Building on the legacy of Boss's reverb line, the RV-6 packs a host of new features such as new studio quality reverb algorithms plus eight separate modes including Shimmer and Delay+Reverb, and Dynamic for automated depth attenuation. Impressively modern but able to summon reverb sounds across the wide universe of genres and decades, the RV-6 is an excellent upgrade for the Boss enthusiast or the perfect entry point for newcomers.
