The DeLayla XL was designed and developed to have the same sonic quality as the original DeLayla and adds a second delay head for the ultimate in vintage slapback echo. The response of the second head can be fine-tuned, is controllable by footswitch, and can be blended with the first head. It delivers warm, smooth delay and echo reminiscent of vintage tape units, but with modern features. The XL has a tap tempo and a built-in power supply.
