Excellent preamp. Small, light, and all kinds of features. In original box with paperwork $420.00 shipped inside the US. Paypal included. The MicroBassII can be used in many different ways. For example, as an active direct box, a one or two channel preamp, instrument switcher or blender. The two channels provide sound shaping from high end solid-state types to distorted timbres using the rewarded tube emulation circuitry found in the EBS range of professional bass heads. An incorporated effects loop gives the user added flexibility for connecting to other effect pedals or for mixing in an external audio source such as CD player for rehearsal purposes. The balanced output with speaker simulator option provides unmatched flexibility in live and studio situations. The MicroBassII can also be powered in four different ways, with a DC power supply, battery, EBS Phantom Power System or 48V microphone phantom power.
