Features

DI MODEL function with 6 tone types (tube x3, solid state x3)

The dynamic timbre changes (hysteresis characteristics) produced by the transformer that characterize the DI sound are formulated into a mathematical formula and modeled precisely. Reproduces subtle differences in overtones, compression, and other characteristics obtained by passing each DI. Just like professionals, six different DI models can be used according to the acoustic characteristics of the live venue and music genre.

Multi-layer IR" dynamically blends three IRs according to the strength of the picking.

Conventional general IR uses a single impulse response to capture the characteristics of the speaker cabinet. The new "Multi-layer IR" technology uses three impulse responses captured at different volumes (LOUD / MEDIUM / SOFT) and dynamically blends the three IRs according to the volume of the bass and the strength of the picking, creating a different level of fidelity and organic sound, responding just like a real cabinet. The three IRs are dynamically blended according to the volume and picking intensity of the bass.

The 3IRs are optimized for bass characteristics, providing a sharp attack and a clear low end.
