“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.”— KickFragrant7836 on Reddit
“The RV-6 was one that I tried, and while each setting was fine, none were especially interesting. I likely would have kept it except I also had noise issues (surprising, because I have other very quiet Boss pedals).”— bobweisfield on Reddit
“I have an find it very underwhelming and digital sounding. It does a job but it isn't inspiring. It covers many bases but is the master of none.”— fkin0 on Reddit
“I too was sadly disappointed with the RV6. I wanted to love it but it always left me feeling like it was just ok and I wanted something different. I ended up selling it and getting an MXR reverb and haven’t looked back.”— fascination_street21 on Reddit
“The RV-6 does have modulation and shimmer modes, but there isn't a lot of tweakability with them. I actually bought the RV-6 specifically to use the shimmer and mod, and ended up going with other reverbs for more ambient stuff.”— TodDodge on Reddit
“It does a lot of different types of reverbs -- but they all sound heavily digital / full of artifacts.”— kidcacophony on Reddit
“To me, its either too much or too little and I can't find a good sweet spot.”— sparks_mandrill on Reddit
Not complaints — practical notes from owners that didn't affect the score.
“Definitely not overkill. Place the Flint at the end of your signal chain for a traditional reverb. Then throw the RV-6 before your overdrive/distortion/fuzz.”— gimpsimpson on Reddit
“Just hiss (soft white noise). It's probably not even noticeable with many amps, but I mostly use a Quilter Interblock, which is very quiet.”— bobweisfield on Reddit
“I’ve been running dispatch master into RV6 set on shimmer or modulation with the tone set low. Dispatch Master is excellent on its own too”— pempod on Reddit
“I run both of those on my board, the flint for spring reverb and the rv6 for a huge plate or modulated verb”— crittyhopper on Reddit
“Try the RV6 in delay+reverb mode, with the carbon copy running into it. Can get some awesome sounds!”— El_Cactus_Loco on Reddit
“The GE-7 is already in the FX loop in this chain (Amp FX Send -> NS-2 Return -> NS-2 Output -> GE-7 -> RV-6 -> Amp FX Return). So you're saying this routing is fully correct and worth doing over front-only?”— zarjak92 on Reddit
“I almost don’t use my DM-2W anymore although I still need it for some stuff the RE-2 is just so flexible with what it can do for its size.”— RaceNo2435 on Reddit
“My favorite way to use my Boss RV6 pedals is adding reverb to things. Some people really like to use them to hold doors open. They're also pretty useful when you have a table or chair with one leg 2.5" shorter than the others.”— TicklingYourMomsAnus on Reddit
