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.
