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 120mA of almost totally noise and hum free 9V DC power for guitar

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 guitar

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 jeweller’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.


Input Voltage 9.0V +/- 10%
Output Voltage +/- 5%
Isolation 1000V
Isolation Resistance 500Meg ohm
Case Black ABS plastic.
Usable Temperature Range -10 to +50 Deg C
Efficiency 74%
Isolation Capacitance 4.7nF

    Virtual Battery

    It’s only just arrived, possibly due to the Post still using carrier pigeons. Thankfully the unit is well and professionally packed. Exactly what I would expect from, a great unit well thought out and a great addition to my board. I use it in conjunction with my Sun Lion from Analogman, a Great pedal powered by a great unit.

    9V Virtual Battery

    Does what it says on the tin. Allows you to have a low voltage feeding your fuzz pedal - just like a bettery running low on power. Gives that spitty fuzz sound. Very nice.

    Sounding mega with my Sun Faces :-) Only improvement I can think of is the trimmer is not very easy to access with my screwdriver a mini potentiometer to turn with the hand will be just awesome.

    Perfect! It does very well as advertised. It can be tweaked to be identical to my dying battery and even better, it stays the same! No more changing battery. The hype is real. Buy it.

    I ordered the virtual battery because a pedal on my board caused noise issues. Running it off the virtual battery has completely eliminated the hum. I could not be happier.

    Does the trick!

    I have both versions of this - the battery connector version is providing power to a Vox wah which only has a battery clip, and the DC jack version is providing power to a Fuzz Face with the voltage sagged a bit. Both are working beautifully!

    This little gizmo makes my battery powered fuzz sound the best it’s ever sounded. Epic
