Re-coded from the ground up. The Emissary is a no-compromise custom amp built for the kill. Featuring a versatile clean channel that ranges from pristine cleans to slightly overdriven tones. A brutal lead channel designed for serious bone-crushing distortions. This module offers a very wide tonal palette for not only the modern metal musician, but a wider variety of genres. Every single component on the signal path of the circuit of the physical Emissary tube amplifier has been taken into account and modelled in the best possible way to match the original sound, keeping an eye on CPU performance and real-time playability at the same time. We use state of the art analog modelling technology, deriving systems of non-linear differential equations directly from schematics and solving them in real time through carefully optimized C++ code. Also included are 6 free Impulse Responses.
The NadIR dual Impulse Response (IR) convolver, designed to be used as a cabinet simulator for guitar and bass (pre)amplifiers (VST/AU or even hardware), with ZERO latency. Providing advanced built-in filters and delay controls to let user's shape their tone with ease.
