The GigRig Virtual Battery VB-DC

There's no getting away from it, some pedals just sound better on batteries. From Germanium Fuzz Faces to Wah pedals sometimes only a battery will do.

If you try to power them from a non-isolated source, such as a daisy chain, they can be noisy and in some cases can even damage your precious pedals.

How would you like all the benefits of batteries with none of the drawbacks?

TheGigRig Virtual Battery is the answer.

Available with a DC connector (VB-DC) or a battery clip (VB-BC)

The GigRig Virtual Battery is designed to deliver filtered, isolated 250mA of almost totally noise and hum-free 9V DC power for guitar
effects.

Isolation:
The Virtual Battery output is totally isolated up to 1000V. This means that there is no direct connection between the inputs and the outputs of the Virtual Battery. Isolation is achieved using a miniature toroidal transformer. This solves most hum and noise problems associated with many effects pedals and other guitars
equipment.

Virtual Fuse:
The Virtual Battery contains an output safety fuse. This fuse is designed to blow at continuous currents of over 300mA. However, being a virtual fuse, it will re-heal approximately 4 seconds after the load has been removed.

Virtual Internal Resistance:

The Virtual Battery is designed with an internal resistance of 10 Ohms. Just like old carbon-zinc batteries the voltage will drop to 6.5V DC at a load of 250mA. The Virtual Battery is designed to emulate older carbon batteries as some effects pedals (such as vintage Fuzz & Wah-Wah pedals) can actually sound better when used with these older higher internal resistance batteries.

Variable ‘Sag’ Voltage:
The Virtual Battery also features a variable ‘sag’ control (this is a small user pre-set voltage control situated just above the Virtual Battery output lead) By using a small jeweler’s flat-head screwdriver you can lower the voltage to emulate the ‘dying battery’ effect beloved of many Fuzz and other vintage pedal aficionado’s.

The key here is experimentation – use your ears to see what works for you.
