— neverw1ll on Reddit
“Big fan of RV-6. When I got it I thought it was “pretty good” but after a couple of years I love it.”
— ziganaut on Reddit
“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.”
