Radial ToneBone Bassbone OD | Two Channel Bass Preamplifier

The Radial ToneBone Bassbone OD is a top-tier bass preamplifier that offers unparalleled versatility and performance for professional bassists. Designed to accommodate both electric and upright basses, this dual-channel preamp features highly customizable inputs, an integrated overdrive, and a suite of outputs that make it invaluable both on stage and in the studio. Whether you are toggling between instruments or fine-tuning your tone, the Bassbone OD equips you with the controls you need to achieve sonic perfection. Its robust construction and intuitive layout make it perfect for demanding touring schedules and rigorous studio sessions.

Channel-A is specifically optimized for piezo transducers commonly used with upright basses, featuring a PZB booster switch that increases sensitivity and load to 10 meg ohms. Channel-B, on the other hand, offers Drag Control load correction to fine-tune the tone of passive electric instruments, ensuring a warm, natural sound. The footswitch-operated channel toggling and blend switch make it easy to switch between or combine the two channels in real-time. Unique outputs, including an instrument level output and a balanced low-Z DI, allow seamless integration with a PA system and on-stage amplifier, while a built-in tuner output and mute footswitch facilitate quiet tuning.

The built-in overdrive and effects loop add another layer of versatility, offering a wet-dry mix and control over drive level and tone, allowing you to dial in anything from subtle grit to full-on distortion. The headphone amp with a 3.5mm output ensures you can practice privately, even on tour buses between gigs. Coupled with a 15VDC power supply, the Bassbone OD is the world's most powerful bass preamp in a pedal.
