Boss RV-500 Reverb

This is what Boss say about the RV-500:

Journey to new dimensions of time and space with the RV-500, the most powerful and versatile reverb processor BOSS has ever produced. This multifaceted creation machine features class-defying 32-bit AD/DA along with 32-bit/96 kHz floating point processing and immense programmability, putting pro-level studio reverb and more at your feet.

Twelve modes and 21 newly developed reverb algorithms deliver a huge range of textures, from complementary ambience to deep, immersive sonic atmospheres. And thanks to the RV-500’s high-octane DSP, you can access a full-featured digital delay along with every reverb patch, and even run two reverb patches at once! Adding in MIDI I/O, support for external footswitch/expression control, and USB for connection to the free RV-500 Editor/Librarian software, the RV-500 is simply the most advanced reverb pedal available, bar none.
