DigiTech® Stomp Shop™ is your connection to all the e-pedals available for the iStomp™ stompbox. Using your iPod touch®, iPhone®, or iPad® you can turn the iStomp in to a completely different pedal with a completely new sound. In about the same time it takes to download a song you can change your iStomp from a distortion to a chorus, a flanger to an overdrive, a delay to a reverb, and more. There are more than 40 different e-pedals available in the Stomp Shop. ** Stomp Shop ** Stomp Shop allows guitar and bass players to load different e-pedals into the iStomp and try them with their own rig. You can load a new e-pedal whenever you want. Try it for up to 5 minutes before you download it to your library. The Stomp Shop app allows players to demo new sounds and new gear without having to make a trip to the store or borrow one from a friend. From the app you can listen to audio demos and learn more about the history of each e-pedal including which artists made the effects popular. ** My Pedals ** The iStomp includes 10 e-pedals. Stomp Shop remembers all the e-pedals you download. You can reload e-pedals you’ve downloaded to your library at any time. The Stomp Shop protects you from misplaced or forgotten pedals as well as from those friends who seem to permanently borrow your gear. ** Custom LED Color ** From the app you can pick a custom color for the 9-dot LED light to associate with any e-pedal loaded to the iStomp. It is a great way to differentiate your iStomp pedals when they’re on stage or in low light. ** Current Stomp Shop Pedal Selection ** -240 Plate Reverb -3Q Tone EQ -Angelic Choir -CE Chorus -DigiTech Amp Driver -DigiTech Blue Pearl Chorus (included) -DigiTech Compressor (included) -DigiTech Continuum Reverb (included) -DigiTech Death Metal (included) -DigiTech Double Cross (included) -DigiTech Jet Flanger (included) -DigiTech Phaser Beam -DigiTech Redline Overdrive (included) -DigiTech Rock It Distortion -DigiTech Total Recall Delay (1 Sec) (included) -DigiTech Vintage Tape Delay -Dirty Robot -DM Delay -DOD® FX13 Gonkulator Modulator -DOD® FX25B Envelope Filter (included) -DOD® Overdrive 250 -DOD® Grunge -Flanger Affair -Freeze Wah -Fuzzy -Glimmer Drive -Half-Pipe -Lexicon Large Hall Reverb -Magic Fingers Vibrato -Octaver (included) -Opto Tremolo -Red Compressor -Red Coral Dual Detune -Rodent Distortion -Rotator -Screamer Overdrive -Snake Charmer -Sound Off -Spring Tank -Stone Phase -Strato Boost -Swing Shift -Tone Boost -Unplugged -Vanishing Point ** iStomp Stompbox ** iStomp is a single effect stompbox for guitar and bass players. It looks and works like all other stompboxes. Kick the footswitch to turn the effect on and off. Turn the knobs to dial in the perfect sound. What makes the iStomp so incredible is the ability to turn it into any e-pedal from the DigiTech Stomp Shop. You do not have to have your iPod, iPhone, or iPad connected to the iStomp to use it. You only need to connect your device to the iStomp when you want to load a new e-pedal to it. All the effect processing is done inside the iStomp using DigiTech’s proprietary AudioDNA2 processor to ensure zero latency as well as provide studio-quality effect processing and sound quality. It uses the same signal processors found in many of the world’s best selling studio equipment and other effect pedals.

AmpStamp is a best-in-class audio processing tool for Mac, iPad & iPhone, built on true component models of vintage amplifiers and effects, with a deep library of speaker cabinets and reverbs. These are real circuit models, not captured snapshots frozen at a single setting—turn any knob and the whole amp responds the way the original hardware would. Our goal is to recreate guitar tones heard on classic albums—dial them in exactly, then push past what the hardware allowed or what was even possible at the time of recording. Create tones ranging from classic rock and blues all the way to alternative and heavy metal, with enough gain to spare. When you’ve dialed in the perfect sound, save it as a preset in the virtual Floor Controller for instant recall. And set up your favorite MIDI controller for hands-free operation whether live, in the studio, or just jamming with friends. When you need more options or want to expand your creativity, head to the Gear Shop. You can buy amplifiers, cabinets, and pedals individually or subscribe for an inexpensive all-access pass that includes all future updates and products. Get fuzzed out and sound like a classic rock hero or an early punk rocker, use flange to unleash the eighties, and everything can always use more wah. Stay tuned for new products and updates. --- VINTAGE GEAR DONE RIGHT The mobile revolution for guitar is just beginning. We are in the process of building a definitive catalogue of the most desirable tones based on our accurate models of vintage amplifiers and effects, all at your finger tips. Not only can you play along with your favorite records, you can sound exactly like them too. DRAG, DROP, ROCK We have designed simple interfaces that refocus energy on playing something cool. There’s no need to fumble with mic selection or placement, each amplifier has been tuned to sound exactly like the records that employed them. CONSTANTLY EVOLVING AND GETTING BETTER With an inexpensive subscription you gain complete access to all of our products, including future releases. It’s the best way to take full advantage of our technology as the application becomes more valuable over time. We’re continuing to track down great pieces of vintage gear so you’re going to want to be plugged in and ready. The history of rock n’ roll sound is at your fingertips. --- If you choose to subscribe either monthly or yearly, payment will be charged to your iTunes Account at confirmation of purchase.
