AKAI Headrush II

AKAI Head Rush is a delay, tape echo, and a looping recorder. User-selectable delay options allow for maximum control of output signal. Real-time feedback and gain adjustment as well as echo rate enable sounds to be shaped with precision. E2 HEAD RUSH also simulates a four-head analog-tape machine with control of decay and spacing between virtual-tape heads to create complex multiple delays and repeats. The signal from each virtual head appears on an individual output for multiple returns when used with an external mixing console or multiple amps. Looping Recorder mode enables you to record and overdub layer after layer of sound in real-time, making E2 HEAD RUSH an unbelievable live performance tool. Depending upon which mode is selected, the left footswitch controls the on/off and play/stop functions while the right footswitch sets the tap delay time or recording and overdub options.

Famously used by Jonny Greenwood (Radiohead) and KT Tunstall among many others.
