Enjoy great guitar effects via USB with this Virtual Amp App.

At Last, low-latency guitar effects on the Android platform. Since the Dec 2012 release of usbEffects, USB In and USB Out now supports moderately low latency which allows for a very enjoyable guitar experience.

Because USB Audio does not work with every Android device or USB device, please try out before buying this product.

The amp sim itself is very basic but includes a realistic tone-stack for nice guitar tone. This app also has a number of virtual guitar effect pedals including:

Distortion (Green Scream)
Heavy Metal (Metal of Awe)
Phasor (Phase Off)
Wah Wah
Digital Delay
Dry Layer
Basic Looper (Loop Hub)

All these effects are now configurable so you can generate a great range of sounds. The Dry layer, while aimed at Bass players, supports maintaining bass while applying effects to mid and top, or vise versa.

In addition, a basic guitar tuner has been integrated for ease and convenience as well as a Metronome and ability to play WAV files as backing tracks.

In order to use this Amp Sim, you need:

1) A , Nexus 5, Nexus 7, Galaxy S3/S4, Sony Xperia U,TX, Galaxy Note 2/Note 3, Galaxy Tab 2/3, HTC One, Galaxy Nexus or other Android device that supports OTG USB audio.
2) OTG USB cable to suit your device like (

3) Connect OTG cable to Android device and wait 1 second (USB's power light should come on).

5) Allow app to use USB.
6) If you want USB out (this is the one with low-latency) you need to go to the menu and select USB as the "Output Type", then hit the back button.

Permissions: Internet/LAN/Wifi permissions are only used for Wifi output feature.
External storage (SD card) is used for playing backing tracks and reading and writing Loops (in proprietary format only at this stage).

Not all Android devices support USB accessories by powering the USB bus. Some Android devices such as Galaxy S1, S2 do not support USB Audio. This app is not compatible with all USB devices, and in particular, "3D sound card" type USB devices are not recognized by Android and cannot be supported by this app. Finally when USB devices are powered by your phone, the battery may run down more quickly.

If you have problems with this app, or suggestions for improvements, please check our FAQ and/or email the developer.

    Sounds AWFUL !
    I realise that most of the comments are about connection and running etc.
    This app sounds like a bee farting in a jar.
    Why do we not have apps like "Amplitube", or "Ampkit".

    You won't find any other app like this on the market. It originally didnt work with my Peavey xPort but the developer actually went out and puchased one to test it & help me out. The app now works flawlessly & I couldn't be happier. The developer will really help you out & responds quickly. Thanks so much for an amazing app & hands down best customer service I've ever experienced. I can't wait to

    It was nice to be able to plug my guitar to my nexus7, and had forgotten I had it installed. The new icon drew my attention, and the new ui won me over. I'm going to put away my pod2.0 cause now I can practice anywhere. Keep up the great work !!!
