Iconoclast is the state-of-the-art in guitar speaker & cabinet emulation. Instead of using static IRs (impulse responses) that cannot be adjusted in real time, Iconoclast uses proprietary filters to parameterize the speaker & cabinet, allowing you to simply and intuitively dial in the sound you’ve been looking for.
