You know that feeling when you buy a piece of gear expecting it to be a "placeholder" until you can afford the boutique version, but then five years later, it’s still there? That is basically the life story of the Boss RV-6 Reverb. Honestly, it's weirdly resilient. In a world where every boutique brand is trying to out-shimmer each other with $400 pedals that require a PhD to program, Boss just keeps shipping this gray box. It doesn't have a screen. It doesn't have MIDI. It just works.
Most people pick this up because they need a reliable workhorse. You’ve probably seen it on the boards of guys like Joe Bonamassa or Gary Moore, and for good reason. It’s built like a tank, which is a cliché because it’s true—you could probably use an RV-6 to defend yourself in a bar fight and then go play a three-hour set with it immediately after.
What most people get wrong about the "Digital" sound
There is this lingering myth that digital reverbs are cold or "sterile." Look, we aren't in 1992 anymore. The Boss RV-6 Reverb uses high-end DSP that actually keeps your dry signal analog. This is a huge deal. When you're playing a nice Strat through a tube amp, you don't want your core tone converted to 1s and 0s and back again. The RV-6 blends the digital effect on top of your analog dry path. This is why it sounds so much more "alive" than some cheaper competitors.
The Modes:

- Room, Hall, and Plate: These are your meat-and-potatoes. The Plate setting is particularly good—it has that metallic "zing" that makes a lead line pop without getting muddy.
- Spring: Some people hate digital spring. I get it. But the RV-6 version is surprisingly "drippy." It’s not a Fender 6G15 outboard tank, but it’s better than the reverb built into most modern amps.
- Shimmer: This is the one that gets all the YouTube attention. It’s ethereal. If you’re doing worship music or ambient soundscapes, this is your best friend. Pro tip: Roll the tone knob back to about 9 o’clock to take the "ice pick" off the top end.
- Dynamic: This is the secret MVP. It’s basically "ducking" reverb. If you play hard, the reverb stays quiet so your notes stay clear. As you let a chord ring out, the reverb swells in to fill the space. It’s genius.
- +Delay: It’s a reverb and a delay in one. Perfect for a "one-pedal" grab-and-go board.
The RV-5 vs RV-6 Debate
If you hang out on Reddit or the Gear Page long enough, you'll find people swearing by the older RV-5. They usually point to the "Modulated" mode on the RV-5 as being superior. Is it? Well, it's different. The RV-5 modulation is very deep and almost chorus-like. The Boss RV-6 Reverb modulation is more refined and subtle. If you want a 1980s dream-pop wash that never ends, maybe track down a used RV-5. But for literally everything else, the RV-6 is the better pedal. It has more headroom, the algorithms are newer, and the shimmer is actually usable.
Wait, did I mention the expression pedal input?
You can plug in something like a Roland EV-5 and control the depth of the reverb with your foot. This turns the pedal into a performance tool. Imagine playing a dry, chunky rhythm part and then slowly "leaning into" a massive hall reverb for the solo. It’s a lot of power for a pedal that costs under 200 bucks.

Why the Dynamic Mode is actually a game changer
A lot of reverbs turn into a "wash" the second you start playing fast. It’s like trying to talk in a cathedral; eventually, everything just sounds like a blur. The Dynamic mode on the Boss RV-6 Reverb fixes this by listening to your pick attack. It’s smart. If you’re shredding or doing fast hybrid picking, the pedal stays out of the way. The second you pause, the "cave" opens up. It makes you sound like a better player because it manages the mix for you in real-time.
Setup Tips for the Modern Player
If you really want to hear what this thing can do, you have to run it in stereo. Seriously. Plugging into two amps—or even just two channels on an interface—completely changes the experience. The "Modulate" mode in stereo feels like the room is physically expanding. If you're stuck in mono, you're only hearing about 60% of what the engineers intended.
Another thing: Don't be afraid of the Tone knob. On the Boss RV-6 Reverb, the Tone knob isn't just a simple EQ filter. It actually changes the characteristics of the reverb tail. In Shimmer mode, it controls the brightness of the "octave" shifted reflections. In Room mode, it simulates the difference between a room with hardwood floors and one with thick carpet. It’s a very powerful control that people often leave at noon. Don't do that. Move it.

Making it work for you
If you’re looking to add the Boss RV-6 Reverb to your rig, here is exactly how to get started:
- Check your power: Don't use a cheap daisy-chain power supply. Digital pedals are thirsty and sensitive. Use a dedicated, isolated power output to avoid that annoying high-pitched hum.
- Placement matters: Put this at the very end of your chain. If you have a delay, try the reverb after the delay for a traditional sound, or before the delay if you want to get weird and "shoegazy."
- Experiment with the "B" Input: If you plug only into Input B, the pedal outputs 100% wet signal. This is great for parallel loops or if you’re using the pedal as an "insert" on a mixer in a studio setting.
- Try the Slap-back trick: Put the pedal in +Delay mode, turn the Time all the way down, and the Level up. You get a great rockabilly slap-back that feels thicker because of the underlying reverb.
The Boss RV-6 isn't the "fanciest" pedal on the market, but it is probably the most reliable. It's the "Toyota Camry" of pedals—it might not be a Ferrari, but it will start every single morning and get you exactly where you need to go without any drama. Whether you're playing a basement show or a stadium, this pedal has the fidelity to keep up.
