Bumper Instrument Selector Pedal

The Tonebone Bumper is a unity gain instrument selector that lets you connect up to four instruments and progressively advance through each input using a sequential footswitch. The sequence is determined by the input conections, whereby if only two instruments are plugged in, the footswitch will only toggle between the ones that are connected.

Each input features Radial's award-winning Class-A buffer for absolute fidelity while enabling longer cable runs without signal degradation. This is augmented with Drag control load correction that lets you adjust the load on each instrument for optimal signal transfer, natural tone and feel. Drag works equally well on single coil or humbucking pickups – on both electric guitar and bass. A selector switch for each input changes the Drag control to a Trim to balance louder sources such as an active bass or acoustic guitar with passive counterparts. This lets you quickly switch instruments without having to readjust levels on the stage amp. In addition to the 1/4" stage amp output, the Bumper is equipped with a separately buffered tuner output. This is always on to allow on-the-fly tuning while eliminating any clocking noise or loading caused by the tuner.

Compact and made from 14-gauge steel, the Bumper is well equipped to protect against the harsh environment of professional touring while ensuring the instrument signal will be shielded against stray magnetic fields. Powered by a standard 9V supply, it can easily be integrated into a pedalboard using an off-the-shelf Boss-style supply or multi-output power brick.

The Tonebone Bumper is the perfect interface for multi-instrumentalists, studio session players or artists that employ several guitars on stage.
