Careful emulation of what is probably the best known and legendary combined tape echo / spring reverb device ever, introduced in 1973- Detailed modelling of the tape loop and tape heads with their artefacts, the spring reverb and the complete circuit- Creates a wide range of effects from subtle tape echo to dub delay to crazy chaotic self-oscillation- All hardware parameters, such as the typical mode selector, have been adopted and useful functions such as tempo sync, panorama, tape status, etc. have been added
