Designed as a bass command center, the Bassbone features two separate channels with independent level controls and powerful EQ to let you perform with two basses on stage and instantly select between them with a footswitch. With Bassbone in your rig, each bass is treated separately - no more compromising!

On-demand access to the combination effects loop and power booster lets you introduce effects and gives you that extra kick when needed. The Bassbone is also equipped with a built-in Radial direct box that sends 'your sound' to the mixer the way you want it. There's even a separately buffered tuner out that lets you monitor and tune on the fly.

Many bassists today use two instruments, typically with very different levels and sound. The Bassbone is designed to allow switching instruments without having to re-adjust tone and volume at the amp. This is done with two channels and an EQ with enough power and versatility to override the bass amp's tone settings!

The Bassbone can also be used with one bass with a different tonal setting for each channel, you can sound like two distinct instruments simply by switching channels. Also included is a power-booster with variable gain and a switchable outboard effect loop which can be used individually or together. For example: introduce a flanger with boost for soloing. A balanced output sends the signal to a mixer with all your sound settings (level, EQ, effect loop), eliminating the need to carry a bass amplifier to coffee house gigs. There's even a bass-friendly tuner out!
