With the Blue Ocean it's really easy to quickly dial in some great delay tones right out of the box. It's incredibly natural sounding and lets the tone of your guitar shine through. The CP19 has up to a 600ms delay time and when used in conjunction with Repeat can be used to create either slap back effects or standard delay. Takes a 9v battery or power supply and is True Bypass design design, with aluminum alloy casing like most Caline pedals. Build in a durable metal housing with sturdy knobs and a blue on LED.
