The Radial Bassbone V2 (part R800 7071 00) is a two-channel bass preamp and DI in a floor-pedal chassis, built for bassists who switch between two instruments, such as upright and electric, or who want complete tonal control on stage and in the studio. Channel B has a three-band EQ, a high-pass filter and a PZB booster with a high-impedance input for a more natural upright or piezo tone. A shared effects loop can be assigned to either input or both, with a wet/dry blend control, and a footswitched clean boost can be reconfigured as a mute for silent tuning. The built-in Radial DI sends a balanced XLR output to the PA, with 180-degree polarity reverse and ground lift, and there are 1/4-inch outputs for the amp and tuner. Radial specifies 20 Hz to 18 kHz frequency response, 85 dB dynamic range, 0.05 percent THD, and input impedance of 220 kilo-ohms, or 10 mega-ohms for the piezo input. The 14-gauge steel chassis measures 203 x 107 x 48 mm and weighs 1.16 kg. A 15 V DC adapter is included, with Radial's three-year transferable warranty.
