The basic product from Vaudoo, the one that makes instruments rechargeable.

Rechargeable battery system (micro-USB), the B.M.S replaces the 9V battery present in your bass and active guitars.

With an autonomy greater than or equal to a 9V Alkaline battery, it delivers a constant voltage from the start to the end of the charge.

It goes perfectly with the Vaudoo preamplifier, but can also power any bass preamplifier or active guitar: 5, 9, 12 or 18 Volts.
