The Slapback Delay is a Dual, PT2399 based delay which offers around 700ms of gorgeous delay per section. The pedal is set up as two totally separate delay circuits internally cascaded into one another. You can separate the two pedals by using the routing jacks on the top of the pedal. You can run each channel in stereo to two different amps or simply split them up and run one into the front of your amp and the other through you effects loop. The Slapback really shines with the two pedals cascaded in mono into one another. The result can give you lush chorus like sounds or even reverb like sounds. Another unique feature of the Slapback is the oscillation toggle and middle stomp switch. You can select which side of the pedal that will runaway using the middle latching stomp switch with the oscillation toggle. The foot switch will latch as when you bypass the side that is set to runaway it will continue to do so if you leave the foot switch engaged. Hence the LED next to it, this will let you know if the middle stomp switch is active or bypassed. The Slapback Delay runs on an industry standard 2.1mm center negative 9VDC power supply. There is no option for battery power due to the size of the circuit and components in the pedal. The pedal measures 5.7 inches by 4.7 inches.
