Bassbone V2 Preamp

Radial Engineering Ltd.

OVERVIEW

The Bassbone V2 is a powerful two channel instrument preamp that is 

able to handle all types of bass instruments and pickups depending on 

how it is configured. Some examples include:

1. Using with one bass

: When one bass is connected, the Bassbone

automatically converts to a two channel preamp. You can toggle to

channel-B and use the powerful EQ to make a vintage passive bass 

sound like a modern active.

2. Using with two basses

:  Connecting  a  second  instrument  to  the 

INPUT-B jack turns the Bassbone into a two 

instrument

 preamp. You 

can toggle between instruments by stomping on the footswitch.

3. Switching between upright bass and electric bass

: The Bassbone 

is equipped with a special PZB booster circuit that allows a passive piezo 

transducer to connect directly to INPUT-B. This lets you quickly transition 

from an electric bass to a piezo equipped upright bass.

4. Mixing two pickups

: Players that use acoustic/electric basses with 

two pickup systems can employ the Bassbone's unique BLEND function. 

This turns both channels on and lets you mix the sound of both pickups.
