Roland RV-6 Effects pedal for Guitar / bass, with 5 Year Warranty (when registered) The Boss RV-6 contains the latest BOSS Digital Signal Processors and updated algorithms, giving you eight highly musical reverb effects in one compact pedal. Add body and depth to your core tone with standards like Room, Hall, and Plate, dial up swirling richness with the Modulate setting, or surf it up with a vintage-style Spring reverb. Dynamic mode automatically adjusts the effect depth to your playing touch, providing deep, immersive reverb that won’t turn your tone to mud. And modern players will love the new Shimmer and Reverb+Delay modes. The RV-6 makes getting high-quality reverb sounds with your guitar quick and easy All you have to do is just select a sound mode, tweak the knobs to taste, and play. But whilst it is simple to use, the RV-6’s sound is rich and sophisticated. Each mode includes a huge array of detailed reverb parameters, all perfectly tuned for guitar by the BOSS engineers with direct input from many pro players and sound engineers. Even as you adjust the selected mode with the Time and Tone knobs, many parameters are simultaneously adjusted inside to create the ideal voicing for every setting. Designed to be used with the Boss Expression pedal for extra versatility.
