Improving on the design of the original, the Tonebone Bassbone V2 Bass Preamp and DI Box from Radial Engineering is a 2-channel preamp that allows you to connect 1 or 2 basses to a single amplifier, PA, or recording destination, and also includes a boost function and switchable effects loop. Each channel offers independent level control for matching signals, along with independent EQ to suit different basses or styles. A balanced XLR output lets you connect to a PA or recording interface, while the 1/4" amplifier out allows you to hit your amp simultaneously.
A boost/mute switch allows you to either boost your signal, or mute it entirely. The effects send can be switched on and off, and even includes a blend knob that lets you adjust your wet/dry blend, and can be applied to channel 1 or channel 2, or both. A piezo booster allows you to connect a piezo pickup with no signal loss.
