StompBox turns your iPad into a fully fledged digital effects unit, complete with chromatic guitar tuner, metronome and loop recording tools. StompBox allows you to build a rack of effects in any order and then save your settings as patches that can be recalled at the press of a button.

With StompBox you get the best of both worlds, a rack of professional sounding stereo effects (with far more control than simple foot pedals) and a foot controller to access a tuner and all your patches.

Simply listen through a pair of headphones, or attach to an external amplifier or hifi to truly experience the program in all its glory. StompBox uses stereo routing between effects, which results in a very professional sounding experience.

In order to use StompBox you need a way of connecting your guitar. The simplest way to accomplish this is to use an adapter such as the Apogee Jam or iRig (sold separately), but if you have a camera kit you may be able to use an inexpensive USB sound card. For further information on compatible interfaces please see our Audio Interface Video and the compatibility list in our forum.

StompBox comprises 17 unique effect modules such as delay, reverb, flanger, phaser, chorus, pitch shifter, tremolo etc. We have also included a noise gate, compressor, parametric and graphic equalizers so that you can create many unique and interesting tones. There are 7 types of distortion effect available (from overdrive, to fuzz to full out classic distortion) as well as custom amplifier EQs, so plenty of scope for all types of music.

Once you have built up a library of patches, you can use the virtual foot controller to quickly and easily move between patches. The Virtual Foot controller gives instant access to all patch parameters and amp settings, with the ability to enable and disable individual effects at the touch of a button. If you want to modify an effect parameter, simply scroll the effect rack into view and make your changes. The foot controller has a virtual whammy bar which can be controlled using the touch screen or optionally using the accelerometer. A tap tempo button is also available to synchronize all time based effects.

StompBox includes a Metronome which you can use for practising or alternatively you can load your favorite MP3s into the Media Player and play along. The Media Player even has the ability to slow down the music without effecting pitch so you can play along at your own pace. You can even loop a particular part of a song so it plays over and over again.

StompBox also features a 4 track loop recorder. This allows you to record your own backing track which can also be looped, just like the Media Player. You can record up to 4 non-destructive overdubs and even save a mixdown for posterity.

As most guitarists will know the choice of Guitar Amp is very much a personal choice. If you are playing acoustic or semi-acoustic then you will more than likely opt for an acoustic amp as the sound is less harsh (as they are not EQ'd to death). Many guitar applications use a form of Amp Modeling which in most cases is just fancy form of EQ. This is great for electric guitars, but not so good for acoustic. StompBox allows various amp EQs both via the PreAmp and additional effects, but the important thing for acoustic guitar users is that these EQs can be completely bypassed. This is where StompBox really shines, giving a faithful reproduction of acoustic instruments. This also means StompBox can be used on keyboards too.

The MIDI Support allows you to use remote pedal board to change patches, control Volume and Wah pedals as well as tap tempo etc. This is completely configurable by assigning MIDI CC's to StompBox functions. The Learn feature makes configuring the softer very simple.
