​You may recall Headrush from such awesome delay pedals as, well, the ‘Alesis’ Headrush Delay & Looper pedal. This was iconic. The company that purchased Alesis also owns Digitech and the technology behind Digidesigns Eleven Rack processor. One of the pioneers of modern digital amp modelling. They had full access to the ‘magic’ behind this rack processor and gave it to a ‘genius digital type guy’ who tweaked the programming, modernised the modelling algorithms and upgrade the bit rate massively. The new Headrush (now the Brand itself is called Headrush) contains a quad core processor for extremely smooth and seamless processing.
