I’m a songwriter/composer under performance rights organization, BMI, Inc. I’m also a self administered publisher under The Mechanical Licensing Collective (The MLC). I write and record commercially licensed music, under four music libraries. And at times, I write songs for retail sale.List of positives:I did not want to spend a lot of money for this sort of ambient long decay reverb, there is one or two other companies out that that change HUGE amounts of money for this simple effect. So price at $85.00 is well worth it.I use this more for synthesizer, and it amazing on how much this improves different sound patches that I use. From piano, to strings and even the TB-303 bass synth' clone that I have.. when I max out the settings, sometimes I can get overtones to the point that the sound is totally different if that makes sense.List of Negatives:The first is a product is only as good as the company behind it, and going on 4 weeks now, the company never emailed back after sending them a message via their web site email "form". As some one who writes music and is under a few music organizations, It's surprising NOT to see any replies from a company via email.. usually there is AT LEAST a help support desk. So, customer service from the company after the sale, may be non-existent from my current experience.While it's possible to buy a 9volt battery "clip" to dc plug to power the pedal, there is no internal compartment for a battery. So you'll need to buy a power adapter that is 9v, tip is to: negative polaritylike many standard power adapter for guitar pedals (the majority).Another observation, is that the is always voltage going into the pedal, even if the pedal foot "switch" is off / bypass. While the pedal has a metal housing (which is great) it DOES get warm regardless. In my studio, I have this hooked up to a separate surge protector, so if I need to take a break, I can just power it off manually. I've seen other mini pedals that are like this as well and having them on a separate surge protector helps with powering them on and off.If you are into ambient music, this is a must have buy... Really, it's that good. - MrTom

The MOOER R7 is a great value for the money. A micro pedal containing 7 different reverb models with versatility and tweakability ranging from a simple room ambiance of a mic a few inches from an amp to Lush atmospheric modulated singing cavernous reverb. It passes signal very well and is able to accept a decent amount of boost or overdrive going through it without squashing and peaking out. The original input signal appears to be pure and unmolested adding reverb to the dry signal when the level knob is increased. All 7 of the reverb models are adjustable by 5 perimeters and savable as patches. Even when unplugged the unit goes directly to the last used model when powered up again. I found the LC and HC EQ knobs are very useful when creating large lush atmospheres as they allow the tails to be very large and full without the bass stacking up and overwhelming the original signal. The spring reverb model is also MUCH better than many pedals in this price point, if the pre-delay knob is set to 1/2 or more it will give a boing/drip. Overall this is a nice low noise, highly useful and versatile reverb pedal with saveable presets and high quality impulse models.

I have not been a fan of many modulation effects on my guitar. I have had a cheap reverb on my board in the past for the purpose of bad room sound, but I didn't use it much. Recently, I have been getting asked for a more ethereal clean sound. I did a bit of research and came across the Mooer r7. It's pretty much your standard reverb except It has that pre delay knob that allows you to make the space effect sound HUGE. That coupled with the modulated effect of the 7th preset gives me a bit of that ethereal sound my band mates were asking for. It's also worth noting that the spring section lacks the some of the drip that the surf guitar fans might be looking for.

My original review followings. This pedal sounds really good "for the price." Hopefully the replacement will last. I'm glad I finally have a working A7 but from a cost-benefit analysis perspective, the product is not worth all the trouble I went through to get it. I'd have been better off spending more money for a product from a company with reliable customer service. Seems most people get a good product though, so up to you, take your chances I guess.I only used this pedal a couple times at home. I went to use it again after a couple weeks and it didn't work at all, no sound, no light, no power. When I contacted the seller I was told that it was past the exchange period but that I should contact Mooer because the pedal was guaranteed. HAH! I had a dozen exchanges with so called "customer service" and technical support. Several requests for a video of the problem - which I provided each time. Several requests for my receipt, again which I provided each time. And each time I responded immediately with the information they requested a week or more would go by with no response. I would follow up and I would go through the same endless circle of hell. Near as I can tell a different person would handle the request each time and then forget about it. ABSOLUTELY THE WORST "CUSTOMER SERVICE" EXPERIENCE EVER. I put that in parenthesis because it's not customer service it's some kind of sadistic alternate world version where they think customer service means do everything they can to ensure the customer not only gets no service but is teased into thinking each time that something is finally going to happen and then... nothing. Absolute torture. Absolute waste of my time. Don't buy from this seller, don't buy any Mooer products. The low price isn't worth the pain, suffering and torture they will inflict on you. What a waste of money and time. My advice is every time you're tempted to spend that $50 or $60 or whatever amount... SAVE IT... save it up... until you have enough to buy a high quality pedal made by a company that will back up their products and treat you fairly and with courtesy and respect.
