In the past, digital multi effects in general were criticised by public that they produce a dull, lifeless sound. Hotones aspiration is to eliminate this stereotype and devote their best efforts to make it sound authentic and genuinely feel like what you would perceive from a real amplifier. Based on decades of research and empirical practice in the field of digital modelling algorithm, Hotone team is able to unveil and unbox the ultimate weapon, the CDCM HD + F.I.R.E modelling technology, a combination and recreation to the mainstream white box and black box modelling technologies. This technology models every component of the original device, building a model that tracks the dynamic variations of the instrument's input signal, which maximises the capability for the reproduction of the exact sound characteristics of the modelled object, delivering a more dynamic, deep, in-the-moment tonal feel. International professional musicians who have embraced this technology are enamoured by how live play becomes so unbelievably realistic.
