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 http://githarastudios.com/downloads/usbEffectsLite.apk 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)
Flanger
Phasor (Phase Off)
Chorus
Harmonizer
Wah Wah
Tremolo
Digital Delay
Dry Layer
Reverb
Looper Pedal (Loop Hub)
Vibrato

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.

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.
