Okay, these are backordered everywhere and we are already down to one left in stock. Here is the quick rundown: it is a digital delay chip with 6 different voices and each has its own modulation style. These range from tape warble, to chorus, to filter sweeping. However, that chip is enclosed in a 22 volt analog preamp that captures the glory of those Echoplex units. It has amazing headroom and it just sounds wide open. It is expression pedal controllable and has a secondary foot switch for runaway oscillation. Catalinbread absolutely killed it. Click the photo to see the official demo from Catalinbread.
