into 4 Ohms
 = 6.12 Amp RMS (safe)
150 Watt into 8 Ohms
 = 4.33 Amp RMS
150 Watt into 16 Ohms
 = 3.06 Amp RMS
200 Watt into 4 Ohms
 = 7.08 Amp RMS (not reccomended)
200 Watt into 8 Ohms
 = 5.00 Amp RMS
200 Watt into 16 Ohms
 = 3.54 Amp RMS
Safety Note: Although the headbone relay is rated to withstand a 10 Ampere load, due to peak power surges and the total power caused by heavily distorted sound, we recommend a 40% minimum safety margin for a maximum 6 Amps of current be applied.
