The Bassbone V2 is a bass command center that enables one to seamlessly switch between any two bass guitars, including active, passive (magnetic), and upright (piezo). When the PZB booster is engaged, the PZB activates a special boost circuit for piezo transducers that at once increases the sensitivity and impedance to 10 meg-ohms; this results in a much wider frequency response. Two channels let you set up each instrument with its own tone and signal level. Channel-1 features two preset tones that will bring a modern vibe to older vintage amps. Channel-2 features a powerful passive-interactive EQ that lets you carve out any tone. When Input-2 is not in use, the Bassbone reverts to a 2-channel preamp that lets you create two completely different tones with one bass. A built-in effects loop lets you share pedals with both basses, and this is supplemented with a variable power booster for solos and a mute switch for quiet on-stage tuning. A built-in Radial DI box delivers the performance to the PA or recording system.
