Acceptable Battery Life
Some reviews that I read before buying the DB-30 questioned longevity of the battery. Today is my first battery change after two and a half months of daily usage. The battery didn't die, per se; the metronome just started responding oddly to some input. A new battery fixed that. Longer battery life is always a plus, but I am fully satisfied with that of the DB-30. I also like the metronome very much because of its size, ease of use and overall quality.

Best Metronome for the money
I am a professional organist and use a metronome on a daily basis. I have gone thru at least 9 different metronomes in the past 10 years. The KLIQ was nice until it lost its mind before the year was up. I own a few Korg TM-50 units and they are real good, but they are a little too quite for my purpose (pipe organs are loud). This is the first time I have tried any of the Boss metronomes and was very immediately impressed with the functionality of it. If there was a higher grading than 5 I would have given this more than five stars. What I like about the Boss DB-60: Ease of use. I love the actual sound, it is more of a old wooden tock instead of a digital ping. I can instantly add or change half beats or third beats on the fly and give them different volumes. There is nothing to like about this DB-60, and if and when it breaks ( I am very hard on equipment) I will buy another Boss DB-60. I have finally found a metronome I really like after 50 years in the business.

Very Good Metronome With Nice Features
I play guitar and I bought this for groove training purposes. It has four voices for the metronome and several drum beats to choose from. The first three metronome voices are various clicks, the fourth is a voice counting out the beats. The click sounds are all fine and are loud enough for playing an acoustic or turned down electric to. If I want to crank it up there's a headphone out that I can run into the amp. The voice count seemed a bit hokey to me at first, until I was trying to learn a solo with a long break before coming back in on an off beat. The voice count was super helpful for coming back in at the right place. It has an accent beat that comes in at the top of a measure, a quarter note beat, an eight note beat, a sixteenth note beat, and a triplet. The volume for each can be set with the sliders on the front panel. You can use those volumes to dial in exactly what you need for training. Things I do with it are turn up the accent and the quarter note beat full and the eighth note to half for most practices. I turn the accent and the eighth notes on (leaving the quarter note mute) so that only the up beat is audible, which is great for practicing improvisational soloing and improving your groove. The triplet beat is very handy for practicing music that shuffles or swings. There are quite a few drum beats you can use as well. The drum sounds are not great, suitable for practice only or jamming with friends. Most of them are strait four (or eight or sixteen) beat and there are several shuffle beats. The only three four beat is Waltz, would be nice to have a few more options than that. It has onboard memory and you can store settings. If you set the metronome up for a specific song, it can be recalled easily. The kick stand leaves a bit to be desired. It's made of very thin plastic and feels fragile. I feel like I have to be very careful not to break it, having the metronome up at an angle is important to me when practicing. All in all I would recommend this to any guitar player who's looking for a metronome that goes up and above the standard quarter note clicking. It's extra features have come in very handy in practicing various songs and working on specific techniques. It has become a staple in my practicing.

An awesome upgrade from the Boss DB-88!
I have been using the Boss DB-88 metronome previously. I used that model since 1999 when I was in my high school drum line. It was a great metronome to use in a drum line as well as playing a drum set. I eventually bought my own in 2003. The DB-90 has been out for a while now - I remember wanting to get it as soon as it came out, but I figured I'd wait until my good old DB-88 stopped working. Unfortunately, that time as come (after using my own for nearly 9 years!!!) The DB-90 is packed with SO MANY more features compared to the DB-88. I won't get into them all here since you can find them in the production description. I'll just say that the biggest upgrade for me going from the DB-88 to the DB-90 is the amount of memory slots you get. I have been used to only having 8 slots for so long. I was always struggling to figure out which times to delete from the metronome when I needed more room. Luckily, the DB-90 comes with 50 memory slots! I no longer need to decide which times to get rid of, because I have WAY more than enough room to save all of the times that I need! All-in-all, this metronome is a great replacement for the DB-88. I am extremely satisfied. To anyone who is looking for a metronome that will help you grow your skills, this is definitely the one. It has a great range of features that can help basic to the even most advanced players progress with playing to a click. I don't think any other metronome is as good as this... Boss knows has to produce perhaps one of the (if not, best) metronomes in the industry. I have been playing drums for 19 years to date, and I cannot recommend any other metronome as much as this one. My vote: BUY IT - You will not be disappointed!

Easy to use and works well
This metronome is easy to use, has a clip for your shirt pocket or belt and easy to use with headphones. It has just the right amount of features you need.

Horrible when used with headphones
This is an entirely competent metronome. You can easily adjust the tempo, change how many beats, which beats are sounded, and choose more complex rhythm combinations(e.g., 6-7, or 4-3 time). That's all good, and it's really easy to do. It also has a rotary volume control and it can get about as loud as my cell phone's low battery warning. It only emits one sound, an uninspiring chirp which is slightly higher in tone on the first beat of the measure. It sounds like you flashed back to the 80s and someone is playing pong. Some people might find it annoying, but you'll probably get used to it. There's a handy clip on the back. It will also play continuous computerish reference tones at different note values, if that's of use to you. Finally, the very useful display makes all the functions pretty intuitive and has a good pendulum and flashing LEDs that help visualize the tempo. There is also a mini stereo jack for use with standard headphones. That's where it's horrible. When using the built-in speaker, the volume control is gradual, as expected. When using the headphone jack the volume control isn't gradual - it really jumps up extremely quickly. Without headphones, you'd probably have the volume around 70% or so. However, with the headphones in, anything below 10% isn't really audible and anything above around 15% will be like an ice pick piercing your ear. So, if you go between built-in speaker and headphones (I do, depending on the time of day), you will eventually blow your ears out with this when you forget to turn it down. To make matters worse, sure you can find that sweet headphone volume spot of between 10-15%, but the sound through the jack is absolutely horrible and distorted. What is a pure chirp from the built-in speaker is pretty muddled/distorted in headphones. What a waste that Boss went cheap and careless on that function. I use this for drumming, so that may explain my use scenarios. If you don't use this with headphones, you will probably be very satisfied and it's a good value in its price range. However, because the headphone volume problem is significant, I docked it two stars since it's a one star product in that regard.

Best digital metronome there is
I had bought one 12 years ago and I’ve used it everyday until I had to change to a new one this year. Very rigid, and durable. Absolute perfection on the technical side. Now once I got a new one, I know I’m sorted for at least a decade!

Çok işlevsel
Gayet güzel bir metronom. 1 saat sonra kendisi duruyor. Dinlenmek için iyi bir özellik. Çok farklı ritimleri ayarlamak da cabası. Dikkat edilmesi gereken şey, kullanım kılavuzunda da yazdığı üzere, bir anda durarak 120 bpm’de sabitleniyorsa pilinin değiştirilmesi gerekiyor demektir.

A Pianist's Perspective
If you're learning to play the piano, then a decent metronome is something that you cannot do without. Most pianists tend to prefer the classic wooden wind-up variety, and having listened to the sounds that are produced by most of the cheaper electronic metronomes out there, I can understand why. There's nothing that can beat the timeless "donk-donk-donk-ding!" sound of a traditional metronome... or is there? Enter the Boss DB-90 digital metronome, made by Roland. Instead of producing cheap-sounding digital beeps, the DB-90 actually plays back recorded samples of a traditional wooden metronome. The traditional metronome pendulum is also simulated on the LCD screen via a series of lines that give the illusion of a moving pendulum, whilst two red LEDs just above the screen flash in time with the beat. In spite of looking quite complicated, the DB-90 is actually very easy to operate. Press the "Power" button to turn it on, then press the "Beat/Pattern" button (bottom row on the left) and rotate the big orange knob to select the number of beats per bar (displayed on the screen under "STYLE"). Now press "Tempo" and rotate the big orange knob to select the number of beats per minute. Then press the big "Start/Stop" button to start the metronome. Now you can have some fun with the sliders. The first slider controls the volume of the bell; the second slider controls the volume of the beat; and the next three sliders allow you to sound eighth-notes, sixteenth-notes and triplets. You'll probably not want to use these very much, but they're there if you ever need them. The last slider is the overall volume control. This metronome has plenty of volume to it, so if you're playing a digital piano, you'll probably be only using 30% volume. Want to try using a different sound for your metronome? No problem. Pressing "Voice" allows you to use the big orange knob to scroll through the four built-in voices. In addition to the standard "wooden" tone, there is a higher-pitched tone, a lower-pitched tone and a human "counting" voice. The DB-90 includes a backlight for the screen, but pressing the "Light" button only turns it on for 5 seconds. If you want the backlight to remain on, you'll first have to press the "power" button to turn the unit off, then hold down the "light" button whilst pressing the "power" button again to turn the unit back on. The backlight will now remain on until you switch the unit off. You can do this any time you like without worrying about losing your rhythm settings, because everything is saved to memory automatically. In terms of connectivity, the BD-90 has it all. There are two headphone sockets (3.5mm and 6.35mm), a 6.35mm socket for you to connect a start/stop footswitch, a 6.35mm 2-way socket for you to change the rhythm memories (up/down) with your foot via another special footswitch. There are also some input sockets, including a MIDI-in, although this probably goes beyond what most people will actually use. Once you've started using this metronome as part of your daily music practice, you'll probably want to buy a power supply for it, because it chews through batteries quite quickly. Only three small negatives: (1) Roland wired this metronome to switch seamlessly to using battery power in the event of a cable disconnection or a power failure. Whilst I can understand why they have done this, it also means that if you connect your DB-90 to an external power supply, and then you forget to turn your power supply on, the unit will continue to operate normally, but using battery power instead. This feature might result in you going through more batteries than you intended. (2) The metronome has 50 user memories so that you can save and recall your favourite rhythms. However, when you change the battery, all your user memories get reset, and there is no way of backing up your data. (3) The pull-out plastic stand at the back of the unit feels a bit flimsy. When deciding which metronome is right for you, certain challenging questions will need to be asked. Is it really worth paying £105 for a complicated-looking digital metronome that requires its own separate power supply when you can buy a traditional wood-effect wind-up one (complete with bell) for under £30? I wrestled with this dilemma myself, and I chose to go digital. Your choice might be different to mine, but the most important thing is to buy a metronome that you can live with, and which makes your daily music practice a more enjoyable experience.
