The Bassbone OD from Radial Engineering is a bass preamp with two instrument input channels, each of which is fully equipped with a level control, a passive-interactive EQ, and a low-frequency filter to help eliminate resonance. Channel-A is equipped with a PZB booster switch that increases the sensitivity and load to 10 MOhms to optimize it for use with piezo transducers as commonly used on upright bass. Channel-B is equipped with Drag Control load correction to optimize the tone and feel when using a passive instrument such as a vintage Fender bass. Toggling between channels is done using a footswitch. When using a dual pickup system, both channels may be mixed together by depressing the blend switch. Outputs include a 1/4" instrument level output to feed the artist's on-stage amplifier, plus a balanced low-Z Radial DI box output to feed the PA system. The XLR output can be assigned pre or post effects to suit your preference. A separately buffered tuner output works with the mute footswitch for quiet on-stage tuning.

If you use effects, both input channels can share the same pedals by connecting via the built-in send & receive effects loop. This is augmented with an on-board bass overdrive with control over the drive level and tone. The OD footswitch may be assigned to the loop, overdrive, or both. The Bassbone also features a built-in headphone amp with 3.5mm output.
