instrument level output to feed the on-stage amplifier plus a low-Z balanced Radial DI box output to feed the PA system. The XLR output can be assigned pre or post effects to suit the engineer's preference. A separately buffered tuner output works with the mute footswitch for quiet on-stage tuning.
For bassists that employ 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, tone and a wet-dry mix that lets you add slight grit or over the top distortion to the signal path. The OD footswitch may be assigned to the loop, overdrive or both. Finally, a built-in headphone amp with 3.5mm output lets you use the Bassbone on the bus for those long drives between gigs.
