seems to be a good recorder, but it is rather complicated and the instructions are no help at all.

I bought this to replace one that I burnt out by using an improper adapter. It had some visible wear and tear on the outside, but still works good as new. I gave it a 4-star rating because the learning curve is very big for this recorder. The directions are very unclear and I've only been able to find out how to use it by trial and error. Having said that, once I figured out the basics for recording, it's easy, very portable and less expensive than some of the newer models. I record a completed piece directly from my digital piano and then convert to .mps 3 which makes it easier to transmit electronically. I know that I can add rhythm and special effects with the recorder but haven't figured it out.

This item is awesome! After a hour very easy to use and the recordings sound great. The only downside is you must buy a ac adapter because the batteries go out in less than 30 min. Also you need a 1gb card but those are hard to get but I love this thing. The drum patterns are great and the guitar effects are not bad

I have never been disappointed with any Boss product that I’ve ever purchased. The electronics are solid and deliver great performance. This device has been compatible with every output channel of audio equipment with which it has been connected. The design allows the user all the flexibility needed to capture and manipulate audio signals. Boss has not scrimped on the engineering and I am satisfied with the overall results. Definitely worth the money spent.

In my opinion, this is a great little 4 track recorder. The effects and drum loops sound great! You can also use it to play your MP3's when you are not using it as a recorder! If you have never used a BOSS recorder before, you might find navigating the menu(s) a bit difficult at first. Most of the functions are basically the same as other BOSS multi-track recorders I have used so the learning curve was fairly easy for me.The only downside I have found so far (besides navigating the menu's) is battery life. This little guy is power hungry! Either invest in the optional a/c adapter or, buy a couple of sets (4 batteries) of NIMh AA rechargeable batteries, at least 2000mah, and a charger. I prefer to use batteries and the NIMh's hold up fairly well.Even though this recorder came out in late 2009, I would still recommend purchasing it, especially if you can get a "new" one for $150 or less, like I did on Amazon.com.

The product I purchased was broken when I recieved it. I had to send it to the manufacture for repair. In the future, if I purchase anything from Amazon again, I will need to be careful who I purchasing an item from. Thanks Victor Bernal

I am a guitar player who travels a lot, and I was looking for something to take with me when I travel frequently to record ideas and to practice. I wanted portability, ease of use, and decent sounding guitar tones.First, the cons. This Micro BR is very confusing to operate and not at all intuitive. This is the biggest complaint that I have about this product. You will spend way too long wasting your time reading the manual and figuring out how to use it, only to later forget how to perform a particular function. If you are a guitar player, I think you find the clean tones to sound very good and the distorted tones to sound very cheesy.As far as the pros to this unit, I think the main advantage is its size. If you MUST have something this small to record ideas and want to have basic multi-track functions, and don't mind spending a long time learning how to use it, then you will probably be satisfied with it.Otherwise, save your money and time and save up for something better!

I have had this thing only one week, and it is one of the coolest things I have EVER bought. Period. I still gaze at it everyday and salivate, the way you might on your new car. But this only cost me $177 so it feels even sweeter.Before I bought, I read the reviews here and was worried it would be too menu based and techy. However, with less than one week of fumbling around and (joyfully) playing with the device, I have recorded the RH piano section of Sweeny Todd on track 1, the LH section on track 2, bounced them together to a new track 1, added my own vocals to new track 2(both me and piano recorded with built in AWESOME mic). Then I mastered it down to one track, and bounced it to an MP3 file. (ALL INSIDE this tiny device). And I only read the instruction book for maybe 10 minutes.After I had my MP3 file, I used the USB out on the device to plug into my Dell XPS desktop. Then I used iTunes to put the file of ME, ME, ME onto my iPod!That screams!Last night, I used the device to record, in one take, my entire 3 HOUR rehearsal for the musical I am in, Urinetown. (I bought a two-pack 2 GIG SD cards at Costco yesterday for $35. 3 Hours on High Quality setting only took about 1/3 of the 2 GIGS!) (The device came with a 128MB chip that I was earlier able to record 1 hour 38 minutes onto.) I set the recorder next to the left wall of a very large, echoey warehouse space we are rehearsing in. Hardly a recording studio! It's been crazy practicing there, because even if two people are whispering in the corner you can here it everywhere, in a distracting way. Understand the cast has 30 PEOPLE, 3 of them hyper 14 year olds, a couple senior citizens, and all around, a boisterous, A-D-D type of crowd! Add yelling directors, assistant directors, the musical director, and the pianist, and, well you get the picture. I didn't even tell people I was recording.So even in conditions like this, I have been listening to the 3 hours again today and I can't believe how good it sounds. It sounds as good as shows I was in back in high school that we recorded using multiple Shure SM57 microphones tied through a mixing board into a sweet 80's tape deck rack.I would have killed to have had this thing during my college days. I could have recorded and archived all my wonderful lectures on my hard drive (incredibly this ENTIRE DEVICE is much smaller than that old hard drive!) You can even listen to songs or lectures in the MP3 mode, and speed it up to 200% or slow it down to 30%, while keeping the pitches all in tune. AMAZING.If I lost this thing or dropped in water or somehow destroyed it, first I would cry. Then I would get very, very angry. Then I would cry some more and throw a full-on temper tantrum unlike any seen from me since I was 5.Then I would beg, borrow, or steal to get another one.Actually I'd come right here to Amazon and order it next day air. But I really would cry at first.
