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.

Verdict

The call

The clearest difference is in-app purchases: Wah Pedal at none against AmpStamp's 10. Wah Pedal also leads on review sentiment (67% vs 55%). AmpStamp's advantage is update cadence (every 6 weeks vs every 47 months) and rating (4.4 vs 4.2). On price, ratings volume, ads and monetization model there is nothing between them.
