AppAdvice has once again teamed up with IK Multimedia in order to offer you a chance to win one of five (5) promo codes for AmpliTube for iPad ($19.99).

IK Multimedia is liquidating a handful of final promo codes before AmpliTube 2 for iPad makes its way to the App Store’s virtual shelves very soon. That means those not lucky enough to be the winners of the previous giveaway have another shot to grab a free copy of this sweet app. As a reminder, v2.0 is a free update for all current AmpliTube for iPad owners, so don’t be shy about getting equipped sooner rather than later.

AmpliTube for iPad gives you amazing guitar amps and FX, and when combined with the $39.99 iRig plug interface adapter, becomes the ultimate guitar and bass MultiFX system right in your backpack.

Your new mobile rig gives you up to four simultaneous stomp box effects — the iPad is capable of doing one more than the iPhone and iPod touch, an amplifier, plus speaker cabinet and a microphone. AmpliTube for iPad includes stomps for delay, fuzz, overdrive, wah, envelope filter, chorus, flanger, phazer, octave, noise filter + distortion, powered by a clean, crunch, lead, metal, or bass amp. Additionally, choose amongst five cabinet and either a dynamic or condenser microphone.

AmpliTube for iPad has a built-in chromatic digital tuner and a metronome to offer an increased level of accuracy, especially in noisy environments, due to the fact that your instrument is plugged directly into your iDevice. Import and play along with your own songs or backing tracks with real time effects plus the ability to create, save and recall up to thirty-six presets on the fly.

You can even try AmpliTube for iPad‘s features without a guitar by using the built-in demo section. Choose one of the eight guitar audio riffs, click play, and go try some different amps and sound-FX.
