The Carl Martin DeLayla was designed and developed with one goal in mind: To create a superior analogue delay pedal, incorporating some of the same features used in vintage tape delay units. To achieve this, we have incorporated a second delay tap (similar to using two heads simultaneously on a tape delay). The TAP footswitch is used to turn the second tap on or off. The TAP knob controls the mix of main delay vs. second tap delay. Clockwise movement favours the second tap; counter clockwise favours the main delay. The result is a warm, smooth sound reminiscent of the vintage tape units used in the 50's and 60's. The DeLayla is able to capture one of the hardest sounds: that authentic rock 'n roll slapback echo that digital processors are unable to emulate. The unit also features a built in regulated (+-12V) power supply.
