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. --- VINTAGE GEAR DONE RIGHT The mobile revolution for guitar is just beginning and we are in the process of building a definitive catalogue of the most desirable tones based on 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 design 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. --- FEATURES - Universal App available on Mac, iPad & iPhone - Run as Standalone or Audio Unit (AUv3) App Extension - High-resolution audio—support for 44.1/48/96/192kHz sampling rates - Stereo output with Ambience effects - MIDI support for hands-free control - Sidechain input for select effects - Cabinet Drive for select effects - Free TU101 Strobe Tuner now available, ±0.1 cent typical accuracy - NEW Transformer Saturation for select amps If you choose to subscribe either monthly or yearly, payment will be charged to your Apple Account at confirmation of purchase.
