Mad Professor Deep Blue Delay, PCB version. This is a really great delay. It's a tape/analog style with an analog signal direct path, so as soon as you plug it in you get that warm vintage style echo. It's designed specifically to play nicely with overdrive and distortion, which not all delays do very well. It's perfect for that rockabilly slap-back tone, but it'll do some pretty killer deep delay tones too. This is instantly satisfying, it'll do your board and your life good!
