  • Quick to dial in, with no hidden button combos or manual to keep referring back to

What Boss RV-6 Reverb owners say

The Reverb is a gem. That pedal has a lot of settings to get some really cool sounds out of it.

Big fan of RV-6. When I got it I thought it was “pretty good” but after a couple of years I love it.

Had the RV-6 at one point, but found it too metallic. All Boss reverbs are like that to my ears though. Modulated is the best algo on the RV-6, but it seriously pales in comparison to Mercury7 modulation.
